Operation
Low Z AC/DC Voltage
WARNING:
Observe all safety precautions when working on live
voltages. Do not connect to circuits that exceed 300V when the meter is set
to Low Z. Do not use Low Z when testing circuits that could be harmed by
this function's low input impedance.
Low Z is used to check for "ghost" voltage. Ghost voltages are present when
non-powered wires are in close proximity to powered wires. Capacitive coupling
makes 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 greatly reduces
the voltage reading when connected to a ghost voltage.
1. Set the rotary function switch to
the Low Z position.
2. Press the MODE button to select
~
AC or DC voltage. The AC "
" or
DC " " symbol will appear on
the LCD display.
3. Insert the black test lead into
the COM input jack and the red
test lead into the V input jack.
4. Touch the test leads to the circuit
under test. If measuring DC
voltage, touch the red test lead to
the positive side of the circuit and
the black test lead to the negative
side of the circuit.
5. Read the voltage on the LCD display.

AC Current Measurements
WARNING:
working on live circuits. Do not measure current on circuits
that exceed 600V. Measurements in the 10A range should
be limited to 30 seconds maximum every 15 minutes.
1. Set the rotary function switch
to the
position.
2. Insert the black test lead into the
COM input jack and the red test
lead into the 10A input jack.
3. Remove power from the circuit
under test, then open up the
circuit at the point where you wish
40
to measure current.
4. Touch the test lead probes in series with
the circuit being measured.
5. Apply power to the circuit.
6. Read the current on the LCD display.
