Ball 400 Series Variometer Manual

[Juan]

I've been looking for a shop to certify and if necessary overhaul a
Ball 400 series vario, and in doing so I found there are others
looking for the same. Since I saw some people concerned they have no
manual for this older vario, I thought I would make available the
manual included in the logs for my Aer Pegaso M100S.

If you need it, help yourself. Enjoy. :)

I have the original manuals for the vario and related audio.

However, I have given up on all diaphram Ball Varios. It is either
pressure xducer (700 series) or the trash can

aerodyne

Richard Ball finally hung up his tool kit a few years ago after decades of
taking care of these old variometers for owners.in their day they were good
instruments but their days have long passed and few of these will be found
without internal leaks or discrepancies anymore. I still have some data on
these but didn't even bother to post it on my "useful Information" page
since they are just not going to be repairable anymore without Richards
knowledge of their internal workings.and most parts for these have also gone
the way of the dinosaurs as well.....in this case it is time to move on and
get something newer.....

I'm well aware of the limitations of repairs on older avionics; I was
an avionics tech in the Marines in the late 1970's. I would at least
like to be able to test it to see if it works. If it does there's no
need to replace it until it doesn't. If it doesn't, then once the bird
is close to airworthiness it will be time to look for a replacement.
After all, it's installed on another dinosaur, an 1965 glider, that
one is has plenty of life left to it.
