Special Panel Markings
MEASURE CURRENT AND
VOLTAGE IN COMMERCIAL
ELECTRICAL PANELS. UNLIKE
A HOME AC OUTLET, A COM-
MERCIAL ELECTRICAL PANEL
HAS TREMENDOUS CUR-
RENT SURGE POTENTIAL.
THIS IS ESPECIALLY TRUE
FOR THREE-PHASE INDUS-
TRIAL ELECTRICAL PANELS. A
SMALL SPARK FROM ONE OF
THESE PANELS CAN CAUSE A
PLASMA EXPLOSION AND
FIRE THAT CAN SEVERELY
BURN YOU. DO NOT HOLD
THE MULTIMETER WHILE
USING IT.
• ALWAYS WEAR PROTECTIVE
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.
• IF THIS EQUIPMENT IS USED
IN A MANNER NOT SPECIFIED
BY THE MANUFACTURER,
THE PROTECTION PROVIDED
BY THE EQUIPMENT MAY BE
IMPAIRED.
• TO REDUCE THE RISK OF
FIRE OR SHOCK HAZARD, DO
NOT EXPOSE THIS PRODUCT
TO RAIN OR MOISTURE.
