Velleman Atlas ESR70 Capacitance and ESR Meter

This little meter kicks ass! Ease of use and accuracy. Well worth it!

As other reviewers have mentioned, this unit is far superior to the Chinese made unit for around $60. Just moving the capacitor with the leads attached made the ESR change tenfold. That meter did not give me the same reading when I checked the same capacitor several times in a row. It also did not hold zero each time. This meter, on the other hand, was made in England and is very consistent giving the same ESR every time and the capacitance on a 1300 uf capacitor just one or two uf difference at the most.

Works as described. I used it to repair a home air purifier that stopped working. I tested the capacitors while still on the circuit board, which experts will tell you doesn't work, but it allowed me to identify the faulty one.I replaced it and the purifier works again.

Pretty much foolproof. Just connect it to a capacitor, wait a few seconds, and it tells you the capacitance value and the ESR value. The microprocessor in it takes care of all of the work. It would be nice to have a Good/Bad ESR indication or a chart on the back.

I rarely write reviews unless a product totally needs recognition. This is the best Capacitor ESR meter that I have used. Truly saves you time by implementing in circuit testing. I have tried many Chinese capacitance testers and got fed up with the false data they presented so I broke the bank and bought this. Can’t say it was a bad purchase because it totally changed my life. I have cut my trouble shooting to 1/4 the time by having a unit that accurately tests in circuit. No more desoldering capacitors to test them. On rare occasions only you might have to lift a led to test. Simply accurate in every way. The best part is it discharges a capacitor before testing. This unit is a must for bench techs everywhere. Yea I know it is not cheap but I would not waste time with a review if it was useless like the TC1.

works very well runs tests very quickly and as far ai can tell ,would buy again if needed

Excellent design and accuracy. Super user friendly and saves battery. Old electronics use a lot of caps under 1uF, so the only con is it doesn't test under 1uF caps, hence the 4 star rating. The alligator clips are good quality. If you need different leads you need a female mini banana jack for the probes. I think it's 2mm.

Excelente equipo, me gustó desde que lo vi por primera vez.
