4.5. Diode
1. Connect the black test lead to the COM jack and the red test lead to
the VΩHz jack (NOTE: The polarity of the red lead is positive (+)).
2. Set the range switch to
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 displays will show the approximate forward voltage of the
diode. If the connection is reversed, OL will be shown on the
display.
4.6. Measuring Frequency
1. Connect the black test lead to the COM jack and the red test lead to
the VΩHz jack.
2. Set the range switch to Hz position.
3. Connect the test leads across the source or load to be measured.
4. Read the reading.
NOTE:
The voltage of the input signal should be between 500mV
If the voltage exceeds 20 V
of the specified accuracy range.
4.7. Measuring Insulation Resistance
NOTE:
1. Before you perform insulation resistance test, make sure that the
object to be tested is without power.
2. To avoid electric shock, be cautious. After your finish insulation
resistance test, discharge the tested object fully.
3. To avoid electric shock, do not touch the object under test with your
hand or skin, and do not touch any naked conductor of the meter
(Including test leads) with your hand or skin.
