Supco MFD10 Digital Capacitor Tester with LED Display, 0.01 to 10000mF Range, 5% Accuracy

good

It works ok, I really just dont find it necessary. If you already have a quality voltmeter I find it faster and more accurate to use the reverse ohms law formula. If anybody didnt know already. (Amps x 2652.7)/(Volts) = Microfarats. I find capacitors (especially cheap ones) can have significant value change as they heat up in the circuit. You wont catch those testing them while they arent running. If you have a pile of capacitors to check that you dont have powered up, this tool could be useful.

Good

Work great

Was broke out of box, This chineese junk is a disgrace to the American working man.I am trying to make a living with my tools!!!

Good little tester, just be careful of the magnetic connection between meter leads and alligator clips.

Just as described. Quick shipping Thank you

As a RV tech, I use this tool to check the capacitors on all roof-top air conditioners. It significantly aids me to accurately diagnose electrical problems.

Great tool!! I would buy it again.

Saved me a bunch of money allowing me to repair the capacitor and check it correctly on my A/C.
