Handling the Instrument
• To avoid short circuits and potentially life-threatening
hazards, never attach the clamp to a circuit that operates
at more than 600 V AC, or over bare conductors.
• The maximum rated voltage between input terminals and
ground is 600 V AC. Measuring a voltage in excess of this
rating relative to ground could damage the instrument
and result in bodily injury.
• To avoid electric shock, do not remove the instrument's
case. The internal components of the instrument carry
high voltages and may become very hot during operation.
• When the clamp sensor is opened, do not allow the metal
part of the clamp sensor to touch any exposed metal, or
to short between two lines, and do not use over bare con-
ductors.
To avoid electric shock when measuring live lines, wear
appropriate protective gear, such as insulated rubber
gloves, boots and a safety helmet.
