20mA Output Value
Set the CL output value according
to the flow value at 20mA. the flow
unit is the same as that found in
Window m31. Once "4-20mA vs.
Vel." is selected in Window M57,
the unit should be set as m/s.
CL Check Verification
Check if the current loop has
been calibrated before leaving
the factory. Press
to start,
press
or
to display 0mA,
4mA, 8mA, 12mA, 16mA,20mA, and at
the same time, check with an ammeter
to measure the current loop output
current and calculate the differences to
see if it is under the permitted
tolerance.If not, refer to the "Analog
Output Calibration" to calibrate.
CL Current Output
Display CL current output. The
display of 10.0000mA indicates that
CL current output value is
10.0000mA. If the difference
between displaying value and CL
CL 20mA Output Value
