Special Panel Markings
MEASURE CURRENT AND
VOLTAGE IN COMMERCIAL
ELECTRICAL PANELS. UNLIKE

BURN YOU. DO NOT HOLD
THE MULTIMETER WHILE
USING IT.

LEATHER GLOVES, A FACE
SHIELD, AND FIREPROOF ARM
AND UPPER BODY PROTEC-
TION WHILE USING THE MULTI-
METER TO MEASURE
CURRENT AND VOLTAGE IN
COMMERCIAL ELECTRICAL
PANELS.
