The following input options are available:
● Start dosing
● Hold / continue dosing
– When this function is activated, it will pause the dosing. When it is deactivated, the
dosing will continue
● Stop dosing
– Sets the digital output to "Off" and resets the dosing counter
● Zero adjust
– Starts the automatic zero point adjustment. This function employs the existing
configurations and presumes that the process conditions are prepared for the zero point
adjustment routine
● Reset totalizer
– Resets one of the internal totalizers 1, 2 or 3 (depending on configuration)
● Resets all totalizers simultaneously
● Freeze signal
– Freezes all currently measured values in the display and outputs
● Force signal
– Forces all outputs to adopt the value selected in the menu. If the value 100% is selected,
the current output will show 20 mA and the frequency output will show 10.000 kHz when
the external output is activated
WARNING
Changing polarity
Changing the polarity triggers the signal input to execute the set functionality.

Totalizers
Totalizer functions
The device has three independent totalizers that can be used to total the massflow, volumeflow,
corrected volumeflow, fraction A (volumeflow or massflow) or fraction B (volumeflow or
massflow).
The totalizers can be configured to count balance (net flow), positive flow or negative flow.
In case of failure in the system, the totalizer fail safe mode can be set to:
- Hold (default): the totalizer holds the last value before the failure occurred
- Run: the totalizer continues counting the actual measured value
