If the result is ***FAILED***, the service technician should pay attention not
only to the entries marked with FAILED** but also to those marked with
SKIPPED. These entries indicate that a test item was not performed because
the preconditions were not observed. In that case, it is an error only if it was
also not possible to calibrate the instrument.
The selftest with a password yields FAILED as the overall status, as it will
relatively soon no longer be possible to calibrate the instrument due to a
temperature drift or aging.
The selftest without a password yields PASSED as the overall status; here
too, however, the skipped test items are marked with SKIPPED as an
indication for the service technician.
