3. Insert the black test lead banana plug into the negative COM
jack and the red test lead banana plug into the positive Ω jack.
4. Touch the test probe tips to the diode or semiconductor junction
you wish to test. Note the meter reading.
5. Reverse the probe polarity by switching probe position. Note
this reading.
6. The diode or junction can be evaluated as follows:
A: If one reading shows a value and the other reading show
OL, the diode is good.
B: If both readings are OL, the device is open.
C: If both readings are very small or 0, the device is shorted.
Note: The value indicated in the display during the diode check is
the forward voltage.
5.10. Frequency / Duty cycle measurement
1. Set the function switch to the "Hz" position.
2. Insert the black test lead banana jack into the negative COM
jack and the red test lead banana plug into the positive Hz jack.
3. Touch the test probe tips to the circuit under test.
4. Read the frequency in the display. The digital reading will
indicate the proper decimal point, symbols (Hz, kHz, MHz) and
value.
5. Press the "MODE" button to display duty cycle in %.
