Analysing Capacitors continued
The ESR analysis typically takes under 2 seconds to complete, followed by up
to around 10 seconds for the capacitance measurement (depending on the
characteristics of the capacitor).
As soon as a valid ESR reading has
been obtained, the ESR value is
displayed while the instrument
proceeds to measure the capacitance.
If the presence of external circuitry did
not adversely affect the capacitance
measurement, the capacitor value will
be displayed.
If the capacitance could not be
determined (perhaps it is in-circuit or a
“leaky” capacitor), the display will only
show the value of ESR measured.
It is not necessary to wait for the capacitance measurement to complete if
you’re not interested in the capacitance value. If the probes are removed from
the component under test before the
capacitance measurement has
completed, the display will confirm that
the capacitance has not be measured:
It can be useful to disconnect the probes before the capacitance measurement
has completed if you’re wanting to simply check the ESR of multiple
components in succession.
