Analog Output Source
The analog output source can be based on either of the input channels
(Ch-A, Ch-V), the power channel (Ch-P), maximum stored value of
either input channel (Hi-A, Hi-V), minimum stored value of either input
channel (Lo-A, Lo-V), relay set points, or the Modbus input.
Analog Output Calibration
To perform the analog output calibration it is recommended to use a
milliamp meter with a resolution of at least 0.1 µA to measure the output
current. The values saved internally during this procedure are used for
scaling the 4-20 mA output in the Setup menu.
