SAFETY SYMBOLS

Safety symbols and special annunciators on the meter and in this manual 

indicate cautions and warnings of important operational procedures that must 

be followed to ensure personal and product safety.

  This symbol indicates a General Warning. When adjacent to a termi-

nal or operating device indicates that the operator must refer to an 

explanation in the Operating Instructions.

500V

MAX

  This symbol indicates that the terminal(s) so marked must not be con-

nected to a circuit point at which the voltage with respect to ground 

exceeds 500V AC/DC.

 

This symbol adjacent to one or more terminals indicates them as 

being associated with ranges that may in normal use, be subjected 

to particularly hazardous voltages. For maximum safety, the meter 

and its test leads should not be handled when these terminals are 

energized.

 

This meter is protected by double insulation. Service this meter by a 

professional only.
