Troubleshooting via Selftest
The selftest is provided for identification of instrument errors and tolerance violations which can not be
corrected with self-calibration of the instrument.
All signal paths are connected and the signal is traced via test points. The selftest checks all possible
hardware settings which are used for the self-calibration with regard to sufficient setting range including
reserves.
