12.11 Measuring capacitance
Make sure that all objects that you wish to measure (including circuit
components, circuits and component parts) are disconnected and dis-
charged.
1. Switch on the DMM and select the mode
.
2. Press
SEL
/
3x to switch to capaci-
tance mode.
Æ
“nF” will appear on the display.
3. Plug the red lead into the
V
terminal and
the black lead into the
COM
terminal.
Due to the sensitive measuring in-
put, a value may appear on the
display when the measuring leads
are “open”. Press the
REL
button
when measuring small capacitanc-
es (<400 nF). The display will be
reset to “0” and the auto-range
function will be disabled.
4. Connect the two test probes (red = positive, black = negative) to the object
that you want to measure (condenser). The capacitance will be shown on the
display after a few seconds. Wait until the display stabilises. This may take a few
seconds for capacitances greater than 40 µF.
Æ
“OL” (overload) indicates that the measuring range has been exceeded.
5. After taking a measurement, remove the leads from the measured object and
switch off the DMM.
