For the best performance of the instruments, please carefully read these instruc-
tions and keep them in a convenient location for future reference.
General Handling Precautions
Before starting work or operation, be sure to check that the instrument is
functioning correctly with normal performance.
Do not aim the instrument directly into the sun .
Aiming the instrument directly into the sun can result in serious damage to the eyes.
Damage to the instrument could also result from exposing the instrumentÅfs objective lens to direct sunlight. The use of a solar ﬁlter is suggested to alleviate this problem.
Setting the instrument on a tripod
When mounting the instrument on a tripod, use a wooden tripod when possible. The
vibrations that may occur when using a metallic tripod can effect the measuring precision.
Installing the tribrach
If the tribrach is installed incorrectly , the measuring precision could be effected. Occasionally check the adjusting screws on the tribrach. Make sure the base ﬁxing lever is
locked and the base ﬁxing screws are tightened.
Guarding the instrument against shocks
When transporting the instrument, provide some protection to minimize risk of shocks.
Heavy shocks may cause the measurement to be faulty.
Carrying the instrument
Always carry the instrument by its handgrip.
Exposing the instrument to extreme heat.
Do not leave the instrument in extreme heat for longer than necessary. It could adversely affect its performance.
Sudden changes of temperature
Any sudden change of temperature to the instrument or prism may result in a reduction of measuring distance range, i.e when taking the instrument out from a heated vehicle. Let instrument acclimate itself to ambient temperature.
Battery level check
Conﬁrm battery level remaining before operating.
Memory back up
The instrument has a built in battery for memory back up. If the battery power is low,
ÅgBack up battery empty Åh will display. Contact your dealer, to replace the battery.
Taking the battery out
It is recommended not to take the battery out during the power is on. All the data stored is
possible gone at that time. So please do your assembling or taking the battery out after the power is off.

2-2 2 PREPARATION FOR MEASUREMENT
2.2 Setting Instrument Up For Measurement
Mount the instrument to the tripod. Level and center the instrument precisely to insure the best
performance. Use tripods with a tripod screw of 5/8 in. diameter and 11 threads per inch, such as the Type E TOPCON wide- frame wooden tripod.
1. Setting up the Tripod
First, extend the extension legs to suitable lengths
and tighten the screws on their midsections.
2. Attaching the Instrument on the Tripod
Head
Place the instrument carefully on the tripod head and slide the instrument by loosening the tripod screw. If the plumb bob is positioned right over the center of the point, slightly tighten the tripod screw.
3. Roughly Leveling the Instrument by Using
the Circular Level
1
Turn the leveling screws A and B to move the
bubble in the circular level. The bubble is now
located on a line perpendicular to a line running through the centers of the two leveling
screws being adjusted.
2
Turn the leveling screw C to bring the bubble
to the center of the circular level.
4. Centering by Using the Plate Level
1 Rotate the instrument horizontally by using the Horizontal motion/clamp screw and place the plate level parallel with the line connecting leveling screws A and B, and then bring the bubble to the center of the plate level by
turning leveling screws A and B. 2
Rotate the instrument 90° (100g) around its vertical axis and turn the remaining leveling
screw or C to center the bubble once more.
3
Repeat the procedures
1
and
2
for each 90°
(100g) rotation of the instrument and check whether the bubble is correctly centered for all four points.
5. Centering by Using the Optical Plummet
Telescope
Adjust the eyepiece of the optical plummet
telescope to your eyesight.Slide the instrument by loosening the tripod screw, place the point on the center mark, and then tighten the tripod screw. Sliding the instrument carefully not to rotate that allows you to get the least dislocation of the bubble.
6. Completely Leveling the Instrument
Leveling the instrument precisely in a similar way
to 4. Rotate the instrument and check to see that
the bubble is in the center of the plate level regardless of telescope direction, then tighten the tripod screw hard.Leveling screw ALeveling screw C

Note:
1) The battery operating time will vary depending on the environmental conditions such as
ambient temperature, charging time, the number of times of charging and discharging etc. It is recommended for safety to charge the battery beforehand or to prepare spare full charged batteries.
2) For general usage of the battery, see Chapter 12 “POWER SOURCE AND CHARGING” .3) The battery power remaining display shows the power level regarding to the measurement
mode now operating.The safety condition indicated by the battery power remaining display in the angle measurement mode does not necessarily assure the battery‘s ability to be used in the distance measurement mode.It may happen that the mode change from the angle mode to the distance mode will stop the operation because of insuf ﬁcient battery power for the distance mode which consumes more
power than angle mode.Note that the EDM unit is working when the pictogram for zero set and the battery power remaining display shown at the power ON, which shows as an easy battery check before use.
4) When the measurement mode is changed, it rarely may happen that the Battery Power
Remaining Display will decrease or increase two steps momentarily because of the accuracy of the battery checking system is rough. It is not trouble with the instrument.

2-6 2 PREPARATION FOR MEASUREMENT
2.6 Vertical and Horizontal Angle Tilt Correction
When the tilt sensors are activated, automatic correction of vertical and horizontal angle for
mislevelment is displayed.To ensure a precise angle measurement, tilt sensors must be turned on. The display can also be used
to ﬁne level the instrument. If the (TILT OVER) display appears the instrument is out of automatic
compensation range and must be leveled manually.
●GTS-600 compensates both the vertical angle and the horizontal angle readings due to inclination
of the standing axis in the X and Y directions .
●For more information about dual axis compensation, see Chapter “APPENDIX” .
●The display of Vertical or Horizontal angle is unstable when instrument is on an unstable stage or a
windy day. Y ou can turn off the auto tilt correction function of V/H angle in this case. To set TILT correction mode ON/OFF , refer to next page or Chapter 7 “PARAMETERS SETTING MODE” .

Reference : How to Collimate
1Point the telescope toward the light. Turn the diopter ring and adjust the diopter so that the cross
hairs are clearly observed.(Turn the diopter ring toward you ﬁrst and then backward to focus.)
2Aim the target at the peak of the triangle mark of the sighting collimator. Allow a certain space
between the sighting collimator and yourself for collimating.
3Focus the target with the focusing knob.
*If parallax is created between the cross
hairs and the target when viewingvertically or horizontally while looking
into the telescope, focusing is incorrect ordiopter adjustment is poor. This adverselyaffects precision in measurement or surveyEliminate the parallax by carefully focusing
and using diopter adjustment.

This program uses the input coordinate values of the occupied point, (instrument), and backsight point
to compute the backsight orientation direction angle.
The occupied coordinate input display appears as (BS:M-POINT). The backsight input display appears
as (BS:T-POINT). After the coordinate values are entered for both points, the instrument computes the backsight direction angle for orientation. Only the occupied coordinate values are stored in memory if the option is selected to (ON) in the Parameter Modes option. See Chapter 7 “PARAMETERS SETTING MODE” . The program does not store the backsight coordinate values in memory.

4.6 Layout
The layout program will assist the user to stakeout point numbers with coordinate values (NEZ) on the
job site. The coordinate points can be transferred to and from the internal memory of the GTS-600 series using a PC. The communication parameters are selectable on the GTS-600 series for Baud rate, parity, stop bit, and protocol.Coordinate data consist of a point number with north, east and elevation coordinates. The coordinate data is stored in job names. A Job name can be up to 10
characters long. A maximum of 1000
coordinate points can be stored in memory. A total of 10 jobs having 100 coordinate points or 2 jobs
having 500 points each can be stored in the instrument. Job names can be alpha and numeric. Job can
be renamed within the Job Manager option. If point numbers are not found in a job during the layout setup procedures, the software will prompt the user for the coordinate values. When using duplicate point number’s in a job, the last duplicate point number stored in memory will be used. All other points having the same number will be ignored.A job name must be created or selected to store coordinate values for the side shot or resection routine. If a job name is not created when doing the side shot or resection routine, the GTS-600 series will automatically create a default job identi ﬁes as (???1). The default job consists of three question marks
followed by a numeric value starting with (1) for the ﬁrst default job. When there are multiple jobs in the
GTS-600 memory, the current job or the last job selected is where the coordinates are stored. The software provides two options to delete coordinate points within a job, Erase a Black of Points or Erase One Point.Two programs, Side shot and Resection, are available under the New Point option that will calculate
coordinates and store them in the current job. The side shot program calculate the coordinates (NEZ) from the angle and distance measured. Instrument height and rod height are used to calculate the (Z) coordinate.In the Resection program the angle and distance measured to two know points, stored in the job, are used to measure and calculate the coordinate values for the new occupied point number. After measuring the known points, the residual error for the horizontal distance and elevation are shown on the display. There is an option to record the new occupied point in the job.

The transfer data option sends and receives coordinates to and from the computer. The
communications parameters are set by the user for Protocol, Baud rate, Parity, and Stop bits. Topcon‘s interface cable from the GTS-600 to the computer is used for the data transfer.
Job names can be renamed by using the Rename a Job option. When the rename option is selected,
the current job will be renamed unless you select a different job using the View Memory option.
There are two options to delete jobs in memory, Delete a Job and Delete All Jobs. The Delete a Job
option will delete one job from memory. The current job is erased unless another job is selected using the View Memory option. The Delete All Jobs option will erase all the jobs in memory.
Transfer Jobs
The protocol default parameters are highlighted on the GTS-600 series.
The Transfer Jobs option will send and receive jobs to and from the PC. In the receive option, the
software in the instrument will not allow the new job from the PC to overwrite the current job. A warning “Coordinate data ﬁle already exists” will appear when receiving the job from the PC. If you select (YES),
the current job is erased and the job received from the PC is added to memory. If you select (NO), a message appears to receive another job without erasing the current job. This will add the new job to memory and the received job becomes the current job.
The send option will transfer jobs from the instrument to the PC. The current job will be sent to the PC

Input Coordinate Data
The input coordinate data routine is used to manually type in point numbers with coordinate values.If
there are no job names found in memory, the software will ask to create one. If there is a job in memory the coordinates will be stored in the current job or another job name can be selected. Select a job name before choosing the Input Coordinate Data option. A job name can be a total of 10 characters, alpha and numeric. The job name is not created or stored in memory until you have stored the ﬁrst point
number with coordinates.
The ﬁrst prompt screen is to input the point number. The (REC#) in the upper left corner of the display,
represents the record number for the point number and it‘s coordinates.once the point number entered, the next prompt screen allows the user to input the north, east and elevation. The [F6] key is the backspace key to move the cursor from right or left and the [F1] key is to exit back to the Coordinate data main menu. Press the [ENT] key to store each ﬁeld of data. After entering the elevation data, the
point number prompt display appears and increments the last point number (+1). Press the [ESC] key to cancel the coordinate data input option.
The instructions below show hoe to create a job name from the Coordinate data input option and
manually type in a point number with coordinate values. (Assume that there are no job names memory
for this example).

4.6.4 New Point
In the New Point option there are two features available to collect coordinates, Side Shot and
Resection. When collecting a side shot point, the point number, north, east, and elevation are stored under a job name. The feature to set the back sight direction, Setting a Direction Angle, is optional when collecting a side shot point. The software provides the user with the option to set the direction angle or to skip this option.NOTE: If the direction angle to the back sight was established during the layout feature, and you haven‘t turned off the instrument, you can skip the Setting a Direction Angle feature in
side shot collection. But, we recommend that you check the direction to the backsight before collecting side shot points.
Once the direction to the back sight is complete, the side shot point number and rod height are typed in
and the instrument can be sighted on to the prism to collect the point coordinates.
Follow the instruction below to collect a side shot point.

accurately. This is accomplished by showing the instrument person distance instructions which are then passed on to the rod person. The distance instructions are to move (BACK), towards the instrument, (GO) away from the instrument, and to move (RIGHT) or (LEFT) to get back online with the layout point. The (RIGHT) and (LEFT) instructions are helpful when the rod person is very close to the layout point. Please refer to the diagram and instructions below.
●Another feature that layout accomplishes is the cut or ﬁll information. Using the last rod height
previously entered, the Total Station will display the cut (DOWN) or ﬁll (UP) information to the
instrument person.

4-38 4 PROGRAM MODE
Layout with Guide Feature
Refer to the previous section 4.6.2- Setting a Direction Angle and Layout a Point (step 1-11).
At the layout screen, the example below will pick up at the Guide feature.
Operating procedure Operation Display
1From the angle and distance layout screen,
press [F5] (GUIDE).
2The next screen will display the distance to move right or left to the layout point and to
move back toward the instrument or away from the instrument. The cut (DOWN) or ﬁll
(UP), on the last line of information, is calculated using the rod height previously entered.[F5]
3When the measuring point is within ±5mm
from standard layout point, the word “KEEP”
and (+) or (-) signs are displayed.
Function of GUIDANCE
Using the function of guidance, it is possible to guide a person of prism side as shown below.This function is useful when it is dif ﬁcult to collimate the layout point (P1) directly during executing a
layout mode. dHR = 52°10'16"

4.7 Line Measurement (LINE)
The Line Measurement program allows the user to measure the height of an inaccessible object above
a point. Both the inaccessible object and the point are located along an established base line. Two prisms, A and B, are set up apart from each other below the object to established the base line. The horizontal distance is measured and set in the instrument for both prism A and B. The screen then shows the vertical distance from prism A and B, the horizontal distance from the instrument to prism B, and the distance along the base line and the screen will display the vertical distance from prism A to that point, the horizontal distance from that point. Additionally, the vertical distance between two points
on the base line, Points G and L in the diagram, can be measured.

8-18 CHECK AND ADJUSTMENT
8.1 Checking and adjusting of instrument constant
Normally, the instrument constant does not have discrepancy. It is recommended you measure and
compare with an accurately measured distance at a location where the precision is speci ﬁcally
monitored on a consistent basis. If such a location is not available, establish your own base line over 20m (when purchasing the instrument) and compare the data measured with the newly purchased instrument.In both cases note that the setup displacement of the instrument position over the point, the prism, baseline precision, poor collimation, atmospheric correction, and correction for refraction and earth curvature determine the inspection precision. Please keep in mind these points.Also, when providing a base line in a building, please note that differences in temperature greatly affect the length measured.If a difference of 5mm or over is the result from the comparative measurement, the following procedure as shown below could be used to change the instrument constant.
1) Provide point C on a straight line, connecting straight line AB which is almost level and about 100m
long. Measure straight lines AB, AC and BC.
2) Obtain the instrument constant by repeating 1) above several times.
Instrument constant=AC+BC-AB
3) When there is error between written instrument constant value and calculated value, review the
Section 8.7-How to Set the Instrument Constant Value procedure.
4) Once again, measure at a calibrated baseline and compare with the instrument base line the
length.
5) If using above procedure and no difference is found from the instrument constant at the factory or a
difference of over 5mm is found, contact TOPCON or your TOPCON dealer.A

8-28.2 Checking the Optical Axis
To check if the optical axis of EDM and theodolite are matched, follow the procedure below. It is
especially important to check after adjustment of the eyepiece reticle is carried out.1) Position the Instrument and prism with about 2m apart and face them at each other.
(At this time, the power is ON. )
2) Sight through the eyepiece and focus to the prism. Then center the prism on the cross hairs.
3) Set to the measure mode to distance measurement or set audio.
4) Sight through the eyepiece and focus the (blinking) red light spot by turning the focusing knob in the
direction of in ﬁnity (clockwise). If displacement of the reticle cross hairs is within one- ﬁfth of the
diameter of the round red light spot both vertically and horizontally, adjustment will not be required.
Note: If displacement is more than one- ﬁfth in the above case, and still remains so after rechecking
the original line of sight, the instrument must be adjusted by competent technicians. Please
contact TOPCON or your TOPCON dealer to adjust the instrument.
Note: For checking the optical axis of GTS-600AF series, please contact Topcon or your Topcon
dealer.

8-38.3 Checking/Adjusting the Theodolite Functions
●Pointers on the Adjustment
1) Adjust the eyepiece of the telescope properly prior to any checking operation which involves
sighting through the telescope.Remember to focus properly, with parallax completely eliminated.
2) Carry out the adjustments in the order of item numbers, as the adjustments are dependent one
upon another. Adjustments carried out in the wrong sequence may even nullify previous adjustment.
3) Always conclude adjustments by tightening the adjustment screws securely (but do not tighten them
more than necessary, as you may strip the threads, twist off the screw or place undue stress on the parts).Furthermore, always tighten by revolving in the direction of tightening tension.
4) The attachment screws must also be tightened suf ﬁciently, upon completion of adjustments.
5) Always repeat checking operations after adjustments are made, in order to con ﬁrm results.
●Notes on the Tribrach
Note that the angle measur
ing precision ma y be eff ected directly if the tr ibrach has not been installed
ﬁrmly.
1) If any leveling screw becomes loose and slack or if collimation is unstable due to the looseness of
leveling screws, adjust by tightening the adjusting screws (in 2 places) installed over each leveling screw with a screwdriver
2) If there is any slack between the leveling screws and the base, loosen the set screw of the holding
ring and tighten the holding ring with adjusting pin, until it is properly adjusted. Re-tighten the set
screw on completing the adjustment.

8-48.3.1 Checking /Adjusting the Plate Level
Adjustment is required if the axis of the plate level is not perpendicular to the vertical axis.
●Check
1) Place the plate level parallel to a line running through the centers of two leveling screws, say, A and
B. Use these two leveling screws only and place the bubble in the center of the plate level.
2) Rotate the instrument 180° or 200g around the vertical axis and check bubble movement of the
plate level. If the bubble has been displaced, then proceed with the following adjustment.
●Adjustment
1) Adjust the level adjustment capstan screw, with the accessory adjusting pin and return the bubble
towards the center of the plate level. Correct only one-half of the displacement by this method.
2) Correct the remaining amount of the bubble displacement with the leveling screws.3) Rotate the instrument 180° or 200g around the vertical axis once more and check bubble
movement. If the bubble is still displaced, then repeat the adjustment.
8.3.2 Checking /Adjusting the Circular Level
Adjustment is required if the axis of the circular level is also not perpendicular to the vertical axis.●Check
1) Carefully level the instrument with the plate level only. If the bubble of the circular level is centered
properly, adjustment is not required. Otherwise, proceed with the following adjustment.
●Adjustment
1) Shift the bubble to the center of the circular level, by adjusting three capstan adjustment screws on
the bottom surface of the circular level, with the accessory adjusting pin.Leveling screw APlate level

8-58.3.3 Adjustment of the Vertical Cross-hair
Adjustment is required if the vertical cross-hair is not in a place perpendicular to the horizontal axis of
the telescope ( since it must be possible to use any point on the hair for measuring horizontal angles or running lines).
●Check
1) Set the instrument up the tripod and carefully level it.2) Sight the cross-hairs on a well de ﬁned Point A at a distance of, at least, 50 meters (160ft.) and
clamp horizontal motion.
3) Next swing the telescope vertically using the vertical tangent screw, and check whether the point
travels along the length of the vertical cross-hair.
4) If the point appears to move continuously on the hair, the vertical cross-hair lies in a plane
perpendicular to the horizontal axis ( and adjustment is not required ).
5) However, if the point appears to be displaced from the vertical cross-hair, as the telescope is
swung vertically, then proceed with the following adjustment.
●Adjustment
1) Unscrew the cross-hair adjustment section cover, by revolving it in the counterclockwise direction,
and take it off. This will expose four eyepiece section attachment screws.
2) Loosen all four attachment screws slightly with the accessory screw-drive (while taking note of the
number of revolutions).
Then revolve the eyepiece section so that the vertical cross-hair coincides to Point A’.Finally, re-tighten the four screws by the amount that they were loosened.
3) Check once more and if the point travels the entire length of the vertical cross-hair, further
adjustment is not required.
Note: Perform following adjustment after completing the above adjustment .

8-68.3.4 Collimation of the Instrument
Collimation is required to make the line of sight of the telescope perpendicular to the horizontal axis of
the instrument, otherwise, it will not be possible to extend a straight line by direct means.●Check
1) Set the instrument up with clear
sights of about 50 to 60meters(160 to 200 ft.) on both sides of the instrument.
2) Level the instrument properly with the
plate level.
3) Sight Point A at approximately 50
meters (160 ft.) distance.
4) Loosen the vertical motion clamp
only, and rotate the telescope 180° or 200g around the horizontal axis, so that the telescope is pointed in the opposite direction.
5) Sight Point B, at equal distance as
Point A and tighten the vertical
motion clamp.
6) Loosen the horizontal motion clamp
and rotate the instrument 180° or 200g around the vertical axis. Fix a sight on Point A once more and tighten the horizontal motion clamp.
7) Loosen the vertical motion clamp
only and rotate the telescope 180°or 200g around the horizontal axis once more and ﬁx a sight on Point C,
which should coincide with previous Point B.
8) If Points B and C do not coincide,
adjust in the following manner.
●Adjustment
1) Unscrew the cross-hair adjustment section cover.2) Find Point D at a point between Points C and B, which should
be equal to 1/4th the distance between Points B and C and measured from Point C. This is because the apparent error between Points B and C is four times the actual error sincethe telescope has been reversed twice during the checking operation.
3)Shift the vertical cross-hair line and coincide it with
Point D, by revolving the left and right capstan
adjustment screws with the adjusting pin.Upon completing the adjustment, repeat the checking operation once more.If Points B and C coincide, further adjustment is not required. Otherwise , repeat the adjustment.

17 PRECAUTIONS
17-117 PRECAUTIONS
1) For transportation, hold by the handle or yoke of the instrument. Never hold by the lens barrel as it
can affect the ﬁxing bracket inside and reduce the accuracy of the instrument.
2) Never expose the instrument without a ﬁlter to direct sunlight. It may damage the components
inside the instrument.
3) Never leave the instrument unprotected in high temperature. The temperature inside instrument
may easily reach up to 70°C or above and will reduce the service life.
4) When a high degree of precision is required for measurement, provide shade against direct sunlight
for the instrument and tripod.
5) Any sudden change of temperature to the instrument or prism may result in a reduction of
measuring distance range, i.e. when taking the instrument out from a heated vehicle.
6) When opening the carrying case and taking out the instrument, place the case horizontally, then
open the case.
7) When returning the instrument to its case, be sure to match the white positioning marks provided
with the case and place the instrument with the eyepiece upward.
8) For transportation, provide dampening or a cushion appropriately to avoid sudden shock or
vibration.
9) For cleaning the instrument after use, remove dust using a cleaning brush, then wipe off with a
cloth.
10) For cleaning the lens surface, use a cleaning brush to remove the dust, then use a clean lintless
cotton cloth. Moisten it with alcohol ( or mixture with ether ) to wipe gently in a rotational motion from the center out.
11) Even if any abnormality occurs, never attempt to disassemble or lubricate the instrument yourself.
Always consult with TOPCON or your dealer.
12) To remove the dust on the case, never use thinner or benzine. Use a clean cloth moistened with

APPENDIX
APPENDIX-1APPENDIX
1 Dual Axis Compensation
Inclination of the vertical axis with respect to true vertical will result in incorrectly measured horizontal
angles. The extent of the error in horizontal angle measurement due to axis tilt depends on three factors :
●the amount of the tilt of axis
●the elevation of the target
●the horizontal angle between the direction of till of the vertical axis and the target.
These factors are related by the following formula : Hz
err = V •sinα • tanh
where v = tilt of axis in arcseconds
α = azimuth angle between vert. axis direction and target
h = elevation of target
Hzerr = error in horizontal angle
Example: When the vertical axis is tilted by 30 arcseconds, the target is 10° above the horizon and
rotated 90 in azimuth from the direction of the vertical axis error.
Hzerr = 30" • sinα • tan10°
Hzerr = 30" • 1 • 0 .176326=5.29"
From the above example it can be seen that horizontal angle errors will increase with steeper vertical
sights (tangent will increase as vertical angle increases) and will be at a maximum when the target is at right angles (sin 90°=1) to the direction of the vertical axis error. Errors will be at a minimum when the
sights are nearly horizontal (h=0, tan0=0) and in the same direction as the vertical axis error (
α =0,
sin0=0). Please refer to the table below to see the relationship between axis tilt (v) and elevation (h) and the error in horizontal angles which results from these factors.

APPENDIX
APPENDIX-2It is clear from the table that dual axis compensation has the most bene ﬁt when the elevation
of the target is greater then 30° and the axis is tilted more than 10". The entries indicated in bold in the table show, in fact, that for many common surveying applications i.e. target elevation <30° and axis error <10", virtually no correction would be required. Dual axis compensation is especially suited then for applications where the sights are very steep.
Even though the compensators can correct horizontal angles for vertical axis errors,
it is still important to use care in setting up the instrument.Centering error, for instance, cannot be corrected by the compensators. If the vertical axis is tilted by 1’ with the instrument 1.4meters above the ground, a centering error of approx. 0.4mm will result. The maximum effect of this error at 10m is about 8" of horizontal angle error.
In order to maintain the increased accuracy possible through dual axis compensation, it is
necessary to keep the compensators in proper adjustment.The compensators must agree with the actual level condition of the instrument. Through various environmental stresses, the agreement between the level condition sensed by the compensators and the true level condition of the instrument may be disturbed. In order to reestablish the correct relationship between the compensator and the true level condition of the instrument, it is necessary to carry out the vertical indexing procedure listed on chapter 14.3.6 "Adjustment of vertical Angle 0 Datum". This
adjustment will both reset the vertical index (cause a direct + indirect zenith reading to the same elevation to equal 360°) and zero the level reference for the horizontal compensator. While correct vertical angles can be obtained by averaging direct and indirect reading even when the index is improperly adjusted, the same is not true for horizontal angles. Since the vertical axis error is ﬁxed for a given setup, its effect cannot be removed by averaging two readings.
For this reason, it is extremely important to maintain the vertical indexing adjustment to
insure proper correction of the horizontal angles.

APPENDIX
APPENDIX-32 Precaution when Charging or Storing Batteries
The capacity of battery will be affected and its service life shortened in any of the following cases while
it is recharged, dischrged or stored.1)Recharging
Fig. 1 shows how ambient temperature at recharging is related to charging ef ﬁciency or as affecting
discharge capacity. As seen from the ﬁgure, charging at normal temperature is best, and the
efﬁciency decreases as the temperature rises. It is best, therefore, to always recharge the battery at
normal temperature to obtain full use of battery capacity and enjoy maximum operation per charge. And the service life of your battery will be shortened if it is frequently overcharged or recharged at high temperature.
2)Discharge
Fig. 2 shows discharge temperature characteristics. Discharge characteristics at high temperature are the same as those at normal temperatures. The battery is likely to have reduced discharge capacity as well as lower discharged voltage when discharged at low temperature. And the service life of your battery will be shortened if it is greatly overcharged.
3)Storage
See Fig. 3 for how storing period at different temperature levels is related to the remaining capacity. The battery will lose its capacity as storage temperature rises and the storage period increases. This does not mean, however , that the battery performance is damaged when the battery is stored. The battery, reduced in capacity, will be restored once it is recharged. Always recharge your battery before use. And recharge and discharge the battery 3 or 4 times to restore its capacity if it has been
stored for a long period or at high temperature. Storing at high temperature can adversely affect the
service life of your battery.Your battery has been fully charged before leaving the factory, but its capacity may be affected
considerably when it takes several months to reach you, if it is stored at high temperature area or passes through a high-temperature region. Then, the battery must be recharged and discharged 3~4 times to fully restore its capacity.And the battery should always be stored at normal temperature or lower if it will not be used for any long period. This helps your battery have a longer service life.Note: 0.1C charge means that the battery is recharged with 0.1 -time current as against its
capacity.
Note: 1C discharge means one with 1 -time current over battery capacity.
