Resistance Measurement; Capacitance Measurement - Velleman DVM9915 Mode D'emploi

12. Resistance Measurement

Do not conduct resistance measurements on live circuits. Make sure
all capacitors in the circuit are depleted.
1. Connect the red test lead to the "VmA" jack and the black test lead to
the "COM" jack (the red lead has a positive polarity "+").
2. Set the rotary switch in the appropriate "
3. Connect the test leads to the resistor to be measured and read the
LCD display.
4. If the resistance being measured is connected to a circuit, turn off the
power and discharge all capacitors before applying the test probes.

13. Capacitance Measurement

Do not conduct capacitance measurements on live circuits. Make
sure all capacitors in the circuit are depleted.
1. Connect the red test lead to the "VmA" jack and the black test lead to
the "COM" jack.
2. Set the rotary switch in the appropriate "
3. Connect the test leads to the source to be measured and read the LCD
display.
4. If the capacitance being measured is connected to a circuit, turn off
the power and discharge all capacitors before applying the test probes.
Note that, when testing a 100 µF capacitor, there will be a time lag of
approximately 15 seconds.
14. Diode and Continuity Testing
Do not conduct diode or continuity measurements on live circuits.
Make sure all capacitors in the circuit are depleted.
1. Connect the red test lead to "VmA" jack and the black one to the
"COM" jack (the red lead has a positive polarity "+".).
2. Set the rotary switch in the "
3. Press "SELECT" and choose the "diode" or "continuity" measurement
mode.
4. Connect the red test lead to the anode of the diode to be tested and
the black test lead to the cathode of the diode. If the resistance is
lower than approximately 30 Ω, the buzzer sound.
5. If the diode or continuity being measured is connected to a circuit, turn
off the power and discharge all capacitors before applying the test
probes.
