Re: add-on capacitance meter circuit

It will be a while before I can get around to trying it but, when I do, I plan on using one of those spring loaded speaker terminals for holding 'Cx' - the kind you find on low end, cheap speakers where you push in a button, insert the wire and release the button to grip the wire. This should provide a more positive connection and has the advantage of being colour coded also.

Re: add-on capacitance meter circuit

Many thanks for posting the documents.

I've just skimmed through the article and, on paper, it looks to be ideal for my purpose. I'll gather up the bits and pieces (not sure if I have a 74HC132 to hand at the moment) and give it a go ASAP.
Oh, and thanks for the rar. files - I'll print off a copy.

Re: add-on capacitance meter circuit

Thanks for the reply.

I cannot find any info on the Electronics Australia kit online. If you have the time to send it in a PM, I would be interested in having a look at the circuit diagram.

Hi all,

First post on here.
I want to build a simple capacitance meter that I can use with my DMM. It doesn't need to have ultra 'lab' accuracy as it will mostly be used for measuring caps for use in speaker crossover circuits and very occasional, general use.
Most of the circuits I have seen on the 'net are either too complex (and costly) PIC based or don't have the range I need. Some years ago I built an LC circuit that covers the lower ranges up to 2uF so really I would like build something to measure from 2uf to (say) 100uF.

I would be grateful for any...
