To avoid possible damage to the meter or to the equipment under test:
Set the rotary switch on the right range. Do cut off the testing leads and circuit before switching. Forbid to switch
during the measuring process.
Cut off the power and complete discharge before measuring resistance, continuity, diodes, or capacitance with the live
circuit.
Before measuring current, check the meter's fuses (see Chapter 6 "Testing the Fuses"). Turn power OFF to the circuit
before connecting the meter to the circuit. Remember: Plug the meter with the circuit when measuring current and do
not connect test lead in parallel with any circuit.
