Action
If the signs are different, subtract the lower measured value from the higher value and enter
the result in column 3. Enter the sign of the higher value in column 3.
If the signs are the same, add the measured values together and enter the result with sign in
column 3.
If the signs are the same, subtract the low measured value from the high value and enter the
result in column 3. If the higher measured value is in column 1, the sign is adopted. If the
higher measured value is in column 2, the sign changes.
If the signs are different, add the measured values together and enter the result in column 3.
Enter the sign from column 1 in column 3.
If the signs are different, add the measured values together and enter the result in column 4.
If the signs are the same, subtract the lower measured value from the higher value and enter
the result in column 4.
If the signs are different, subtract the lower measured value from the higher value and enter
the result in column 4.
If the signs are the same, add the measured values together and enter the result in column 4.
The values in column 4 should not be higher than 3'. If they are, measurement errors have been
made, e.g. changes to vehicle or quick-action clamps.
The measurement must be repeated.
The measured values in column 3 must not be higher than 6'. In the event of a greater
difference, the unit must be re-adjusted. The Service department should then be consulted.
Possible cause
Mechanical damage to sensor,
sensor incorrectly adjusted.
Obstacle between opposing
cameras of sensors.

Sensor not connected (cable operation).
Link with communication processor in
measurement box being re-established.
No link between computer and communication
processor (measurement box).
Incorrect mains voltage.
Program crash.
Communication processor defective.
