Page 3: How The Thermometer Works
HOW THE THERMOMETER WORKS The infrared thermometer consists of optical system, photo detector, signal amplifier, signal processing and display output system, and etc. The optical system collects the infrared radiation energy of the measured area, then this energy is focused onto the photo detector and changed into electric signal, which is further converted into temperature value shown on the display. -

6. Do not point the laser beam toward anyone's eye or allow the laser beam to strike the eye from a reflective surface. WAVELENGTH 630nm - 670nm Cautions The thermometer should be protected from the following: 1. Electro magnetic fields ( created by arc welders, induction heaters and similar items. - Page 5 the following figure. At a distance of 12 inches, the spot size would be 1 inch in diameter. The thermometer will display the average temperature across the spot area. Distance Spot Center 1" @ 12" 2" @ 24" 3" @ 36" Distance to Spot size = 12 : 1 Note: Make sure that the object to be measured is larger than the...

on the bottom display; for example, if the symbol " MAX " appears, it means that the value on the bottom display is maximum value. 8. Bottom display used to display maximum (MAX), minimum (MIN), difference (DIF), average (AVG), high alarm value (HAL) and low alarm value (LAL). - Page 10 1. " " Button 1. Used to change temperature value(s) from celsius value(s) to fahrenheit value(s). 2. When setting emissivity ( ), high alarm value ( HAL ), or low alarm value ( LAL ), press this " " button to increase the value to be set.
- Page 11 release the trigger, the last reading is locked until you make new measurement or the thermometer turns off automatically. You can press the MODE button to display the maximum (MAX), average (AVG), minimum (MIN), difference (DIF), low alarm value (LAL) and high alarm value (HAL) sequentially on the bottom display.
- Page 12 BASIC MEASUREMENT PORUCEDURE 1. Hold the thermometer by its handle, and point it toward the surface to be measured. 2. Pull and hold the trigger for at least 1 sec to turn on the thermometer and make measurement, reading will be displayed on the main display.

Page 13: Measurement Considerations
Target Area While holding trigger down Measurement Considerations: 1. Laser beam is mainly used to locate far object. To save battery power, you can disable the laser function when you measure near object. 2. The thermometer can not measure through transparent surfaces such as glass. - Page 14 the present low alarm value is being shown on the bottom display. 3. Press the " " button to decrease or the " " button to increase the low alarm value. Tip: You can press and hold down the " "...
- Page 15 oxidized surfaces have an emissivity of 0.95 ( preset in the thermometer ). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cover the surface to be measured with masking tape or flat black paint. Allow time for the tape or paint to reach the same temperature as the surface beneath it.

The thermometers allow you to adjust the thermometer's emissivity setting value so as to match the type of surface to be measured. How to Set Emissivity 1. When the thermometer is on, press and hold down the " MODE " button until the symbol "... -
Page 17: Battery Replacement
BATTERY REPLACEMENT When the symbol " " appears, the battery is low and should be replaced immediately. Wait until the thermometer turns off automatically, then open the battery cover gently with thumb at the location indicated in the following figure. Replace the exhausted battery with a new one of the same type. - Page 18 DISPOSAL OF THIS ARTICLE Dear Customer, If you at some point intend to dispose of this article, then please keep in mind that many of its components consist of valuable materials, which can be recycled.
