AC Voltage Measurement
(Figure 4)
To avoid harms to you or damages to the Meter
from electric shock, please do not attempt to
measure voltages higher than 600 V / 600 V rms
although readings may be obtained.
The AC voltage ranges are: 4 V, 40 V, 400 V and 600 V.
To measure AC Voltage, connect the Meter as follows:
1. Insert the red test lead
into the V terminal and
the black test lead into
the COM terminal.
2. Set the rotary switch
to V ; AC measurement
is default or press BLUE
button
to
measurement mode.
3. Connect the test leads
across with the object
being
measured.
measured value shows on
the display.
Note:
• In each range, the
Meter has an input
impedance of 10M. This
loading effect can cause measurement errors in high
impedance circuits. If the circuit impedance is less than
or equal to 10 k, 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, and remove the testing leads
away from the input terminals of the Meter.
• Root mean square value stability period: When the
reading obtained is less than 100 digits, the root mean
square value converter needs a longer time to stabilize.
When there is no input voltage, the maximum reading
displayed is 10 digits.
