h) Capacitance measurement
Make sure that the circuit components, circuits and components to be meas-
ured or any other measuring objects are voltage-free and discharged.
In the case of electrolytic capacitors, observe correct polarity.
- Turn on the DMM and select the measuring range
- Insert the red test lead into the V test socket (10) and the black
test lead into the COM test socket (9).
- The display shows the unit "nF".
Due to the high sensitivity of the test input, you may en-
counter a low display value in the case of "open" test
leads. Puss the REL key twice to set the display to "0"
and deactivate automatic range selection. The smaller
upper display shows the basic value (relative difference).
The REL function is thus only of any use in the case of
low capacitance values.
- Now connect both test prods (red = positive pole / black =
negative pole) to the measuring object (capacitor). The display
shows the capacitance after a brief period. Wait until the reading
stabilizes. This may take several seconds in the case of capaci-
tances >60 μF.
- You have exceeded the measuring range when the display shows "OL" (for overload).
- Remove the test leads from the measuring object and turn off the DMM after measurement.
