5.7 Switch-on phase

After connecting the instrument to power 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 or PC

Indication of the status message "F 105 Determine measured

value" on the display or PC

The output signal jumps to the set error current

As soon as a plausible measured value is found, the corresponding

current is outputted to the signal cable. The value corresponds to the

actual level as well as the settings already carried out, e.g. factory

setting.
