5.8 Switch-on phase
After connecting the instrument to power supply or after a voltage
recurrence, the instrument carries out a self-check for approx. 10 s:
•
Internal check of the electronics
•
Indication of the instrument type, hardware and software version,
measurement loop name on the display or PC
•
Indication of a status message on the display or PC
The duration of the warm-up phase depends on the connected sen-
sor.
Then the actual measured value is displayed. You can find further
information on the display in chapter "
Measured value indication -
