Chapter One - Welcome to Infrared
Thermometry

1.1 Introduction

Exergen Corporation, the world's leading manufacturer of
infrared temperature systems, presents the low cost DX
Series™ of hand held infrared thermometers. These dual­purpose systems function as both NIST traceable tempera­ture calibrators and thermal scanning devices. Make fast,
accurate, and reliable temperature measurements using
advanced non-contact IR technology.

Meet your company's product quality conformance needs
with the DX's patented Automatic Emissivity Compensation
System (AECS). In this mode, the unit will provide preci­sion temperature measurements of spot targets, without
knowing the target's emissivity value, and without errors
caused by other sources of incident radiation. Since the
DX is NIST traceable, it can function as a primary tempera­ture calibrator for other temperature measuring devices,
serving your corporate quality instrument calibration pro­grams. Operate the DX in SCAN mode, for thermal scan­ning measurements over a range of target temperatures.
Thermal Scanning is very useful in many applications such
as evaluating insulation, monitoring machinery, and inspect­ing electrical equipment. Or the DX may be operated in the
MAX mode where the highest temperature measured while
monitoring is presented.

This manual provides complete instructions on how to oper­ate and use your DX--to provide fast, accurate, reliable
temperature measurements for your application needs.

1.2 Product Features

Designed for ease of use and measurement flexibility, the
DX features:

• Dual purpose, AECS as well as MAX and SCAN
measurement modes

• Measurement resolution to 0.1 °F or 0.1°C

• Factory calibration for precise results

• A 10 second display reading hold

• Internal self test and error diagnostic codes to insure
proper function

2.2 To Change Display Measurement Units

The DX Models come from the factory displaying tempera­ture in units of Fahrenheit. To display readings in units of
Celsius, perform the following steps:

1. Remove the screw from the underside of the case.

2. Remove the cover, exposing the battery area.

3. Locate the push button switch as shown in the picture.

4. With the unit off (display is blank), push the push but­ton in.

5. Holding the push button in, turn the unit on with the
MEASUREMENT button.
