Safety & Warnings
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. Do not keep or use this unit in an environment where it will be directly illuminated by sunshine, or where it will be exposed to high temperatures, high humidity or condensation. If you do, it may be deformed, its insulation may be damaged, or it may no longer function according to specification. Do not point the lens at the sun or at any other source of strong light. If you do, the sensor may be damaged. Do not contact the lens against the object whose temperature is to be measured, or get it dirty, allow it to be scratched, or allow any foreign material to adhere to it. Doing so may cause errors. Do not touch or hold by the front cone. Temperature reading can be affected by heat from hand. Do not place the meter on or around hot objects (70°C/158°F). It may cause damage to the case. If the meter is exposed to significant changes in ambient temperature (hot to cold or cold to hot), allow 20 minutes for temperature stabilization before taking measurement. Condensation may form on the lens when going from a cold to hot environment – wait 10 minutes for condensation to dissipate before taking measurements. Do not allow the laser light beam to enter your eye or those of any other person or animal. Do not look directly into the laser light from the optical system. When measuring the temperature of an object which has a mirror finish, be careful not to allow the laser light beam to be reflected off the surface into your eyes or those of another person. Do not allow the laser light beam to impinge upon any gas which can explode. This unit is not constructed to be waterproof or dustproof, so do not use it in a very dusty environment or in one where it will get wet.
