After VEGASON 65 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.

tings already carried out, e.g. default setting.
