Measurement Operation (3)
B. AC Voltage Measurement (see 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 V
Ω
mA terminal and the black test lead into the
COM terminal.
2. Set the rotary switch to an appropriate measurement position in V range.
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).
