IMPORTANT SAFETY WARNINGS
WARNING
Read entire safety notes section regarding potential hazard and proper
instructions before using this meter. 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
To ensure safe operation and service of the tester, follow these instructions.
Failure to observe these warnings can result in severe injuries or death.
WARNING
• Before each use, verify meter operation by measuring a known voltage
or current.
• Never use the meter on a circuit with voltages that exceed the category
based rating of this meter.
• Do not use this meter during electrical storms or in wet weather.
• Do not use the meter or test leads if they appear damaged.
• Ensure meter leads are fully seated and keep fingers away from the
metal probe contact when making measurements. Always grip the leads
behind the finger guards molded into the probe.
• Do not open the meter to replace batteries while the probes are connected.
• Use caution when working with voltages above 60V DC or 25V AC RMS.
Such voltages pose shock hazards.
• To avoid false readings that can lead to electrical shock, replace batteries
if a low battery indicator appears.
• Unless measuring voltage or current, shut off and lockout power before
measuring resistance or capacitance.
• Always adhere to national and local safety codes. Use proper personal
protective equipment (PPE) to prevent shock and arc blast injury where
hazardous live conductors are exposed.
• 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 the circuit.
• In the event of electrical shock, ALWAYS bring the victim to the
emergency room for evaluation, regardless of victim’s apparent recovery.
Electrical shock can cause unstable heart rhythms that may need
medical attention.
• If any of the following occurs during testing, turn off the power source to
the circuit being tested: arcing, flame, smoke, extreme heat, smell of
burning materials or discoloration melting of components.
WARNING
Higher voltages and currents require greater awareness of physical safety
hazards. Before connecting the test leads, turn off power to the circuit under
test, set meter to the desired function and range, connect the test leads to
the meter first, then connect to the circuit under test. Reapply power. If an
erroneous reading is observed, disconnect power immediately and recheck
all settings and connections.
WARNING
This meter is designed for trade professionals who are familiar with the
hazards of their trade. Observe all recommended safety procedures that
include proper lock-out utilization and use of personal protective equipment
that includes safety glasses, gloves and flame resistant clothing.

flammable liquids, cleaning solvents, or strong detergents as they may damage the
finish, impair safety, or affect the reliability of the structural components.
STORAGE
Remove the batteries when instrument is not in use for a prolonged period of time.
Do not expose to high temperatures or humidity. After a period of storage in extreme
conditions exceeding the limits mentioned in the General Specifications section, allow
the instrument to return to normal operating conditions before using it.
