9.7.2. Adjusting the spAn of the current output
This parameter makes it possible to adjust the 20 mA current value transmitted on the 4-20 mA output.
→
Connect a multimeter into the measurement loop.
→
The device generates a 20 mA current.
→
Measure the current given on the 4-20 mA output using a
multimeter.
→
Enter the value displayed by the multimeter. The permitted span
range is 15 to 21,50 mA.
→
Confirm.

9.7.4. checking the outputs behaviour
This parameter makes it possible to simulate a flow rate in order to check that the outputs are behaving as expected by the
configuration made.
→
Enter a flow rate value, in the unit chosen in the "UNIT" parameter.
→
Confirm by pressing the
ENTER
key. the display returns on the
"FLOW" parameter.
→
Check that the outputs are behaving as expected.
