General notes
Compare the current raw data with that from the last service (service printout).
Error messages in fields 3 and 4 suggest a fault in the hardware.
Check the pneumatic components unit, cables etc. before sending the measuring
instrument unit back to the works.
Observe the initial response of the gain factors (field 9).
If the target values are not reached, this suggests a fault in the hardware.
Remember that the instrument must be switched on for at
least 30 minutes before the calibration.
If the measuring instrument unit develops a fault and has to
be returned to the works, always include a "service printout"
to assist the error diagnosis.
