Greetings All,
I was given an old meter that was originally bought by the US
government. It was missing some labeling so I don't really know yet
what all it can do. It can measure some kind of radio signal (I think)
because it has a probe that connects to the kind of fittings I've seen
on radio gear. The fittings are large co-axial and the probe plugs
into the fittings. The probe for this has some kind of tube (valve for
the Brits) in it with a metal point coming out of the end which makes
contact with what looks like a gold plated piece of bent flat spring.
I know this is not a very good description and I will be posting
pictures of it on the Metalworking.com web site. This device is about
6" x 9" by 8" tall. It had gotten wet so I took it apart to dry out
the internals. The meter movement seems to have stayed dry but other
stuff inside got wet. Inside the thing are two what I think are NE3
neon bulbs. The sockets for them are marked NE3. I was able to find
some on the internet for sale but no pictures. I have two questions
about these bulbs. First, since any light coming from these would not
be visible when using the meter what could their purpose(s) be? And
second, how can these bulbs be re-glued into their bases? I was going
to remove them from the sockets to clean the contacts in the sockets
but the glass bulbs are loose in the brass bases. I could buy new ones
but at anywhere from 9 to 15 bucks apiece, plus shipping, it's too
much money to spend on something that I don't know will even work when
plugged in. For that matter the meter is might release all it's magic
smoke when plugged in the first time. It's interesting that the power
supply section is made to be swung out when the case is removed from
the meter. Printed on the chassis inside are instructions to remove
two particular screws to pivot open the power supply.
Anyway, thanks for any help and insights.
Cheers,
Eric R Snow
