k) Capacity Measuring
Make sure that all circuit parts, circuits and components and other objects of measurement are
disconnected from the voltage and discharged.
Always observe polarity with electrolyte capacitors.
- Turn the DMM on and select measuring function
”Capacity”
- Plug the red measuring line into the Ω measuring jack (E)
and the black measuring line into the COM measuring jack
(D).
Due to the sensitive measuring input, the display
may show a value if the measuring lines are
“open”. By pressing the button “REL”, the display
is set to “0”. The autorange feature is deactivat-
ed. This is recommended for small capacities in
the nF range.
- Connect the two measuring prods (red = plus/black = mi-
nus) with the object to be measured (capacitator). After a
short time the display shows the capacity. Wait until the
displayed value has stabilised. This may take a few sec-
onds for capacities of >40 µF.
- If “OL” (overload) appears on the display, you have ex-
ceeded the measuring range.
- Remove the measuring lines from the object to be meas-
ured after completion of the measurement and switch off
the DMM.
