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 on the readings from the ESR meter I would have replaced a perfectly good capacitor. I am debating purchasing another ESR meter now to check the ESR values returned. The instruction for this unit are for the 4.0 and they are awful.
