1.2 Caution
Infrared thermometer should be protected for the following:
-
EMF (electro-magnetic fields) from arc welders and induction heaters.
-
Thermal shock (caused by large or abrupt ambient temperature changes allow 30 minutes for unit to stabilize
before use).
-
Do not leave the unit on or near objects of high temperature.
Warning: Do not point laser directly at eye or indirectly off reflective surfaces!
