Input Calibration; Overview - Honeywell UDC3500 Product Manual

INPUT 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.

5.1 Overview

Introduction
This section describes the field calibration procedures for Analog Inputs 1 through 5.
• All input actuations in every controller are fully factory-calibrated and are ready for
configuration by the user.
• Field Calibration can improve the accuracy of the Controller if necessary for a
particular application.
CAUTION
The field calibration will be lost if a change in input type configuration is implemented at a later
time. The original factory calibration data remains available for later use after a field calibration
is done. See Section 5.6 if you want to restore factory calibration values.
