4 OPERATION

4.3.3 K-Factor

The K-Factor of the fitting is entered in this menu (see manual of fitting S020/1500/1501).
The "Teach in" function allows to practically detemine the application specific K-Factor.
The user only needs to run a known quantity through his system.
Example: In order to determine a quantity the most accurately possible, the user shall fill
a tank of 100 liters. When the message "TEACH YES" appears, he presses the Enter key to
start the measuring procedure. The message "FILL END" (end of filling) will appear. He then
switches on a pump or opens a valve. As soon as his tank is full, he switches off the pump
or closes the valve. Pressing Enter stops the measurement. The user will then be asked
to enter the quantity (100 liters). The calculated K-Factor is displayed after confimation.
Note: The device uses the K-Factor entered or determined at last.

4.3.4 Output current

The measuring range of the flow, corresponding to the 4...20 mA output current is entered
here. E.g. 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 output
signal).
The settings (unit and decimal place), as selected for the flow indication will apply.
