turn the meter off. Turn the rotary switch to „OFF".
f) Capacity measurement
Make sure that all the circuit parts, switches and components
and other objects of measurement are disconnected from the
voltage and discharged.
With electrolyte capacitors, observe the polarity.
- Turn the meter on at the rotary switch and select the measuring range CAP.
- Insert the measuring leads to the measuring instrument in the same way as for
resistance measurement.
- To activate the capacity measurement function in the VC521, press the „MODE"
key (7) three times.
- The display shows the unit „nF".
Due to the sensitive measuring input, the display may show a value in
case of „open" measuring leads. The display is set to „0" by pressing the
„REL" key,
- Now connect the two test prods (red = positive pole/black = negative pole) with
the object to be measured (condenser). After a short while the display shows the
capacity. Wait until the display has stabilised. With capacities of >40 μF, this
may take a few seconds.
- As soon as „OL" (overload) appears on the display, you have exceeded the mea-
suring range.
- After measuring, remove the measuring leads from the measuring object and
turn the meter off. Turn the rotary switch to „OFF".
