Once you understand the timing cycle, you can test down to 0.5uf and up to 650uf.

It can test large start and run capacitors as well as 1uf miniature capacitors rated at 10v. Most multimeters don't have this function, though, but you can still test a capacitor using the voltmeter or ohm meter setting. De-energize and discharge the circuit completely before connecting a megger. In case your capacitor is polarized, then you have to put the black lead on its negative terminal. Some multimeters measure capacitance directly by supplying a voltage across a capacitor and measuring the discharge current.

Never touch the test leads while the handle is being cranked. Measure capacitance and dissipation factor with precision For transformer manufacturers, test laboratories, power utilities and others with a need to measure capacitance and dissipation factor at high voltages, Megger's new CDAX 605 test set provides a convenient, cost-effective and versatile solution. This simple capacitor tester is capable of testing electrolytic capacitors in the range of 1uf to 450uf. Take the black (negative) lead of your ohmmeter and put it on a terminal of the capacitor. Use megger on high-resistance measurements only, such as insulation measurements or to check two separate conductors on a cable. If you suspect the capacitor is dead, conducting an ohm meter test is the easiest way to find out. In case it is a dual capacitor that you are testing, put the black lead on its “COM” terminal.
