Thank you for purchasing the TOPCON Auto Tracking Total Station, GTS-820A
series. For the best performance of the instruments, please carefully read these
instructions 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 submerge the instrument into water.
The instrument can not be submerged underwater.
The instrument is designed based on the International Standard IP54, therefore it is protected from
the normal rainfall.
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.
TR-5 or TR-5P tribrach should be used for prism side when the traverse surveys is performed.
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, “Back up battery
empty” will display. It is still possible to measure the distance and the angle, but the measured data
and the parameter setting can be lost. 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.
No responsibility
TOPCON Corporation has no responsibility for loss of data stored in the memory in case unexpected
accidents.

Rotating the instrument and telescope
Rotation of the instrument or telescope is driven electronically in normal operation.
Do not disturb the rotation.
Storage in the case
Keep the telescope horizontally and turn the instrument to align its mark with the lower base mark
(Storage mark). Keep its objective lens side downward. Storing it in the case in any other way may
cause damage. Hold the hand grips and base with both hands, when taking the instrument out of the
case, or putting the equipment in the case.

device, the measured data will be output by GTS-820A series. Select from the following
2 ways for the output. (For setting, see Chapter 8 “PARAMETERS SETTING MODE” .)
REC-A : The measurement is started and new data is output.
REC-B : The data being displayed is output.
1.8 Rotating Method
1.8.1 Rotating by H/V Shuttle and H/V Jog
H/V shuttle or H/V jog can be used to rotate the instrument manually. The shuttle movement or
displacement is proportional in speed and size of angle desired. A small, slow turn of the shuttle will
result in a slow small angle displaced. Likewise, a larger abrupt turn of the shuttle will result in a coarse
angle displacement. H/V jog can be used for accurate collimating of the target much like a standard
tangent screw.
1.8.2 Auto Inversion
Pressing the [F4] key in Star Key mode causes the instrument to reverse and turn the telescope and
instrument automatically.
l To stop auto rotating by auto inversion key in case of emergency, press any keys except POWER
key.
l During auto rotation, don't disturb the instrument.(Stopping the rotation with a touch of the hand).
Such action may cause trouble or harm to instrument or operator.
See Section 1.5 “Star key (*key) mode” for further instructions.
1.8.3 Rotating automatically to a required Horizontal and Vertical angle
In Standard Measurement Modes, the instrument can be rotated automatically by input a required
horizontal and/or vertical angle.
For further instructions, see Section 4.1.5 “Automatic Rotation to a Required Horizontal and Vertical
Absolute Angle” .
This mark will appear while the

3) The indicator for battery power remaining shows the power level during each measurement
mode. The condition indicated for the battery power remaining in the angle measurement
mode may not be adequate to measure a distance. Changing from angle mode to distance
mode during a poor battery condition may cause the EDM not to measure a distance.
We recommend that you check the battery condition before going into the field.
4) Also note, when changing from one measurement mode to another, the battery indicator may
not show a decrease or an increase immediately. The battery indicator system was designed

2.11 Inclination of Prism and Measuring Error
For the best results, aim or point prisms in the direction of the GTS-820A series so that maximum signal
can be returned to the instrument. Sighting prism obliquely because of inclined settings, may result in
measuring errors. These errors will be proportional to the misalignment as showing in following graphs.
The more misalignment of the prism, the more error in measurement.
Measured data can be different according to the prism constant value. This can occur when a prism is
moving. Pin-pole prism set L1 (for one-person surveying) and pin-pole prism holder L1 (for fixed point
observation) are designed to minimize measuring error in such case. Make the best use of them. In
case you are forced to use the normal prism in inclined state because there is no other way possible,
we recommend to use switching holder, prism constant value (0 or 30mm), and set to 30mm
(Compensation value of -30mm).

3.3 Range of Laser for Auto-tracking and Auto-collimating
The range of laser at the long distance is within ±30' as shown in following. So you had better collimate
the prism so that the prism may be located within this range of laser in the first step. As for it, rapid
automatic collimating and automatic tracking becomes possible. If the target prism is out of this range,
time for searching mode will be necessary.
Field of view

The search pattern is the rotating method of telescope and instrument to find the target prism in search
mode. Search pattern includes the following 2 ways that can be selected.
PATTERN 1
This pattern can be selected to search the prism at the point where the prism is lost.
Instrument searches in up down direction gradually from the point where the prism is lost.
The searching is arranged to 2 times until the prism is found.
The auto tracking mode changes to manual mode when the reflector could not found out
within 2 times searching, and returns to the point where the reflector is lost.
PATTERN 2
This pattern can be selected to search for the prism. The search pattern tries to locate the
prism in a very short time.
The searching is arranged to 2 times until the reflector is found.
The auto tracking mode changes to manual mode when the reflector could not found out
within 2 times searching, and returns to the point where the reflector is lost.
1) Things like heat haze might interfere with the tracking system in the long distance, near limit of auto

When beginning auto-tracking, the instrument needs to collimate stable prism.
Suitable for controlling of construction machinery or real time surveying of variety
traveling objects.
When beginning auto-tracking, the instrument can track a prism, even if the prism is
moving.
Note: If the Machine Control mode is chosen, the GTS-820A may incorrect-track the headlight of a car
etc. temporarily.
5) Reflector type
You can choose a reflector type according to reflective objects such as Prism-2 or reflector tape.
This setting will reduce incorrect tracking.
6) Prediction operating time
After the instrument loses a prism, the time (prediction operation time) for the instrument to continue
moving operation can be set up.
During auto tracking operation, when auto tracking axis between the instrument and a prism is
intercepted by a tree etc., the moving is continued supposing a motion (prediction) of the prism till then.
It is effective in auto tracking operation after the prism is intercepted with the obstacle by this function.
When an obstacle is large, the prediction operation time should be set up long.
Moreover, when you want to terminate auto tracking operation immediately at the point which missed
the prism, and to be changed into a search state. Prediction operation time should be set up short.

This mode is useful when it is difficult to set up the prism directly, for example at the center of a tree.
Place the prism at the same horizontal distance from the instrument as that of point A0 to measure.
To measure the coordinates of the center position, operate the offset measurement after setting the
instrument height/prism height.
When measuring coordinates of ground point A1
:Set the instrument height/prism height.
When measuring coordinates of point A 0 : Set
the instrument height only. (Set the prism height
to 0 ).

When sighting to A0, you can select one of two
ways. [HOLD] is to fix vertical angle to the prism
position even updown the telescope position, and
[FREE] is to gear vertical angle to the updown of

CHECK AND ADJUSTMENT
9.1 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 specifically
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 with the data measured with 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 the difference in temperature greatly
changes the length measured in the building.
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 horizontal and about
100m long, and measure straight lines AB, AC and BC.
B
A
C
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 9.7 “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.

4) Turn the horizontal jog counterclockwise slowly, move the collimating point to the left side of prism
gradually until buzzer sound stops.
5) Turn the horizontal jog clockwise slowly, and move the collimating point to the prism center
gradually until at the position buzzer starts.
Confirm the level of the signal (light quantity level) in display to adjust at the level of one to two as
shown in below by turning the horizontal jog.
Quantity level one
Quantity level two
6) Press the [ESC] key and measure the horizontal angle, and note the horizontal angle displayed. Or
you can do 0-set of horizontal angle.
7) Return to the Set Audio in star key again.
8) Turn the horizontal jog clockwise, move the collimating point to the right side of prism gradually until
buzzer sound stops.
9) Move the collimating point to the center of prism gradually until buzzer sound starts.
Turning the horizontal jog to be one to two level of SIG value to adjust the collimating point same as
5) procedure.
10) Note horizontal angle same as 6) procedure.
11) Calculate the average value of 6) and 10).

9.3 Checking/Adjusting the Theodolite Functions
l 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 sufficiently, upon completion of adjustments.
5) Always repeat checking operations after adjustments are made, in order to confirm results.
l Notes on the Tribrach
Note that the angle measuring precision may be effected directly if the tribrach has not been installed
firmly.
1) 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.

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.

l 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.

9.3.3 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
vertically running lines).
l Check
1) Set the instrument on the tripod and carefully level it.
2) Sight the cross-hairs on a well defined Point A at a distance of, at least, 50 meters (160ft.).
3) Next swing the telescope vertically using the jog/shuttle, 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, adjustment is required in the reticle plate.
l 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.

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.
Telescope
4) 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.
6) Rotate the instrument 180° or 200g
around the vertical axis. Fix a sight
on Point A once more.
7) 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.
l 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 since
the 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.

9.3.5 Checking / Adjusting the Optical Plummet Telescope
Adjustment is required to make the line of sight of the optical plummet telescope coincide with the
vertical axis (otherwise the vertical axis will not be in the true vertical above the reference point when
the instrument is optically plumbed).
l Check
1) Coincide the center mark and the point. (See Chapter 2 “PREPARATION FOR MEASUREMENT”.)
2) Rotate the instrument 180° or 200g around the vertical axis and check the center mark.
If the point is properly centered in the center mark, adjustment is not required. Otherwise, adjust in
the following manner.
l Adjustment
1) Take off the adjustment section cover of the optical plummet telescope eyepiece. This will expose
four capstan adjustment screws which should be adjusted with the accessory adjusting pin to shift
the center mark to the point. However, correct only one-half of the displacement in this manner.

17 PRECAUTIONS
17
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
neutral detergent.
13) Check each part of the tripod after extended use. Parts (screws or clamps) may work themselves
free.

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 :
l
l
l
the amount of the tilt of axis
the elevation of the target
the horizontal angle between the direction of tilt of the vertical axis and the target.
These factors are related by the following formula :
Hzerr = V•sin α • tanh
where v = tilt of axis in arcseconds
α = azimuth angle between vert. axis direction and target
h = elevation of target
Hz err = 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.
Hz err = 30" • sinα • tan10°
Hz err = 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-1
APPENDIX
It is clear from the table that dual axis compensation has the most benefit 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 Section 9.4“Adjustment of Compensation Systematic Error of
Instrument” . 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.

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, discharged or stored.
1) Recharging
Fig. 1 shows how ambient temperature at recharging is related to charging efficiency 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.
Note: 0.1C charge means that the battery is recharged with 0.1 -time current as against its
capacity.
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.
Note: 1C discharge means one with 1 -time current over battery capacity.
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.
