IMPORTANT SAFETY WARNINGS (CONT.)

• 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.
