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.
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.
(For further information see the chapter 'BATTERY SYSTEM.')
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.
