You
could use a paint on mask that you can get at hobby shop to protect the
mirror.

Greetings, recieved a 3406A sampling meter
free, now I need to
brushup on? what it is good for,? and what
benefits from sampling as
opposed to regular RF meters.
The question is
concerning those Hp meter faces from a certain era
that peel and crack at
the mirror ends (glued so well to brass
mirrored back and contraction
forces). There is a clear film that
flakes up and off over the lettering
and scale, the flaking stops at
the letters, as if that helps hold it
down. The stuff is water
soluable, so if it is wiped it smears. My 428B
meter also had this
same problem except letters below also were flaking,
had to photo
copy a new one, a pain since I tried dozens of copiers around
town
and found most could not copy at 100%,(laid ruler along side
meter face when copied so as to compare ), also cutting out a nice
mirror slot again is shunned.
The flaking has been nicely brushed off
and I would like to overspay
(masking the mirror) with something (even
water will remelt the film)
fast drying to prevent trouble below,
wrinkling etc. Anyone else have
ideas to save face. Iron on films are out
of the question since heat
on my 428B meter face caused fine cracks
everywhere like fine art
paintings.
Hopefully that is all that is wrong
with this meter since the lifting
film stopped the needle from
moving......... unless this occurred
after the probe was found to be
bad.
