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-

A2xxOperation and handling

surement, which is why a correct angle calculation on curved workpieces
and within the bending radius (important for workpieces with obtuse angles)
is not possible.
The measurement range lies between 30° and 150°.
1 ... Measurement range
For practical use of the measurement device, be aware that the surfaces of
the workpiece scanned by the laser along with its respective reflective prop-
erties form a functional part of the overall measurement system and thus in-
fluence the actually achievable accuracy. The achievable accuracy is also
affected by proper handling of the measurement device as well as by the en-
vironmental conditions; also refer to Chapter "Technical data".
The following influencing factors can affect measurement precision and re-
peat accuracy and must be taken into consideration:
Influencing factor Description
Alignment of the device to the
workpiece
The longitudinal axis of the housing of KeMes A2xx must
be aligned parallel to the bending edge and tilted as little as
possible in order to be symmetrical between the two legs of
the workpiece. Observe a minimum distance of 20 mm be-
tween the mirror and the workpiece surface. The measured
distance to both legs should be equal if possible.
Poor planarity Unevenness on the surface of the leg being measured
must be prevented.
Non-homogeneity of the reflec-
tive properties
Different, uneven reflective properties of the legs being
measured on the test specimen (e.g. dirt, scratches, coat-
ing, discoloration, oils, welding chips, patches of corrosion,
etc.) must be prevented. If necessary, the test piece must
be cleaned, or the selection of the measurement field must
be changed.
Dirt Dirt on mirror and lens of the device must be prevented.
Vibrations
If a measurement takes place on a machine, the legs of
thin sheets have the tendency to vibrate or reverberate
when relaxing. Make sure that the sheet metal legs do not
vibrate during the measurement operation.
