Hi guys,
Sorry to hack the tread, but I been offer from an friend of mine, for few euros, an 3456 with error 4 OL in all the ranges, and another with intermittent readings with no relation.
I've look at the manual and troubleshooting list for error 4, they ask for an Signature analyzer, witch I don't have, will this be worth the trouble to dive in to this and look at it with an DMM only?
Or should I stay away from it?
