INTRODUCTION This instrument is a portable easy use compact-sized digital infrared temperature transducer with laser marker designed for simple one hand operation. SAFETY INFORMATION It is recommended that you read the safety and operation instructions before using the infrared thermometer. The symbol on the instrument indicates that the operator must refer to an explanation in this manual. DANGER Pressing the button turns the laser marker on and off.
CAUTION • Do not use the unit near any device which generates strong electromagnetic radiation or near a static electrical charge, as these may cause errors. • Do not use the unit where it may be exposed to corrosive or explosive gases. The unit may be damaged, or explosion may occur. • Do not keep or use this unit in an environment where it will be directly illuminated by sunshine, or where it will be exposed to high temperatures, high humidity or condensation.

OPERATING INSTRUCTIONS Push buttons Laser Marker Button Release MEAS button then press " " button to toggle between turn on and turn off the Laser Marker annunciator, If " " annunciator turn on, press MEAS button the laser marker beam is being emitted, releasing MEAS button turn off the laser marker beam. MEAS (MEASURE) Button Depress MEAS button to turn on the meter for temperature measurement. Release the MEAS button to stop temperature measurement.
OPERATION 1. Plug the infrared temperature transducer test leads into the Vdc input jack and common or ground input jack on the DMM. Observe polarity. 2. Set the DMM to the 2V range only, ignore the decimal point. 3. Use " " button to select turn on or turn off the Laser Marker. 4. Point the lens at the object whose temperature is to be measured. 5. Press the MEAS button. Measurement is performed as long as the MEAS button is kept pressed. 6.
MEASUREMENT CONSIDERATIONS 1. Theory of Measurement Every object emits infrared energy in accordance with its temperature. By mesuring the amount of this radiant energy, it is possible to determine the temperature of the emitting object. 2. About Infrared Infrared radiation is a form of light (electromagnectic radiation), and has the property that it, passes easily through air while it is easily absorbed by solid matter.
4. Emissivity All objects emit invisible infrared energy. The amount of energy emitted is proportional to the object's temperature and its ability to emit IR energy. This ability, called emissivity, is based upon the material that the object is made of and its surface finish. Emissivity values range from 0.10 for a very reflective object to 1.00 for a black body. Factory set emissivity value of 0.95, which cover 90% of typical applications. 5.
MAINTENANCE Battery Replacement Power is supplied by four 1.5V (AAA size) batteries. The "LOW BATT" red LED lighted when replacement is needed.To replace the batteries, remove the screw from the back of the meter and lift off the battery cover case. Remove the batteries from battery contacts. Cleaning Periodically wipe the case with a damp cloth and detergent, do not use abrasives or solvents.
