A fter connecting VEGABAR 52 to power supply or after a voltage
recurrence, the instrument carries out a self-check for approx. 30
seconds:
l I nternal check of the electronics
l I ndication of the instrument type, the firmware as well as the
sensor TAGs (sensor designation)
l O utput signal jumps briefly (approx. 10 seconds) to the set fault

T hen the corresponding current is outputted to the cable (the value
