The probe consists of precision components such as Magnetic core and Hall sensor, which could be 

possibly damaged because of the sudden temperature change or external force impact. Please be 

careful for vibration or impact. 

 

The product is neither waterproof nor dustproof; please do not operate in the environment filled 

with dust and water.   

 

The probe’s upper and lower contact surfaces is made by precise polishing process. Please protect 

this part or the probe could be malfunction.   

 
 
 
 

 

When the battery voltage is lower than 6.5V, the probe will indicate a low voltage alert, please 

change the battery. You can use a 9V alkaline battery for longer time.
