After VEGAPULS 62 is connected to the bus system, the instrument
carries out a self-test for approx. 30 seconds. The following steps are
carried out:
l Internal check of the electronics
l Indication of the instrument type, hardware and software version,
measurement loop name on the display or PC
l Indication of the status message "F 105 Determine measured
value" on the display or PC
l 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.
