5 Operation and handling
5.1 General instructions
Caution
Damage to property due to severe vibrations
Severe vibrations of the device (e.g. if the device drops to the ground) may
damage the electronics and the precision measurement unit or destroy the
device.
In any case, verification of the measurement results is required afterward,
e.g. using a reference angle.
If the device is damaged, the device must no longer be used and must be
sent to our service partner for repair.
Caution
Condensation of humidity in the device
● Do not expose the device to high humidity for an extended period of
time.
● If a cold device is brought into a significantly warmer environment (e.g.
after extended transport in a cold environment), condensation moisture
may form in the device. Before using the device, you must wait until the
temperature of the device is the same as the room temperature and the
moisture has evaporated.
5.2 Measurement principle and measurement accuracy
During measurement, the laser beam is directed outward by a mirror. The
laser beam is visible to the observer as a thin line on the workpiece. The
beam must be capable of hitting the two legs being measured at an angle of
90°.
If the laser beam is not reflected on the metal sheet surface at an angle of
90°, no measurement is possible. For this reason, it is possible that work-
pieces with bores or recesses cannot be measured. Faulty measurements
caused by reflections in the room cannot be ruled out either. If the beam
misses the legs, the distance between the device and the bending edge
must be reduced.
The laser beam is displayed more brightly in the area of 90° to the leg.
These areas are called measurement fields. Thus, users can identify during
measurement where the exact measurement position is, allowing them to
modify the position of the device as necessary. Note that this is a point mea-
