1. Product Introduction Thank you for purchasing this infrared thermometer. The Infrared Thermometer is a non-contact infrared temperature measuring instrument. To measure a temperature , point the unit at the object until the temperature is read , pull the measuring trigger and hold. Make sure the target area is larger than the unit's spot size. For large target objects assure you are within target distance. 1-1 Features Features with board temperature and high DS ratio.
2. Safety Information Read the following safety information carefully before attempting to operate or service the meter. Only qualified personnel should perform repairs or servicing not covered in this manual. Laser Warning Note! D o no t point laser directly at eye . Use caution a round reflective surfaces. Keep out of reach of children. 2-1 Cautions! DO NOT submerge the unit in water. This product is not designed for use in medical evaluations.
2-2 Safety symbols Dangerous, refer to this manual before using the meter. CE Certification.

4.3 Operation Functions To operate more advance functions, it is simply by using MODE button to change. The sequential operations and the corresponding explanations are shown in the following flow-chart. Operation Mode SCAN ●Scan and display the temperature during measurement. MAX ●The maximum temperature within one shot measuring.. MIN ●The minimum temperature within one shot measuring. AVG ●The average temperature within one shot measuring.
Remarks a. Memory: Activate the record function by push the M button. To delete all the records, press up or down button to DATA0 and press “M” button. b. LOCK: Push the button to continuously measure and display the temperature without pull the measuring trigger. c. The above functions can be activated always in any step of operations mode in flow-chart. d. In SCAN mode, the LCD displays both the current temperature in Celsius or Fahrenheit.
4.4 °C/°F, Laser Switch and Battery Change The unit is powered by 9V battery and displays temperatures in either ° C or ° F. The user has to replace the battery when the battery voltage drops below the voltage for reliable operation and at the same time the low battery symbol will appear. To change the 9V battery, pull open the unit's handle under the trigger. After replacing the battery push back and snap in place.
5. Techniques of Infrared Thermometer 5.1 Field of View (FOV) ratio = Distance to Diameter (DS) ratio The field of view is the angle of vision at which the instrument operates , and is determined by the optics of the unit. The FOV is the ratio of the distance from the target to the target diameter. The smaller the target , the closer you should be to it .
5.2 Emissivity Emissivity is the ability of an object to emit or absorb energy. Perfect emitters have an emi ssivi ty of 1 , emitting 100% of incident energy. An object with an emissivity of 0.8 will absorb 80% and reflect 20% of the incident energy. Emissivity is def ined as t he r atio of the energy radiated by an object at given temperature to the energy emitted by a perfect radiator at the same temperature. All values of emissivity fall between 0.0 and 1.0.
