H) Capacity Measuring - VOLTCRAFT VC-540 Bedienungsanleitung

h) 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.
- Switch on the DMM and select measuring range "
- Plug the red measuring line into the v measuring jack (9) and the black measuring line into
the COM measuring jack (8).
- The display shows the unit "nF".
Due to the sensitive measuring input, the display may show a low value if the measuring
lines are "open". By pushing the button "REL", the display is set to "0" and the auto
range function is deactivated. The REL function is therefore only sensible at low capaci-
ties.
- Now connect the two measuring prods (red = plus/black = minus) 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 seconds for capacities of >50 µF.
- If "OL" (overload) appears on the display, you have exceeded the measuring range.
- Remove the measuring lines from the object to be measured after completion of the meas-
urement and switch off the DMM.
