• Read the safety precautions associated with the equipment being
tested and seek assistance or advice when performing
unfamiliar tasks.
• Keep your fingers away from the test lead metal probe contacts
and bus-bars when making measurements. Always grip the
instrument and test-leads behind the hand guards (molded into
the probes).
• In the event of electrical shock, ALWAYS bring the victim to
the emergency room for evaluation, regardless of the victim’s
apparent recovery. Electrical shock can cause an unstable heart
rhythm that may need medical attention.

Safety Notes
Before using this meter, read all safety information carefully. In
this manual the word
"WARNING"
is used to indicate conditions
or actions that may pose physical hazards to the user. The word
"CAUTION"
is used to indicate conditions or actions that may
damage this instrument.
WARNING!
Exceeding the specified limits of this meter is dangerous and can
expose the user to serious or possibly fatal injury.
•
DO NOT
attempt to measure any voltage that exceeds 600 volts
with this meter - UEi offers numerous alternatives for measuring
high voltage and current
• Voltages above 60 volts DC or 30 volts AC may constitute a
serious shock hazard
•
DO NOT
attempt to use this meter if either the meter or the test
leads have been damaged. Send unit in for repair by a qualified
repair facility
• Test leads must be fully inserted prior to taking measurements
• Always turn off power to a circuit (or assembly) under test before
cutting, unsoldering or breaking the current path. Even small
amounts of current can be dangerous
• Always disconnect the live test lead before disconnecting the
common test lead from a circuit
• When measuring high voltage, disconnect the power source before
making test lead connections. Connect the test leads to the meter
first then to the circuit under test. Reapply power
• If any of the following indications occur during testing, turn
off the power source to the circuit under test:
• Arcing
• Flame
• Smoke
• Extreme Heat
• Smell of Burning Materials
• Discoloration or Melting of Components
