1) To reduce the risk of fire or electric 
shock, do not expose this product to rain or 
moisture. The meter is intended only for 
indoor use. 
To avoid electrical shock hazard, observe 
the proper safety precautions when 
working with voltages above 60 VDC or 30 
VAC rms. These voltage levels pose a 
potential shock hazard to the user.  
Keep your hands/fingers behind the 
hand/finger barriers (of the meter and the 
test leads) that indicate the limits of safe 
access of the hand-held part during 
measurement. Inspect test leads,

insulation or exposed metal before using 
the instrument. If any defects are found, 
replace them immediately. 
This Clamp-on meter is designed to apply

individual protective equipment must be 
used if hazardous live parts in the 
installation where measurement is to be 
carried out could be accessible.
