After VEGASON 63 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:
•
Internal check of the electronics
•
Indication of the instrument type, the firmware as well as the sen-
sor TAGs (sensor designation)
•
Status byte goes briefly to fault value
Then the current measured value will be displayed and the corre-
sponding digital output signal will be outputted to the cable. 1)
