Adjust 4 ma: 250
The number on the second row is the setpoint of the 4 mA output. It is
analogous to a potentiometer wiper. The number can be set anywhere from 0
to 500. The default is 250, in the middle. At the default setting, the output
should be very close to 4 mA. If not, slowly adjust the number using the Up or
the Down keys until DMM reads 4.00 mA. Enter when done.
5. A screen similar to the one above will appear and the DMM
should read close to 20 mA. If not, slowly adjust the number using the Up or
Down key until DMM reads 20.0 mA. Enter when done to return to system
menu.
The range of adjustment is approximately +/- 10% of scale (+/- 1.6 ma).
Since the 4 to 20 mA output is tied to the 0 to 1 volt output, this function can be
used to calibrate the 0 to 1 volt output, if the 4 to 20 mA output is not used. By
using a digital Volt meter on the 0-1 Volt output.
3.3.12 Manual control of filter and solenoids
