Ok beru zpět, omlouvám se. Asi se v tom vyznáte, každopádně mám multimetr, který umí měřit frekvenci a kapacitu kondenzátoru, teda alespoň podle specifikací:

[spoiler]Auto Range.
True RMS measurement.
Resistance capacitance frequency file high voltage 550V protection.
Large screen display, the maximum of 6000 words.
Sampling rate: about 3 times per second.
Temperature measuring.
Data retention.
Polarity automatic recognition.
Low voltage display.
10A large current measurement MA level small current measurement Automatic shutdown.
Main measurement: AC / DC voltage, AC / DC current, resistance, capacitance.
Diode / off measurement, frequency and duty ratio measurement.

Measurement mode: double-integral style A/D transform
Sample rate: 3 times per second
Over range indication: OL
Powered by 2 x AAA batteries (Not included).
Working Environment: 0-40 degrees relative humidity: <80%
Frequency measurement range: to 10MHz 1Hz
Temperature measuring range: -20℃ to 1000℃ (-4℉ to 1832℉ )
Capacitance measurement range: to 6000uF 10pF
AC voltage measurement range: to 750V 0.1mV
DC voltage measurement range: to 1000V 0.1mV
AC current measurement range: to 10A 0.1uA
DC current measurement range: to 10A 0.1uA
Resistance measurement range: 0.1 60M to
Width ratio measurement range: 1% to 99% [/spoiler]

Takže, zdroj nechám vypnutý a změřím hodnotu jednotlivých kondenzátorů? Když bude špatná tak přepájet?

díky ještě jednou a omlouvám se
