Model UT232: OPERATING MANUAL
The AC Voltage ranges are:15V, 100V, 300V and 600V
The frequency range is:20Hz~500Hz
To measure AC voltage + frequency, connect the Meter
as follows:
1.

4.
Insert the red test lead into the V1 terminal, blue
test lead into the V2 terminal, yellow test lead to
V3 input terminal and black test lead to the COM
input terminal.
Press the MENU to select Voltage (main display)
+ Frequency (secondary display) range.
Connect the red test leads (V1 input terminal), blue
test leads (V2 input terminal) and yellow test leads
(V3 input terminal) to the corresponding three
phases loaded live wire. Black test lead (COM
input terminal) to the corresponding three phases
loaded neutral wire.
Press SELECT to select phase location, the display
shows the corresponding phase symbol. V1 means
the first phase 1, V2 means the first phase 2,
V3 means the first phase 3.

The display shows the corresponding True RMS
voltage value and frequency value of each phase.
Press MAX/ , the LCD displays MAX, it starts
recording the maximum AC voltage True RMS value.
Press MAX/ again to show the current AC voltage
True RMS value.
Press MIN/ the LCD displays MAX, it starts
recording the minimum AC voltage True RMS value.
Press MAX/ again to show the current AC voltage
True RMS value.
The display shows OL when the input voltage is
higher than 600V 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.
