- After measuring, remove the measuring leads from the measuring object and
turn the meter off. Turn the rotary switch to „OFF“.
f) Capacity measurement
ƽ
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“.
