Advanced LC meter




Description

After finishing my last project – “Simple LC meter“, there were some discussions in the forum I am a member of, that ability to measure electrolytic capacitors would be very useful in this type of device.

I searched the Web and found a very cute project named LCM3 on this Hungarian site: hobbielektronika.hu . I love Hungarian rock since my school days, but I don’t know a word in Hungarian πŸ™ . So, I searched the Web again, this time for this specific project and found a Russian forum where the project was discussed in details and I got more useful information about parts, settings and so on.

Advanced LC meter




Specifications of the LCM3 are (according to authors of the project):

Capacitors:

from 1pF to 1nF – resolution: 0.1pF, accuracy: 1%
from 1nF to 100nF – resolution: 1pF, accuracy: 1%
from 100nF to 1uF – resolution 1nF, accuracy: 2.5%

Electrolytic capacitors:

from 100nF to 100 000uF – resolution 1nF, accuracy: 5%

Inductance:

from 10nH to 20H – resolution 10nH, accuracy: 5%

Resistance:

from 1mOhm to 0.5Ohm – resolution 1mOhm, accuracy: 5%
