5.7 Supplementary electronics
You can use the supplementary electronics - second current output to
provided a second measured value.
Both current outputs are passive and need a power supply.

5.8 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
