6.5. Continuity testing
CAUTION! Measurements must only be made with the circuit power OFF.
1. Set the rotary switch to the  position.
2. Plug the black test lead to COM-input and the red test lead to the
 ) ) )
3. Select the function by pressing the MODE-button.
4. Connect the probe tips to the circuit or device under test, making sure it is de-energized first.
5. An audible tone will sound for resistance less than approx. 50 .
6. After all measurements are completed, disconnect the test leads from the circuit and from the
input terminals.
6.6. Diode testing
CAUTION! Measurements must only be made with the circuit power OFF.
1. Set the rotary switch to the  position.
2. Plug the black test lead to COM-input and the red test lead to the
3. Select the
4. The red test lead should be connected to the anode and the lack lead to the cathode.
5. For a silicon diode, the typical forward voltage should be about 0,7 V or 0.4 V for a germanium
diode.
6. If the diode is reverse biased or there is an open circuit the display shows "OL".
7. After all measurements are completed, disconnect the test leads from the circuit and from the
input terminals.
