There are two signal system:0 to 10mA and 4 to 20mA, it can be selected from parameter se ng.
Simula on signal output inner is 24V for 0 to 20mA, it can drive
750Ω
resistance.
The percent flux of simulation signal output:

For example ;
Measuring Value : 168 m3/h
Full Scale : 200 m3/h Current Range : 20 – 4 mA : 16 mA I
0
: 4 mA
(168/200)x16+4 :
17,44 mA
Current – Zero Point Calibra on
Enter “Parameter Se ng”, and select “Analog Zero”. The standard of signal fountain ge ng to “0”. Adjust
parameter to ensure that the value of Amperometer is 4mA (±0.004mA).
Current – Full Scale Calibra on
Enter “Anlg Range”. Adjust parameter to ensure that the value of Amperometer is 20mA (±0.004mA)
