After VEGAPULS 66 is connected to voltage supply or after voltage
recurrence, the instrument carries out a self-check for approx. 30
seconds. The following steps are carried out:
l Internal check of the electronics
l Indication of the instrument type, the firmware as well as the
sensor TAGs (sensor designation)
l Status byte goes briefly to fault value
Then the current measured value will be displayed and the
corresponding digital output signal will be outputted to the cable.
