1 INTRODUCTION 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.
2 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.
3 SPECIFICATIONS GENERAL Display: 3½ digit liquid crystal display (LCD) with maximum reading of 1999. Low battery indication: the " " is displayed when the battery voltage drops below the operating level. Measurement rate: 1 times per second, nominal.
4 Laser Specifications Laser safety classification of Class II Wave Lenght: Red (650nm). Operating Distance: 2 to 50 feet. Power out: <1mW , class II laser product. ELECTRICAL Temperature Range: -4°F to 1022°F / -20°C to 550°C. Display Resolution: 1°F / 1°C.
5 Spot size increases with distance from the probe tip as shown (Spot Diameter measured at 90 % Energy) CAUTION: Use of controls or Adjustments or performance of Procedures other than those Specified herein may result in Hazardous radiation exposure.
6 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.
7 Laser Sighting Press " " button to on the " " annunciator. If " " annunciator is on, press MEAS button and the laser beam will turn on and " " annunciator will blink. Releasing MEAS button turns off the laser beam.
8 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.
9 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.
10 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).
11 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.
12 OPERATION 1. When the power is down, pressing MEAS button turns on the power. 2. Use " " button to select turn on or turn off the display Back-Light. 3. Use " " button to select turn on or turn off the Laser beam. 4. Press the MODE button, if necessary to set the thermal emissivity value ( e ).
13 MEASUREMENT CONSIDERATIONS 1. Theory of Measurement Every object emits infrared energy in accordance with its temperature. By measuring the amount of this radiant energy, it is possible to determine the temperature of the emitting object.
14 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.
15 MAINTENANCE Battery Replacement Power is supplied by four 1.5V (AAA size) batteries. The " " appears on the LCD display when replacement is needed. To replace the batteries, remove the screw from the back of the meter and lift off the battery cover case.
