7.13 4mA Adjustment
If the 4-20 mA setting is turned ON (7.1 Setting the 4-20 mA Output), the following two
menus will appear. The first menu outputs a constant 4 mA while allowing for a small
amount of adjustment. The adjustment can be made using the  and  buttons. This
adjustment will allow the operator to make the CLX agree with a PLC or SCADA system.
The adjustment limits are ± 200 counts or about ± 0.2 mA.
This setting will be slightly different on each instrument as each CLX will be factory set
to 4.00mA. Press the
↵ button when adjustments are complete to save this setting and
move on to the 20mA adjustment.
7.14 20mA Adjustment
This menu operates similar to the previous menu. This menu outputs a constant 20 mA
while allowing for a small amount of adjustment. The adjustment can be made using the
 and  buttons. The adjustment limits are ± 1000 counts or about ± 1 mA.
This setting will be slightly different on each instrument as each CLX will be factory set
to 20.00mA.
When complete with the 20mA adjustment, press the
↵ button to exit to AUTO mode and
save all configuration settings .
