AC VOLTAGE (FREQUENCY, DUTY CYCLE) MEASUREMENTS
WARNING:
Risk of Electrocution. The probe tips may not be long enough to contact
the live parts inside some 240 V outlets for appliances because the contacts are
recessed deep in the outlets.
As a result, the reading may show 0 V when the outlet actually has voltage on it.
Make sure the probe tips are touching the metal contacts inside the outlet before
assuming that no voltage is present.
CAUTION:
Do not measure AC voltages if a motor on the circuit is being switched
ON or OFF. Large voltage surges may occur that can damage the meter.
1. Set the function switch to the green
VAC/Hz/%
position.
2. Insert the black test lead banana plug into the
negative
COM
jack.
Insert red test lead banana plug into the positive
V
jack.
3. Touch the black test probe tip to the neutral side
of the circuit.
Touch the red test probe tip to the “hot” side of
the circuit.
4. Read the voltage on the main display and the
frequency in the right auxiliary display
5. Press and hold the
MODE
button for 2 second to
indicate “
Hz
”.
6. Read the frequency on the main display.
7. Press the
MODE
button to indicate “%”.
8. Read the % of duty cycle on the main display.
9. Press
EXIT
for 2 seconds to show the function
of AC+DC. Test DC and AC TURE rms.
MV VOLTAGE MEASUREMENTS
CAUTION:
Do not measure mV voltages if a motor on the circuit is being switched
ON or OFF. Large voltage surges may occur that can damage the meter.
1. Set the function switch to the green
mV
position.
2. Press the
MODE
button to indicate “
DC
”.or “AC ”.
In AC range press
EXIT
for two seconds and
chose ”AC+DC”
3. Insert the black test lead banana plug into the
negative
COM
jack.
Insert the red test lead banana plug into the
positive
V
jack.
4. Touch the black test probe tip to the negative side
of the circuit.
Touch the red test probe tip to the positive side of
the circuit.
5. Read the mV voltage on the display.
