PRECAUTIONS
Before using this instrument, please make sure that each function is running well.
●
Avoid to make the surface of the digital staff as well as the joints between each
section dirty or damaged, otherwise it will influence on the accuracy of reading and
measurement. This is because the instrument needs to transfer the black & white bar
code to electric signal. That’s why in case the digital staff is dirty, the accuracy would
be descended, or even the instrument is not able to measure.
●
Tripod
The digital level should be mounted on wooden tripod. Metal tripod is lighter and
shack easily, which will affect the accuracy. Each leg of the tripod should be fixed well
by screws.
●
Tribrach
Please check the adjusting screw on the tribrach frequently, do make sure the central
fixing screw is tightened.
●
Packing well to avoid the instrument shaked
The digital level should be handled carefully to avoid shaking and crashing during
transportation. Severe shaking would damage the measurement functions. When
packing the instrument in the case, make sure the instrument is power off and take off
the battery too.
●
Carry the instrument carefully
When you need to move the instrument, you must grasp the lifting handle and take it
off from the tripod.
●
Avoid to expose the instrument in sun, rain or humid condition
Leaving the instrument in place of high temperature (+50
℃
) would damage the
instrument. Do not shoot the sun with the objective len; otherwise the spare parts
inside the instrument may be damaged.
●
Avoid the great change of temperature
A great change on instrument temperature would descend the measuring range. For
example, when the instrument is moved out from a hot car, please leave the
instrument to adapt to the surrounding temperature before use.
●
Battery Inspection
Check the remaining battery before use.
