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

5.6 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
