4 OPERATION
4.3.3 K-Factor
Enter the K-factor of the fitting in this menu (min 0.01 ... max 80000). The "Teach in" func-
tion allows to practically detemine the application specific K-factor. The user only needs to
run a known quantity of liquid through the system.
Example: In order to determine a quantity as accurately as possible, fill a tank of 100 litres.
When the message "TEACH YES" appears, press the Enter key to start the measuring pro-
cedure. The message "FILL END" (end of filling) will appear. Then switch on a pump or open
a valve. As soon as the tank is full, switch off the pump or close the valve. Pressing Enter
stops the measurement. Finally enter the measured volume (100 liters). The calculated K-
factor is displayed after validation.
Note: The transmitter uses the last entered or determined K-Factor.

4.3.4 Output current

The measuring range of the flow, corresponding to the 4-20 mA output current is entered
here, i.e. 0 to 180 l/min corresponds to 4-20 mA. The beginning of the measuring range
can be larger than the end of it, i.e. 0 to 180 l/min corresponds to 20...4 mA (inverted out-
put signal).
The settings (unit and decimal place), as selected for the flow indication will apply.
Check the acceptability of max values and minimum difference in §5.3.
