It's really hard to tell what the heck those photos are supposed to be,
but I do have the one with the metal stub on the mode selection switch,
which would be rev 11 or the new one, I think.

Comparison of a Rev 9 meter with a prototype Rev 11 meter.

So I just ran a test.

You did the water test, not the RF susceptibility test. Find a GSM
phone and see what it does. It wasn't my 87-V meter, but one of the
techs on a mountain top radio site announced that his meter was dead
and unusable anywhere near a source of RF. He sent it back to Fluke
for repair. I think (not sure) it was replaced by a later model.

As for waterproof, it appears that the 87-V is NOT waterproof. That's
the newer type 28 meter.

You can see there are two solder leads per jack. It seems that one side is
the "working" terminal of the jack and the other is just for sensing when
a probe is inserted because it will short out both pins. Inside the red
plastic jack each half terminal is just a nearly semicircle shaped contact
that wraps around almost half the banana-ish plug you's stick in there.

Reading from left to right on the above photo, that's:
+ terminal - terminal mA/uA Amps
While the mA/uA and Amps terminals have split pin connections, the +
and - terminals do not. I can see a possible problem with leakage
across the split terminals, but not across the + and - which don't
seem to have a sensor. My guess(tm) would be something is leaking
across the PCB, possible from the two Amps terminals to ground or
internal power. It might also be testing for any resistance between
the two Amps terminals, or between the Amp terminals and the +
terminal, which are unusable conditions.

Whatever they're sensing must be in the microvolts or microamps of leakage
between those half terminals. Whatever it is, it's way over sensitive.

True. Find a tiny o-ring that fits into the connector and cram it
down to the bottom until it seals the receptacle. That's should help.

Incidentally, I have two Fluke meters (Model 10 and 73). No problems
and well worth the money.
