Diode Test
1. Set the Function switch to the diode position.
2. Press the FUNC key until the symbol appears on the LCD.
3. Insert the black test lead to the COM input jack and the red test lead to the input jack.
4. Connect the test lead tips to the diode. A typical diode forward voltage drop will indicate 0.3
to 0.7V. The reverse drop will indicate "OL", indicating high impedance. Proper diode check
should include both forward and reverse tests.
Frequency Measurement
1. Set the Function switch to the Hz position.
2. Press the FUNC key until the "Hz" symbol appears on the LCD.
3. Insert the black test lead to the COM input jack and the red test lead to the
Hz input jack.
4. Connect the tips of the test leads to the device to be measured (see
diagram).
5. Read the frequency value in Hz on the LCD.
Duty Cycle Measurements
Follow the steps as for Frequency measurements with the following exception: Press the âHz/%â
key until the â%â symbol appears on the display.
Capacitance Measurement
1. Set the Function switch to the position.
2. Press the FUNC key until the "nF" symbol appears on the LCD.
3. Insert the black test lead to the COM input jack and the red test lead to the
red input terminal.
4. Connect the tips of the test leads to the device to be measured (see
diagram).
5. Read the capacitance value on the display.
NOTE: When making very low capacitance measurements, use the REL function
to zero any stray capacitance.
