AC Voltage Measurement

(Figure 2)
Warning
To avoid harms to you or damages to
the Meter from electric shock, please do
not attempt to measure voltages higher
than 500Vrms although readings may
be obtained.
The AC voltage measurement positions are: 200V
and 500V. To measure AC Voltage, connect the
Meter as follows:
1. Insert the red test lead into the VΩmA terminal
and the black test lead into the COM terminal.
2. Set the rotary switch to an appropriate
measurement position in V
3. Connect the test leads across with the object
being measured. The measured value shows on
the display, which is effective value of sine wave
(mean value response).
range.
Note:
• If the value of voltage to be measured is
unknown, use the maximum measurement
position (500V) and reduce the range step by
step until a satisfactory reading is obtained.
• The LCD displays "1" indicating the existing
selected range is overload, it is required to
select a higher range in order to obtain a correct
reading.
• In each range, the Meter has an input impedance
of approx. 10MΩ. This loading effect can cause
measurement errors in high impedance circuits.
If the circuit impedance is less than or equal to
10kΩ, the error is negligible (0.1% or less).
• When AC voltage measurement has been
completed, disconnect the connection between
the testing leads and the circuit under test.
