CAUTION

 

 
 
 

Warning of laser 

Do not point laser beam to human eyes directly or indirectly from 
reflective surfaces. 
 

Cautions 

Before using the infrared thermometer the operator have to notice 
the following: 

 

Keep away from electrical welders, induction heaters and other 
EMF sources. 

 

When using this thermometer under big or abrupt ambient 
temperature changes, allow 15 minutes for the unit to stabilize 
before use. 

 

Do not keep this thermometer in the environment of high 
temperature for a long period. 

 

Keep away from dusty environment and keep it in the carry 
case after operation to avoid contamination of optical lenses.
