Measuring Capacitance - VOLTCRAFT VC-890 Bedienungsanleitung

h) Measuring capacitance
Make sure that all circuit parts, switches and components, and other objects of
measurement are disconnected from the voltage and discharged at all times.
Always observe the polarity for electrolytic capacitors.
1. Turn on the DMM and select the measurement range "
2. Insert the red test lead in the °CHzVΩ measuring socket (7),
the black test lead in the COM measuring socket (8) (Fig. 8).
3. The unit "nF" will appear on the display.
Due to the sensitivity of the measuring input, it is possible
that a value is displayed when the test leads are "open".
Pressing the REL/PC (Log/◄) button (10c) will set the
display to "0". The base value (Rel difference) is displayed
next to the delta symbol
deactivated.
4. Now connect the two test prods (red = plus pole/black = minus
pole) with the object to be measured (capacitor). After a short
while the display shows the capacitance. Wait until the display
has stabilised. For capacitances >400 μF this may take a few
seconds.
5. If "OL" (for overload) appears on the display, you have exceeded the measuring range.
6. After the measurement has been completed, remove the test leads from the object being
measured and turn the DMM off.
