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 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 decreased, or even the instrument is not
able to measure.
●Tripod
The digital level should be mounted on wooden tripod. Metal tripod is lighter
and it’s easy to shake, which will affect the accuracy. Each leg of the tripod
should be fixed well by screws.
●Tribrach
In case the tribrach is installed not properly, the accuracy would be influenced.
Please inspect the adjusting screw on the tribrach frequently and make sure
the central fixing screw is tightened.
●Packing well to avoid the instrument shaked
As an precise instrument, 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 it is powered off and take off the battery.
●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 lens, otherwise the
spare parts inside the instrument may be damaged.
●Avoid a great change on temperature
A great change on instrument temperature would decrease 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.
●Digital Staff
Wear a glove when using a digital staff.
