For the x1 and x100 ohm ranges the 260 outputs 1.5 vdc, on the x10000 it outputs 9vdc! On the x1 range the short circuit current is 125 ma, on the x100 it¡¯s 1.25 ma, on the x10000 it¡¯s 75 ua. Danger, Will Robinson, danger!

Its a simpson 260, open to hearing any tips before i go in!
Some analog VOMs put out enough current to fry a mixer diode.
I did re-check, and I've since gotten more?problems in?this?area...? ? ? :-D? -10v supply is no longer happy..??
Lot of people saying it might be the mixer diodes, so I may check those w/ my old analog meter today after I look?
over MORE POWER SUPPLIES....? ??
Hi Bill,
?
When I first read your post I thought you did some very low frequency stuff.?
Actually you're referring to MHz (Megahertz), not mHz (Millihertz).
?
Since you left the unit running for a while until the fault condition appeared: did you re-check once it was cold again? Like after 24 hours?
?
cheers
