E. Trouble shooting
While moving the initial circle of the calibration the software checks for low amplitudes and errors in
the sensor sequence. The calibration process is halted if errors are detected.
1. Low amplitudes
Low amplitudes indicate broken sensors or a bad sensor connection. Please check sensors and
sensor connections. If the error persists even after sensor replacement, the affected channels have to
be tested for hardware errors.
2. Sequence error
During the initial circle the software checks the sequence of maximum amplitudes measured for all
sensors. An error in the sensor sequence can have different causes.
1. Check if the sensors are accidentally swapped as indicated by the message (for example
sensor 9 is connected to channel 10 and vice versa).
2. Check if the affected sensors are mounted correctly in the magazines (see Fig. 4-7). The
maximum amplitude of a badly mounted sensor can deviate from the expected position.
3. Also broken sensors can lead to a sequence error.
3. Bad Calibration factors
In case of bad calibration factors or error messages
- check if the magazines are well placed
- check if the sensors are well placed
- check if there is no defective sensor in use
