calibration capacitor

[peter g]

hi, i've completed the construction of an esr meter.and need to calibrate it. to do this i need someone who has access to a really accurate cap value reader. i need someone to test the actual value of a 470mfd. cap. and send it to me. i will gladly pay for any expense. thanks all.

hi all, well i finished construction and programmed the hex code into the micro. this meter measures esr and capacitance at the same time in circuit. just need to calibrate.

I got your PM. Just shoot me a few rough ranges and I'll get you some caps out in the mail.

range from 470 to 1000mfd.

Are you saying Milli Farads of Micro Farads?

micro farads. uf

OK, I'll dig through a few and get a reasonable range spread. Give me a few days and as soon as I get them out I'll shoot you a PM with a USPS tracking number. I'm in Cleveland, Ohio so figure several days to you.

o.k. ron, thanks much.

I sent you some random caps measured with a precision bridge. Sorry I am a little late. Had a few unexpected issues including my home PC threw up. I mailed them USPS so give them a few says.

The caps are taped to a paper with the actual values written below each cap. I also sent you a PM. Again. apologies for the delay.
