5.5 Switch-on phase
After connecting the instrument to voltage supply or after a voltage
recurrence, the instrument carries out a self-check for approx. 30 s:
•
Internal check of the electronics
•
Indication of the instrument type, hardware and software version,
measurement loop name on the display
•
Indication of the status message "
F 105 Determine measured
value
" on the display
•
The output signal jumps to the set fault current
As soon as a plausible measured value is found, the corresponding
current is output to the signal cable. The value corresponds to the
actual level as well as the settings already carried out, e.g. factory
setting.
