2.2.6. Diode and Continuity Test
1. Insert the black meter pen to “COM” terminal and the red one to
terminal. (The polarity
of red test lead is “+”)
2. Rotate the Range to “
” gear. Press „SELECT” button to select the Diode
measurement mode.
3. Forward Measurement: Connect the red test lead to the diode positive polarity and the black one
to the diode negative polarity. The approximate value of diode forward voltage drop will show on
the display.
4. Backward Measurement: Connect the red test lead to the diode negative polarity and the black
one to the diode positive polarity. “OL” symbol will be displayed on the screen.
5. The complete diode testing includes forward and backward measurement, if the result does not
meet the above; it means the diode is bad.
6. Press “SELECT” button to select the Continuity measurement mode.
7. Connect the meter pens to two points of the tested circuit. If the built-in buzzer sounds,
the resistance between the two points is less than 50
Ω.

Test Condition
Forward Voltage Drop of
Diode
Forward DC Current is a
pprox. 0.5mA, Backward
Voltage is approx. 1.5V
Buzzer makes a long sound if
resistance is less tan 50
Ω
Open circuit voltage is approx. 0.5V
Overload Protection: 250V DC or AC Peak Value.
CAUTION: DO NOT INPUT VOLTAGE AT THIS RANGE!
2.2.7. Capacity (C)
1. Rotate function switch to “
”
2. Insert the black test lead to “COM” terminal and red one to
terminal.
3. Connect the tested capacity by the test leads to “COM”,
, input terminal, the screen will
show capacitance parameter. (The relative value measurement could be conducted by pressing
“REL” button)
