AC Voltage (ACV)
. Circularly press the “AC/DC” key until
it selects the AC Voltage automatic
measurement mode. Meanwhile, the
symbol “AC”,“AUTO”,“APO” will appear
on the LCD. Respectively plug in the
red and black meter pens into the terminals
of “
VΩ Hz
TEMP ” and “com”. See the picture re below.
2. The initial state of the meter is automatic range,
which shows “AUTO” symbol. Press the “Range” key and switch it to manual range
mode. In the AC mode of automatic/manual range, the frequency/ duty cycle can be
measured by pressing “Hz/DUTY”. However, the frequency response now is low ,
which is suitable for the measurement of high voltage and low frequency in the envi-
ronment of magnetic field interference such as 220V/50Hz-400Hz,380V/50Hz-400Hz.
Caution:
Voltages over DC000V or AC750V cannot be tested. In case “OL” is displayed for
manual range mode, it indicated the range has been exceeded and it is necessary to
select higher range mode to complete this measurement.
