Working in the field today and demonstrating how to test a capacitor. ALWAYS discharge the capacitor before touching the terminals, a capacitor has the ability to release 100% of its stored energy in picoseconds. Your fingers will get a nasty reminder if you forget, or burn up a diagnostic tool.
We test a start capacitor and a run capacitor with dual storage.
Capacitor spec typically have a 10% leeway to be acceptable for use.
The tool is a Supco MFD 10. They last for many years if you replace the battery before it corrodes. I replace the batteries in all of my meters and diagnostic tools yearly as PM.
