6.1 Overview

6.2 Auxiliary Output Calibration

OUTPUT CALIBRATION MAY REQUIRE ACCESS TO HAZARDOUS LIVE CIRCUITS, AND
SHOULD ONLY BE PERFORMED BY QUALIFIED SERVICE PERSONNEL. MORE THAN
ONE SWITCH MAY BE REQUIRED TO DE-ENERGIZE UNIT BEFORE CALIBRATION.
6.2 Auxiliary Output Calibration
Introduction
Calibrate the controller so that the auxiliary output provides the proper amount of current
over the desired range. The controller can provide an auxiliary current output range of
from 0 mA to 20 mA and can be calibrated at 4 mA for 0 % of output and 20 mA for
100 % of output or any other values between 0 mA and 21 mA.
Equipment Needed
You will need a calibrating device with whatever accuracy is required, capable of
measuring 0 to 20 mA.
Calibrator Connections
Refer to Figure 6-1 and wire the controller according to the procedure given in Table 6-1.
