I've gotten good advice here in the past. Maybe someone can help
me with this problem

I have a rather expensive oven mercury thermometer. When using it
in a combination MW/convection oven with a rotating surface to
test the oven temperature, evidently the vibration caused the
mercury to be widely scattered thoughout the glass column.

Vibration? *What vibration?

From the round rotating surface inside the MW oven.

Does your oven vibrate like a paint mixer? *I've
never seen any vibration on a rotating base inside a microwave that
had any significant vibration. *They turn
at like 3 RPM. *I don't see how that could account for
mercury seperation in a thermometer.

The turntable rides on little plastic wheels. It runs on a surface. It
has a motor. Evidently one or more of these is a little bit rough and
causes a slight vibration. Normally not noticable, but it possibly
affected the thermometer if it is very sensitive to such movement.



If the microwave was active,

It isn't when the convection oven is in use.

Maybe I'm wrong, but I thought these ovens allowed you
to use both at the same time. *Some I though just used
MW for heating combined with a fan for convection, *Others
I thought added other conventional heating elements
together with the convection.

Mine has three modes - mw, oven and both. I am discussing the oven-only
mode which uses a heating element.











I would think THAT would screw things up big time. *Mercury
is a metal you know....

I read a site info on this problem
but none of their suggestions helped. Tapping it into my hand to
move the mecury, heating it, etc.

The only other idea I have is to somehow fasten it to an electric
drill a
nd
spin it so the centrifugal force forces the mercury to the bulb
but can't figure out how to securely mount it.

Any better ideas?

TIA

No, but the drill idea sounds like a very bad one. *Unless you
want broken glass and mercury contamination all over the place

That's why I said 'securely'.
