After connecting the instrument to power supply or after a voltage
recurrence, the instrument carries out a self-check for approx. 10 s:
•
Internal check of the electronics
•
Indication of the instrument type, hardware and software version,
measurement loop name on the display or PC
•
Indication of a status message on the display or PC
•
The output signal jumps to the set fault current
Then the actual measured value is outputted to the signal cable. The
value takes already carried out settings, e.g. default setting into ac-
count.
