Minimum and Maximum Range Values
Select the Range Values
Calibrate the controller for the minimum (0 %) and maximum
(100%) range values of your particular input type. Two input
controllers will need to have each input calibrated separately.
Select the Voltage, Current or Resistance equivalents for 0 % and
100 % range values from table below. Use these values when
calibrating your controller.
