Function Fct 4.7.1
Choose one of the following:
Inactive Option not required.
Standby This option puts the meter into a standby mode where the tube is still vibrated,
but the outputs are frozen to zero. Can be used for example during a cleaning
process. Meter will resume measurement mode almost instantaneously once
contact is removed.
Stop This option stops the meter vibrating and shuts all the measurements down. When
the contact is removed, the meter will go though its plausibility checks before
resuming measurement mode. This will take a few seconds.
Zero Calib. This option will initiate a zero calibration externally generated via a push button or
a contact from a valve or pump.
Total Reset Will allow the resetting of the totalizer remotely (the option in menu 3.5.3 needs to
be enabled).
Quit errors Allows the acceptance and quitting of errors remotely.
