6.4. Continuity testing
1. Select the
2. Follow step 2 and 4 as for resistance measurements.
3. An audible tone will sound for resistance less than approx.
35
(P 1625) or 100 (P 1610/P 1615). After all
measurements are completed, disconnect the test leads
from the circuit and from the DCM input terminals.
6.5. Diode testing
CAUTION!
Measurements must only be made with the circuit power
OFF.
1. Set the rotary selector switch to the
2. Follow steps 2 and 4 as for resistance measurements.
3. The red test lead should be connected to the anode and the
black lead to the cathode. For a silicon diode, the typical
forward voltage should be about 0,7 V or 0.4 V for a
germanium diode.
4. If the diode is reverse biased or there is an open circuit the
display shows "OL".
6.6. Capacitance measurement
1. Turn off power to the device under test and discharge all
capacitors.
2. Discharge all voltage from the capacitor before measuring its
capacitance value.
Note: A safe way to discharge a capacitor is to connect a
100 k resistor across the two capacitor leads.
3. Set the rotary selector switch to the capacitance range.
4. Plug the black and red test leads into the COM and V/
input terminals respectively.
