H) Conducting A Continuity Test; Diode Test - VOLTCRAFT VC-532 AC Bedienungsanleitung

h) Conducting a continuity test

Make sure that all objects that you wish to measure (including
circuit components, circuits and component parts) are discon-
nected and discharged.
• Switch on the DMM and select the
display.
• Press the "MODE" button to switch measurement modes. The continuity test
symbol will be displayed. Press the button again to switch to the next measur-
ing mode.
• Plug the red lead into the V terminal (K) and the black lead into the COM
terminal (I).
• An approximate value of <50 Ohm is recognized and you will hear a beep. The
continuity test measures resistances of up to 600 Ohm.
• "OL" (overload) indicates that the measuring range has been exceeded or that
the circuit is broken.
• After measuring, remove the test leads from the measured object and turn the
multimeter off.
i) Diode test
Make sure that all objects that you wish to measure (including
circuit components, circuits and component parts) are discon-
nected and discharged.
• Switch on the DMM and select the
• Press the "MODE" button to switch measurement modes. The diode test sym-
bol and the V unit will appear on the display. Press the button again to switch
to the next measuring mode.
• Plug the red lead into the V terminal (K) and the black lead into the COM
terminal (I).
• Check the measuring leads for continuity by connecting both measuring
probes to one another. A value of approx. 0.000 V should be shown.
• Connect the measuring probes to the object that you want to measure (diode).
• The continuity voltage ("UF") will be shown in Volts (V). "OL" indicates that the
diode is reverse-biased or defective. Try taking the measurement again in the
opposite polarity.
• After measuring, remove the test leads from the measured object and turn the
multimeter off.
