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 or external 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.
Do not hold the lower part of display unit
When you take out the instrument from a carrying case, or keep into the case, please hold
the hand grip and base of the instrument. Please do not hold the lower part of the display
unit.
External power source
Use only recommended batteries or external power source. Use of batteries or an external
power source not recommended by us may result in equipment failure.

2 PREPARATION FOR MEASUREMENT
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 14 “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 insufficient battery power for the distance mode which
consumes more power than angle mode.

2.5 Vertical and Horizontal Angle Tilt Correction
(GTS-239N 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.
z GTS-230N compensates both the vertical angle and the horizontal angle readings due to inclination
of the standing axis in the X and Y directions .

Reference: How to Collimate
1 Point 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.)
2 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.
3 Focus the target with the focusing knob.
*If parallax is created between the cross
hairs and the target when viewing
vertically or horizontally while looking
into the telescope, focusing is incorrect or
diopter adjustment is poor. This adversely
affects precision in measurement or survey
Eliminate the parallax by carefully focusing
and using diopter adjustment.
