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, “Back up battery
empty” 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.
No responsibility
TOPCON Corporation has no responsibility for loss of data stored in the memory in case unexpected
accidents.

2.11 Inclination of Prism and Measuring Error (GPT-8000A series)
For the best results, aim or point prisms in the direction of the GPT-8000A 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).

● Cause eye injury or blindness.
Do not stare into beam.
CAUTION
e
● Let the laser beam reach the aimed object or the target without anybody else in the laser beam path. In
case you operate laser beam open, avoid radiating laser beam to the height of man's head. It is quite
possible for the beam to enter into one's eyes, and it is possible to lose visual sight temporarily, and lose
one's caution and awareness of other dangers - avoid glaring beam.(GPT-8000A series)

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.

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
PATTERN 2
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 refrector could not found out
within 2 times searching, and returns to the point where the refrector is lost.
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 refrector is found.
The auto tracking mode changes to manual mode when the refrector could not found out
within 2 times searching, and returns to the point where the refrector is lost.
1) Things like heat haze might interfere with the tracking system in the long distance, near limit of auto

Setting Search range requires consideration. The items to think about: optical path interrupted by other
objects; collimated point from GPT-8000A series to prism is shifted after Turning and Searching
Command; possible other prisms, targets, or other objects to interfere with tracking the desired prism;
and many other examples all play a role in determining the search range.
Note: This search range is only for auto-tracking function. The search range of auto-collimating is fixed
as ±5° in both directions horizontal and vertical.
3) Wait Time
The time the prism is lost before GPT-8000A series starts the searching. Setting time is 1second step
maximum 60 minutes.
If the mode is set to [HOLD], mode will not change to searching.
4) Tracking Speed
The tracking accuracy (aiming accuracy) shall be determined in the best condition by the relationship of
moving speed of the prism and the distance between GPT-8000A series and the prism at the field.
Since the tracking speed represents the rotating speed of GPT-8000A series, if the prism’s traveling
speed is high, yet the distance of the prism is far from the GPT-8000A series, the tracking speed can be
low.

Aim 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.
Focus the target with the focusing knob.
*If parallax is created between the cross
hairs and the target when viewing

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 A0 : Set
the instrument height only. (Set the prism height
to 0 ).

Measuring will be taken for the place where direct measuring can not be done, for example distance or
coordinate measuring for a edge of a plane.
Three random target points (P1, P2, P3) on a plane will be measured at first in the plane offset
measurement to determine the measured plane. Collimate the measuring target point (P0) then the
instrument calculates and displays coordinate and distance value of cross point between collimation
axis and of the plane.

9.1
Checking and Adjusting of Instrument Constant
Note: Each of the Prism mode and Non-prism mode has instrument constant.
You must obtain the instrument constant of prism mode. If you reset the instrument
constant of the prism mode, you must vary the non-prism constant (Non-prism-short, Nonprism-long) by the same quantity as the amount of increase or decrease of the instrument
constant of the prism mode.

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.
9.1.1 Checking of the accuracy of the non-prism mode
If you reset the instrument constant, you must check the accuracy of the non-prism mode.
1) Set a prism 30 to 50 meter apart from the instrument and measure the distance to the prism by
prism mode.
2) Take off the prism and set a (white) board.
3) Change the mode to the non-prism mode and measure the distance to the board.
4) Repeat above procedure and measure some points.
If the difference of the prism mode and non-prism mode is the range of ±10mm even one time, the
instrument is normal.
If the difference is never the range of ±10mm, contact TOPCON or your TOPCON dealer.

9.2 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 a prism about more than 150 m apart from GPT-8000A/8000 series.
2) After the power switch ON of GPT-8000A/8000 series, collimate the center of the prism.

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

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).
● 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.
● 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.

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.
● 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.

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).
● 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.
● 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.

Recharging should take place in a room with an ambient temperature range of 10°C to
40°C (50°F to 104°F).
If charging is done at high temperature, charging time of the battery may take longer.
Exceeding the specified charging time may shorten the life of the battery and should be
avoided if possible.
The battery source will discharge when stored and should be checked before using with
instrument .
Be sure to charge as stored battery source every 3 or 4 months and store in a place at
30°C and below when it will not used for a long period.
If you allow the battery to be completely discharged, it will have an effect on the overall
performance for proper charging in the future.
Keep batteries charged at all times.

APPENDIX
APPENDIX
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 tilt of the vertical axis and the target.
These factors are related by the following formula :
Hzerr = V•sin α • tanh
e
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-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.
e
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.
