CAUTION

• Do not use the unit near any device which generates strong electromag-

netic radiation or near a static electrical charge, as these may cause errors.

• 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 conden sation to dissipate befor taking
measurements.

• This unit is not constructed to be water proof or dustproof, so do not use it

in a very dusty environment or in one where it will get wet.
