Checking the calibration
The laser instrument should be checked, like all measure instruments, before use.
The inspection can be carried out most easily by doing a reverse measurement.
Therefore do the following steps:
Set up the instrument onto a stable fixing.
Turn the laser on and let it level.
Mount the receiver in a fixed distance, i.e. at 100’ (30 m), and move it onto the
laser plane (display middle).
Now turn the instrument around each 90° and let the instrument level.
Measure in each case the difference to the first height.
If the deviation is smaller than ±1/16” (± 2mm), the instrument is within the
specification.
In case of larger deviations the instrument has to be calibrated.
Safety information:
Proper use:
The instrument is for aligning in the desired direction and the grade.
The instrument is used with a rechargeable NiMH battery.
The control of the instrument can be done with a radio controlled remote.
The unit may not be suitable for different application and may not function as
intended with non-approved modifications or accessories. Opening the laser or
making any other modifications may adversely affect the intended function.
Danger: The use in an aggressive or explosive environment (especially gas
bearing pipes) is strictly prohibited!
Warning: Never short circuit the battery contacts with any metal parts or
hold the battery under water. In case of a short circuit the battery can get
extremely hot and there is a risk of injury and fire.
Warning: Never try to charge the battery with chargers that are not supplied
from the manufacturer.
