Diode test
1) Set the range switch to
2) Press the "SELECT. " key to select
continuity measurement mode. The
symbol " " will appear as an indicator.
3) Connect the red test lead to the anode of
the diode to be tested and the black test
lead to the cathode.
4) The meter will show the approximate
forward voltage of the diode. If the
connections are reversed, "OL" will be
shown on the display.
Capacitance measuring
1) Set the range switch to
2) The meter defaults to the nF capacitance
test range.
3) Connect test leads across the capacitor
to be measured. Pay attention to the
polarity of the connection.
Note:
• All capacitors must discharge fully before
testing. Discharge the capacitors before
measuring, i.e. switch off all power
sources that are powered on, then start
to measure the capacitors for those
power sources (which are now powered
off ).
• If the measured capacitance is a polar
capacitance. When measuring, the red
meter pen should be connected to the
positive pole of the capacitance, and the
black meter lead should be connected
to the capacitance. The negative pole of
It takes a few seconds to display the test
value for capacitors larger than 10μF,
which is a normal phenomenon.
• Do not enter a voltage higher than 60 V
DC or AC 30Vrms to avoid damaging the
meter and harming yourself.
Frequency and duty measuring
range. 1) Set the range switch to "Hz%" range
2) Press the Hz% key to select the
3) The meter defaults to the frequency test
NOTE: The input voltage should be between
200mV and 10V rms AC. If the voltage is more
than 10V rms, the reading may be outside
the accuracy range.
Auto Power Off
If you don't operate the meter for about 30
minutes, it will turn off automatically.

Press the "SELECT" key to wake up the meter
when it is in dormant state. The auto power
off function is cancelled.
The meter do not deactivate the function of
auto power off .

Battery replacement

If the sign "
it indicates the battery needs replacing.
Remove the screws and open the back of the
case. Replace the exhausted battery with a
new one (CR2032, size: 20x3.2 mm).
Open case
The meter has a box design. Press the left
button to open the front cover. Once you
