The next time I get one, I'll mail it to you.


My advice is solid, only a raving nut case would REMOVE every electro from circuit in order to test the C value when the * in circuit* ESR reading was good.

Do you ?

I don't really use the ESR meter much anymore, just for morbid curiosity after the fact really. Scopes are much faster. Plus, there are circuits that will fool ESR meters into showing perfectly good caps when they are actually close to being exhausted. Anybody who's ever rebuilt a Mitsubishi format or DM board with the half dozen dc-dc converters on board has seen this.
