AC/DC Voltage Measurement
Measure AC conductors carrying
up to 600 VAC, 50-60 Hz.
Measure DC conductors
carrying up to 600 VDC.
WARNING!
Use caution when working
near voltages above 30 VAC rms, 42
VAC peak, or 60 VDC. Voltages this
high present a risk of electric shock.
1. Plug black Test Lead into
black
COM
Jack.
Plug red Test Lead into red Input Jack.
2. Turn Rotary Switch to
v
position.
3. Press
SELECT
button to choose
between
AC
and
DC
.
4. Carefully touch exposed
conductors with tips of probes.
5. Read measurement.
6. To compare difference between
two readings, press
REL
button
to store current reading. Take
second measurement, reading
will be difference between
first and second reading.
Note:
If voltage is too high,
display will read
OL.
7. When testing is complete, turn
Rotary Switch to
OFF
, remove
Test Leads and store with Meter.
Diode Measurement
Test voltage drop in diodes. Open
circuit voltage is 1.5V.
WARNING!
To prevent electric
shock, disconnect all power to
circuit and discharge all high-voltage
capacitors before measuring.
1. Plug black Test Lead into
black
COM
Jack.
Plug red Test Lead into red Input Jack.
2. Turn Rotary Switch to
Ω
position.
3. Press
SELECT
Button
until is displayed.
4. Connect red probe to diode’s anode
and black probe to its cathode.
5. Approximate forward voltage drop
of diode will be displayed in mV.
Note:
If circuit is open or diode polarity
is reversed, display will read
OL.
6. When testing is complete, turn
Rotary Switch to
OFF
, remove
Test Leads and store with Meter.
