5.9 Switch-on phase

After VEGAFLEX 86 is connected to the bus system, the instrument

carries out a self-test for approx. 30 seconds. The following steps are

carried out:

Internal check of the electronics

Indication of the instrument type, hardware and software version,

measurement loop name on the display or PC

Indication of the status message "F 105 Determine measured

value" on the display or PC

Status byte goes briefly to fault value

As soon as a plausible measured value is found, it is outputted to the

signal cable. The value corresponds to the actual level as well as the

settings already carried out, e.g. factory settings.
