We tried for wave today and all we got was high on the engine. Since I
was in smooth air, I tried pushing over and pulling up and found the
Winter mechanical vario in my Stemme to be very well compensated.
Likewise the CNv was well compensated. Checking its setup, I found that
it is set for electronic compensation, I did not look at the percentage.

Thanks Evan, I was gonna try that. I already have the TCs set at 0.5
sec. I'll report back if I see any difference.

Mechanical varios don't play well with modern pressure transducer
type varios and should not share TE sources with them.

I have a 57 mm Winter mechanical and a CNvXC connected to the triple
probe in my Stemme. The needles on each track perfectly with each
other.
Which illustrates what goes wrong :-).

The effect of the mechanical vario is to slow the whole system down
to its own speed.

If you are using the triple probe pitot and static for CNv's pitot
and static inputs, and the static source is not shared with any
mechanical instrument (pitot source may be shared with an ASI since
the pitot aneroid volume is small), try setting CNv to "no probe" and
see if you don't like the response of the instrument better. I
suggest setting the audio & pointer time constants to 0.5 sec.

best,
Evan for CNi
