AC Voltage Measurement
(See Figure 2)
AC Voltage Ranges:
200V, 500V
Input Impedance:
5M
Ω
1. Plug the red test lead into the V
Ω
mA terminal, then
plug the black test lead into the COM terminal.
2. Set the rotary switch to the appropriate
measurement in V~ range.
3. Connect the test leads to the object of measurement.
Hold them in place until the results on the display
stabilize. The displayed measured value is the value
of sine wave (mean value response).
4. When measurement is completed, disconnect the test
leads from the object of measurement.
NOTE
•
If the value of voltage is unknown, use the maximum
measurement position (500V) and reduce the range
until proper readings are obtained.
•
The LCD will display “OL” if there in an overload
within the selected range. Select a higher range to
obtain a correct reading.
•
If the circuit impedance is less than or equal to 10k
Ω
,
the error is negligible (0.1% or less).
