Re: ESR-Micro v5.0

330 uf capacitor ESR value according to the chart is .25 which is good now. I thought 10% on the capacitance was the magic rule - if 20% then no problem and I guess I will disregard the difference between the two meter readings - thank you for the feedback.

Re: ESR-Micro v5.0

Diff, I did re calibrate and the ESR dropped to .25 and the UF came up to 295 uf. Still lower than the Fluke reading of 313 uf. Not sure about the accuracy of what so I going to get a hold of another ESR meter and compare.

Re: ESR-Micro v5.0

Thank you, I did read the calibration piece and I will try that for the probes again. The other part of the calibration for removed capacitors seems confusing.

I purchased an ESR-Micro v5.0 after reviewing a lot of positive feedback. I am new to electronics and please excuse me if I come off as a little green because I am. Anyway, after unpacking the ESR I decided to test it on a new capacitor, 330 uf 25v. The readings although they tended to keep changing all over the place average 284 uf and an ESR value of .55. I thought this was suspicious so I checked the uf readings with my Fluke 87v and they came back at a solid
313 uf. My question is does anybody know if this instrument needs to be calibrated or is this margin of error acceptable. Based...

Hello to all, my name is Dave and I am getting close to retirement and always had an interest in electronics and trouble shooting malfunctioning items from battery chargers to stereos. I have started assembling equipment, multi meters etc, and have questions.
Best.
