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.
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.
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.
