AC Voltage Measurement
（
see Figure 4
）
To measure AC voltage, connect the Meter as follows:
·
Set the rotary switch to
position
.
·
Connect the RED test lead into “V
Ω
” input terminal and
BLACK test lead into “COM” input terminal.
·
Connect the test leads across with the object being
measured.
·
Read the value from display. AC voltage reading is effective
value of sine wave (mean value response).
Warning
a) To avoid harms to you or damages to the Meter from
eletric shock, do not attempt to measure voltages higher
than DC 1000V or AC 750Vrms, although readings may be
obtained.
b) When the Meter working at an effective voltage over
60V in DC or 30V rms in AC, special care should be taken
for there is danger of electric shock.
c) 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.
