[volt-nuts] Fluke 8502A

[Rob Klein]

Hi Steve,

I would just unplug all module except the controller. See if the display 
is normal, then plug the modules back in, one at a time (power-off/on in 
between, of course!). When
the display goes bad again, there's your culprit. Of course, if the 
display is bad with just the controller, well ... good luck ;-).

I have an 8505A myself, with a bad IEEE interface, which also causes the 
display to go mad. Haven't had the time to repair it yet, but no 
interface is not such a big deal.


Regards,
Rob.
