Default How do I rig a netto variometer

It is mechanical, has two ports on the back, one says static, other
capacity. Emblem on front has a A W written on it. I know it's more
complicated than just plugging in the static line and the capacity
line.


but it is.....that simple.. the "W" in the face is "Winter"
...if you want to use it as a basic mechanical variometer as it was
intended....connect to static or TE (TE is simply a "compensated" Static and
connect the other side to the proper size capacity bottle.....keeping in
mind that especially these very odd range variometers can and usually do use
a .90liter, or even 1.8 liter capacity bottle and not the normal .45 used on
almost every other variometer.
also remember that if this is a very old variometer just becuase the needle
appears to move in the correct direction doesn't mean it's any where close
to be accuarte anymore, most of these older instruments really need to be
overhauled even when kept in reasonibly good storage after 15-20 years old.
I see these all the time that are closer to 40 years old and the needles
move..but far from the way they were intended.

Not wanting to use it as a simple vario. I like the netto
idea.
