fter connecting VEGAWELL 72 to power supply or after a
voltage recurrence, the instrument carries out a self-check:
l
I nternal check of the electronics
l
4 … 20 mA output jumps to the failure signal
T
he insturment delivers after this run-up period a current of
4 … 20 mA to the cable. The value corresponds to the actual
