Introduction Compact,rugged and easy to use.Just aim and pull the button, read current surface temperature in less that a second.Safely measure surface temperatures of hot,hazardous or hard-to-reach objects without contact. How it works Infrared thermometers measure the surface temperature of an object. The unit's optics sense emitted,reflected and transmitted energy which is collected and focused onto a detector.The unit's electronics read transmitted energy and display temperature on the screen. For increased ease and accuracy the laser pointer makes aiming even more precise. Measuring repetitiveness:≤±0.2°C Measuring precision:Lab:±0.2°C,within measuring range 35.0°C-42.0°C and under environment temperature 10-40°C. Measuring Range: Body temperature: 32°C-42°C(89.6°F - 107.6°F) Surface temperature: 5.0°C - 80.0°C(41.0°F - 176.0°F) Relative humidity: ≤85% Power: DC3V(AAA*2) Measure time: 1 second Quick start instruction 1. open battery door,install battery correctly. Press the button, LCD display reading ＆ battery icon.Release the button and the reading will hold for 7 seconds. Cautions Infrared thermometer should be protected for the following: -- EMF (electro-magnetic fields) from arc welders,induction heaters. -- Thermal shock(caused by large or abrupt ambient temperature changes,allow 1 hours for unit to stabilize before use). -- Do not leave the unit on or near high temperature objects. -- Do not hold the button for long time, or it will be calibration mode. Warning Do not point laser at eye either directly or indirectly off reflective surfaces. 1.When taking measurement,point thermometer toward the object to be measured and hold the yellow trigger. The object being tested should be larger than the spot size calculated by the field of view diagram. 2.Distant ＆spot size:As the distant from the
