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.
DX 1601 0 to 1600°F (86 to 871°C) Unit includes a Remote Sensor, 9 V DC Alkaline Battery and DX Instruction Manual. Also available with an RS232 Digital Output and an Analog Output. Chapter Two - Operation 2.
The instrument now reads in °C instead of °F. To return to the original setting, simply repeat the process. ºF/ºC Switch MAX/SCAN Switch 2.3 To Change Mode of Operation The DX Models come from the factory operating in the MAX mode. To change to the SCAN mode perform the following steps: 1. 2. 3. 4. Remove the screw from the underside of the case. Remove the cover, exposing the battery area. Locate the slide switch as shown in the picture. Change the position of the slide switch from 1 to ON.
2.4.2 Temperature Measurement of Moving Targets To measure moving targets that are not possible to touch, use the following procedure: 1. 2. 3. 4. 5. 6. Press and hold the MEASURE button. The display will briefly show [8888]. Bring the nosepiece as close as possible to the target, preferably within 1/32 inch (1 mm). ** The display may or may not change, but the "beeping" sound will indicate that measurements are being made. Record the temperature from the display. Release the MEASURE button.
5. 6. Record the temperature from the display. Release the MEASURE button. The last reading will remain locked on the display for 10 seconds after releasing the button. 2.6 SCAN Mode Temperature Measurements Use this measurement mode for thermal scanning of a target or when measuring targets located at a distance. The DX is a wide-angle thermal scanner with a fixed emissivity of 0.9.
3.2 Measuring Metallic Targets In general, infrared thermometers can easily measure nonmetallic surfaces because they emit most of their potential heat. Metallic surfaces, on the other hand, are poor emitters and require special treatment before infrared thermometers can accurately measure their temperature. Fortunately, that special treatment is simple and can be easily accomplished by marking the metallic surface you wish to measure with a non-metallic substance such as a solid paint marker.
heat. As long as the ice is not melting, the DX will accurately read its temperature. To make an accurate target measurement, remove any ice or moisture before measuring. Chapter Four - Maintenance The high-performance DX is a rugged and durable instrument, designed for long term performance reliability. 4.1 Battery Replacement Open the instrument's cover to access the battery by loosening the screw on the back of the instrument. Remove the old battery and replace it with one fresh, 9 V alkaline battery.
If the [E-##] or [Err] error messages are displayed, the unit will not function and must be returned to the factory for repair. (See section on Warranty for return instruction). The following charts summarize the fault condition, and the associated indication.
5.2 Troubleshooting Measurement Difficulties If you experience measurement problems, review the following troubleshooting steps: Is the sensor window clean? Clean the sensor window and reflective cup and repeat the measurement. Is the target's surface non-metallic? Coat metallic surfaces with a non-metallic finish and repeat the measurement. Is the target's surface transparent? Coat transparent surfaces with an opaque non-metallic finish and repeat the measurement.
