EMF Exposure 

The effect of EMF exposure is a modern day concern. At the time of this writing, to the best of our 

knowledge, no standards or recommendations exist regarding limits of EMF exposure. Exposure 

limits of 1 to 3mG have been suggested by several international bodies. Until evidence suggests 

that there is not a health risk associated with EMF exposure, common sense would dictate that a 

practice of minimal exposure be exercised.  
 
 

Battery Replacement 

When the low battery icon appears on the left corner of the LCD, the 9V battery has fallen to a 

critically low voltage level and should be replaced as soon as possible. The battery compartment 

cover is located at the bottom rear of the meter. Remove the Phillips head screw that secures the 

battery compartment and slide off the battery compartment cover. Replace the battery and secure 

the compartment cover before use.
