Calibration Steps
Use the following steps when calibrating an input.
Step
Action
1
Find the minimum and maximum range values for your PV input range from Table 5-1.
2
Disconnect the field wiring and find out what equipment you will need to calibrate.
3
Wire the calibrating device to your controller according to the set up wiring instructions
for your particular input (Subsection 5.4)
4
Follow the calibration procedure given for Input #1 or Input #2 (Subsection 5.5).
5.2 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. Instruments with two or more analog inputs will need to have
each input calibrated separately.
Select the Voltage, Current or Resistance equivalents for 0 % and 100 % range values
from Table 5-1. Use these values when calibrating your controller.
