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. The values and settings on the LCD return to what they were[...]

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. MEAS (MEASURE) Button Press MEAS button to turn on the meter for measuring temperature. Relea[...]

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. NOTE: During the con[...]

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. e :The thermal emissivity of the object set using the ▲ and ▼ keys. ALM Hi :The upper limit a[...]

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). ▲ key :The numerical value is increased. ▼ key :The numerical value is reduced. [...]

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. 2. Set the thermal emissivity value ( e ) on the LCD to 0.95. 3. Press the MEAS key, so as to measure the temperature (T real ) of the part on which body tape (or black body spray) is [...]

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 ). 5. Point the lens at the object[...]

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. 2. About Infrared Infrared radiation is a form of light (electromagnetic radiation), and has the property th[...]

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. Emissivity values range from 0.10 for a very reflective object to[...]

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. Remove the batteries from battery contacts. Cleaning Periodically wipe the case wi[...]
