Low Z voltage
Notes:
Observe all safety precautions when working on live
voltages. Do not connect to circuits that exceed 600
VAC/DC when the meter is set to Low Z.
Low Z is used when there is a suspicion of a 'ghost' voltage. Ghost
voltages are present when non-powered wires are in close proximity
to wires powered by AC voltage. Capacitive coupling between wires
make it appear that non-powered wires are connected to a real source
of voltage.
The Low Z setting places a load on the circuit, which dissipates and
greatly reduces ghost voltage.
Set the function switch to the 'V ~ LowZ' position.
