a value between 0 and 4095

Lower Display

ZERO VAL

until the desired 0 % output is read on the milliammeter. Use the values shown below depending on the action of your valve.

0 mA	For 0 to 20 mA Direct Action *
20 mA	For 0 to 20 mA Reverse Action
4 mA	For 4 to 20 mA Direct Action
20 mA	For 4 to 20 mA Reverse Action

This stores the 0 % value and you will see:

Upper Display

a value

Lower Display

SPAN VAL

until the desired 100 % output is read on the milliammeter. Use the values shown below depending on the action of your valve.

20 mA	For 0 to 20 mA Direct Action
0 mA	For 0 to 20 mA Reverse Action*
20 mA	For 4 to 20 mA Direct Action
4 mA	For 4 to 20 mA Reverse Action

The controller will store the span value.

*When attempting to achieve 0 mA, always adjust the output to about 0.5 mA, and slowly decrease until the output just goes to zero. Further decrementing will not change the output current (since the circuit cannot produce negative current) but will affect the accuracy of the output by creating a dead zone where no current flows.
