5.8 Switch on pha

After VEGABAR 64 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.

The values correspond to the actual measured level as well as to the set-

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