tions and keep them in a convenient location for future reference.
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.

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.

Heavy shocks may cause the measurement to be faulty.

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

instrument acclimate itself to ambient temperature.
