Operating hours counter

You can read out one operating hours counter for the electronics and one for the sensor.
They are activated upon first commissioning of the pressure transmitter.

Calibration interval and service interval

There are two timers in the pressure transmitter:
● A timer for the calibration interval, which ensures regular calibration of the electronics.
● A timer for the service interval, which draws attention to any necessary service for the
sensor cell and its connections.
The interval is selectable. The timers can monitor on two levels, first giving a warning, then
an alarm.
