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.
SPECIFICATIONS GENERAL Low battery indication: the "Red LED " is displayed when the battery voltage drops below the operating level. Operating Environment: 0°C to 50°C at < 70% relative humidity. Storage Temperature: -20°C to 60°C, 0 to 80% R.
4 ELECTRICAL Temperature Range: -20°C to 260°C. Analog Output: 1mV/°C. Accuracy: ±3% of reading or ±3°C, whichever is greater @ 18 to 28°C ambient operating temperature. Temperature Coefficent: ±0.2% of reading or ±0.2°C, whichever is greater, change in accuracy per °C change in ambient operating temperature above 28°C or below 18°C.
5 Spot size increases with distance from the probe tip as shown CAUTION: Use of controls or Adjustments or performance of Procedures other than those Specified herein may result in Hazardous radiation exposure.
6 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.

8 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.
9 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.
10 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.
