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 IP66, 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.
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.
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.
Noise from the inside of instrument
When EDM turns on, the sound of motors from inside the instrument body may be
heard. This is normal and does not effect operation of the instrument.

2 PREPARATION FOR MEASUREMENT
2.2Setting 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.
Reference: Leveling and Centering the Instrument
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.
Leveling screw C
Leveling
screw A
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.
Leveling screw B
2 Rotate the instrument 90° (100gon) around its
vertical axis and turn the remaining leveling
screw or C to center the bubble once more.
Leveling screw C

90°
3 Repeat the procedures 1 and 2 for each 90°
(100gon) 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.

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.

It is recommended for safety to charge the battery beforehand or to prepare spare full
charged batteries.
2For general usage of the battery, see Chapter 14 “POWER SOURCE AND CHARGING” .

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 insufficient battery power for the distance mode which
consumes more power than angle mode.

2.5Vertical and Horizontal Angle Tilt Correction
(GPT-2009 has vertical angle tilt correction only.)
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.
