The AC Voltage ranges are: 100 V, 400 V and 750 V.
The frequency range is: 50 Hz~ 60 Hz.
To measure AC voltage + frequency, connect the Meter as
follows:
1. Insert the red test lead into the
L1, L2, L3
input
terminal, and
black test lead to the
COM
input terminal.
2. Dial the Rotary to VAC to select V Frequency range.
3. Connect the red test leads (
L1, L2, L3
input terminal)to the
corresponding three phases loaded live wire. Black test lead
(COM input terminal) to the corresponding three phases
loaded neutral wire.
4. Press
SEL
to select phase location, the display shows the
corresponding phase symbol.
L1
means the first phase
,
L2
means the second phase
,
L3
means the third phase
.
5. The display shows the corresponding True RMS voltage
value and frequency value of each phase.
6. Press
MAXMIN
, the LCD displays
, it starts recording
the maximum AC voltage True RMS value.
7. Press
MAXMIN
the LCD displays
, it starts recording the
minimum AC voltage True RMS value. Press
MAXMIN
again
to show the current AC voltage True RMS value.
8. The display shows
0L
when the input voltage is higher than
750V rms.
Note
When the measurement has been completed, disconnect the
connection between the testing leads and the circuit under test
and remove testing leads from the input terminals.
