Testing Diodes

To avoid electrical shock and damage the meter when measuring diode in a
circuit, make sure the power to the circuit is turned off and all capacitors are
discharged.
1. Turn the rotary switch to
from the circuit to be measured.
2. Press the yellow button twice.
3. Connect the red test probe to the anode side and black test lead to the
cathode side of the diode being tested.
4. Read the forward bias voltage value on the display.
5. If the polarity of the test leads is reversed with diode polarity or forward bias
voltage is above 3V, the display reading shows OL.
This can be used to distinguish the anode and cathode sides of the diode.

Measuring Capacitance

To avoid electrical shock and damage to the meter when measuring capacitance
in a circuit, make sure the power to the circuit is turned off and all capacitors are
discharged.
Only Autorange is available in this mode.
1. Turn the rotary switch to
from the circuit to be measured.
2. Connect the red test lead to the + terminal and the black test lead to the COM
terminal.
3. Press the yellow button three times.
4. Touch the probes to the capacitor leads.
5. After allowing reading to stabilize, read the capacitance value on the display.
In the capacitance range 100mF the measure can be long and exceed 15s.
