Page 3: Safety Information
This instrument is a portable easy to use 3 digit, compact-sized digital infrared thermometer with laser sighting designed for simple one hand operation. Meter comes with Backlit LCD display, Auto-hold function and auto power down (20 seconds approx.) after releasing MEAS button to extend battery life. - Page 4 • 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.

Page 8: Turning The Power On
OPERATING INSTRUCTIONS Auto Power-down function If unused for about 20 seconds, the unit will power-down automatically. Press MEAS button resumes power-on mode. SET MODE disables auto power-down feature. Turning the Power on When the power is down, press MEAS button to turn on the meter. The values and settings on the LCD return to what they were before the power was last turned off. -
Page 9: Laser Sighting
Selecting the Temperature Scale Readings are displayed in either degrees Celsius(°C) or degrees Fahrenheit(°F). When the thermometer is turned on, it is set to the temperature scale that was in use when the thermometer was last turned off. To change the temperature scale, in power down mode hold the "... -
Page 10: Continuous Measurement
Continuous Measurement 1. In the power down mode, holding the MODE key down and then pressing the MEAS key will put the unit into the continuous measurement mode. 2. When the MEAS key is pressed again to stop measuring temperature and automatically hold the display reading, the meter power down automatically after 20 seconds. -
Page 11: Mode Selection And Operation
MODE SELECTION AND OPERATION Press MODE button switches the mode around the cycle e ® ALM Hi ® ALM Lo ® MAX ® MIN ® HOLD. HOLD :Releasing MEAS button stops measuring temperature, the HOLD indication appears, and the measured temperature is held. :The thermal emissivity of the object set using the ALM Hi :The upper limit alarm temperature is set using the When the measured temperature is exceeded the Hi setpoint, the... - Page 12 NOTE: If, from the power down condition, the MEAS key is held down for more than four second, MAX/MIN record starts. SET MODE & Numeric input key "SET" annunciator appears when a numerical value can be set (during setting of e, ALM Hi and ALM Lo).
- Page 13 How to specify the thermal emissivity ( e e e e e ) 1. Stick black body tape on the object whose temperature is to be measured, or spray it with black body spray. 2. Set the thermal emissivity value (e) on the LCD to 0.95. 3.

Page 15: Measurement Considerations
Infrared radiation is a form of light (electromagnetic radiation), and has the property that it passes easily through air while it is easily absorbed by solid matter. With an emission thermometer which operates by detecting infrared radiation accurate measurement is possible, irrespective of the air tempera- ture or the measurement distance. - Page 16 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.
