3. When checking in-circuit resistance, be sure the circuit under test has
all power removed and that all capacitors are fully discharged.
6.7. Capacitance measurements
Caution!
Turn off power and discharge the capacitor before attempting a capacitance
measurement. Use the DCV function to confirm that the capacitor is
discharged.
1. Set the Function switch to "CAP"-position.
2. Connect the red test lead to the V/Ω -input jack and the black test lead
to the COM-input jack.
3. Connect the test leads to the capacitor. Observe polarity when
measuring polarized capacitors.
3. Read the capacitance

indicate near zero on all ranges.
6.8. Diode Measurement
1. Connect the black test lead to the COM jack and the red test lead to
the V/Ω - jack. (Note: the polarity of the red test lead is "+")
2. Set the function switch to the "Ω/
3. Select Diode-function by pressing "MODE"-button.
4. Connect the test leads across the diode under measurement.
