Hi Meat Plow,
Yes, that procedure works for a while (a year or so), but eventually,
it
has to be done again.

Hi Meat Plow,
That is what I have done, but I use a special cleaning 100% alcohol
I
ordered from MCM Electronics years ago.

Well I assume it worked out ok for you. We used to use a 100% alcohol
for swabbing tape heads back in my days as a warranty service tech for
Circuit City's mobile audio stuff.

Hi,
Back in 1995, I bought a Fluke "12" Multimeter (digital) because
of a
special feature (Max & Mim) it has. I have not used that meter often
over the
years, unless I needed to use that special feature.
I have a display problem. Not all the segments of a digit are
"active".
I had worked on this problem more than once over the years. The
display
panel has those problematic edge contacts.
Does anyone know of a good fix for this problem?
Thank You in advance, John
PS, Remove "ine" from my email address
If you remove and clean the edges of the display and all the contact
points and its connections to the board with 90% alcohol with a
lintless swab that should restore the display for another few years if
not longer. I've done this to my Fluke 77 twice in the 20 years I've
had it.
The rubber permanently relaxes so you have to narrow the spacing/ increase
the closure force, ISTR running a film of solder over the pcb lands in one
such case, otherwise change/cut back any spacing arrangement, ie not
increased pressure on the glass
