As per Philip's original post, _all_ AC ranges drop gradually. This is really not consistent with a faulty EAROM. Rob. Op 7-12-2012 13:19, Wim de Jong schreef: Dave, Thats the question. It depends on the quality of the cells where the AC calibration info is stored. I'm not aware of a

Phil, However contradictory it may sound, that is actually a good thing. Continuous failures are always easier to chase down than your gremlins. Tracing front to back should bring you to Mount Doom relatively quickly ;-) Kind regards, Rob. Op 13-12-2012 0:10, Philip Pemberton schreef: I

50V across 5GOhm is 10nA. Put a standard multimeter's 10MOhm input in series and you have 10mV per nA reading. Anything below 100mV is pass. My 2 eurocents. Rob Klein Op 13-11-2015 om 17:15 schreef Andrea Baldoni: Hello! I would like to measure insulation resistance of some defective load

Hmm, it appears that is true. I've just checked on both my 3456 and 3457 and they do indeed have a larger horizontal spacing. Interestingly, the spacing on the 3456 is slightly smaller than on the 3457. ⁣Met vriendelijke groet, Rob Klein verstuurd vanaf mijn smartphone​ Op 9 nov. 2017 19:48
