Input and Output Calibration for Recorder with Display

5.Input and Output Calibration for Recorder with Display

5.1Overview

Introduction

This section explains how to field calibrate analog inputs, as well as a 4 to 20 mA current output for a model having a display and keypad.

Because the recorder stores both factory and field calibration values for inputs in memory, you can easily select either factory or field calibration values for use by the recorder using the procedure given in Subsection 4.5.2.5.

To calibrate an input:

•Determine the minimum and maximum range values to be used for calibration (see Subsection 5.2).

•Prepare to calibrate (see Subsection 5.3).

•Set up and wire the input for calibration (see Subsection 5.4).

•Use the parameters in the calibration set up group to store field calibration values in the recorder’s memory (see Subsection 5.5).
