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.

The power is poor. The battery should
be recharged or replace
the battery.
(Angle measurement can only be possible, the auto-collimating and distance
measurement can not be possible.)
Measurement is impossible. Need to
recharge or replace the battery.
* Battery power remaining display is omitted in this manual.
Note:
1) The battery operating time will vary depending on the environmental conditions, such as
ambient temperature, charging time, and the number of times charging and discharging
the battery.
2)In low temperature (especially while the heater of display is working), the battery operating
time will shorten to one-half of normal temperature use.
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 to show the general condition for the battery strength. It does not respond
instantly.

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.
• GPT-8000A/8000 series 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” “Dual Axis
Compensation”.
• The display of Vertical or Horizontal angle is unstable when instrument is on an unstable
stage or a windy day. You 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 8 “PARAMETERS SETTING

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-8000Aseries 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. Pinpole 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).

3.1 Automatic Tracking
Measuring the moving target in automatic tracking mode.
• It is possible to perform auto-tracking only in prism mode. When switched to the automatic
tracking mode, it becomes prism mode from NP mode automatically. Moreover, after the end of an
automatic tracking does not return to Non-prism mode.
• The Coarse (10mm) mode is used for the moving target.
• Use a keyboard on the eyepiece side. When the keyboard on the opposition side is used an
error will be displayed to protect a worker from the radiation of the laser.

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.

A proper setting for each parameter are necessary for custom use.
The setting of the parameters can be done in the star key mode.
3.4.1 Setting Items
1) Search Patterns
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.
1) Things like heat haze might interfere with the tracking system in the long distance, near
limit of auto tracking range, in search mode.
2) Reaction by rotating of instrument in search mode is serious. Be sure of each

2) Search Range
The search range is the area to searched for the prism by rotating the telescope and body in
Searching. The Search range is decided from the point where the prism lost, and the values will
be set to plus and minus directions in horizontal and vertical.
Select search pattern first, and set the search range to the selected search pattern. Also it is
enable to set each search pattern separately.
[Example] SEARCH RANGE: 10º in horizontal, 5º in vertical
Setting Search range requires consideration. The items to think about: optical path interrupted by
other objects; collimated point from GPT-8000Aseries 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-8000Aseries 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-8000Aseries and the prism at
the field. Since the tracking speed represents the rotating speed of GPT-8000Aseries, if the
prism’s traveling speed is high, yet the distance of the prism is far from the GPT-8000Aseries, the
tracking speed can be low.
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.

4.2.6 Stake Out (S-O)
The stake out distance is the difference between the measured distance and the preset distance.
Display value = Measured distance -Standard (Preset) distance
The value on the display is the distance in which the rod person must move toward or away from the
instrument. Aminus (-) sign appearing before the stake out distance indicates that the rod person
would move away from the instrument to reach the stake out distance. If the stake out distance is
displayed with no sign, indicating positive (+), the rod person toward the instrument to reach the
stake out distance.
• Stake out operation can be accomplished in any distance measuring mode, horizontal distance
(HD), relative elevation (VD), or slope distance (SD).
