English 2 Warning Do not point laser directly at eye or indirectly off reflective surfaces. Cautions Use this unit only as specified in this manual or the protection provided by the unit may be impaired. All models should be protected from the following, v EMF (electro-magnetic fields) from arc welders, induction heaters v Static electricity v Thermal shock (caused by large or abrupt ambi- ent temperature changes-allow 30 minutes for unit to stabilize before use) v Do not leave the unit on or near objects of high temperature Introduction We are confident you will find many uses for your handheld noncontact thermometer. Compact, rugged, and easy to use-just aim, press the trigger, and read surface temperatures in less than a second. You can 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 (E), reflected (R), and transmitted (T) energy, which is collected and focused onto a detector. The unit's electronics translate the information into a temperature reading which is displayed on the unit. The laser is used for aiming purposes only.
