Tronic "old" AMC 1.5

Hi, I have to ask about the multi-turn potentiometer, for what is it for? I never really used this, always let it alone but it should be somehow useful.

Ok Thanos, thanks!
Now I get it. I did the experience and works just like you said.

Altought it is useful, IMHO I prefer full clockwise position. I will explain:
With this multi-turn full clockwise, we have 1024/4=256 bit to my 90 degree pot course. Which means 2,84 bit per degree (lets say 3 bit per degree).

With this multi-turn tunned for 90 degree pot, we have 1024 bit to my 90 degree pot couse. Which means 11,3 bit per degree (lets say 12 bit per degree).

So if the x-sim software "tells" AMC to move 24 bit to one direction, then the simulator pots will need to turn 8 degree to do it, in the non-tunned way, and 2 degree when tunned.

The pratice result here for the "tunning" was more fidget movement as the pots now are much more sensitive to even to the smaller interference in positioning.

And, my conclusion is that it will be much better with the optical position sensors, which may be accurate enough even with small 2 degree courses.

regards!

tienen idea si puedo conectar esta palaca
y como conectarla ala AVR1.5

They have no idea if you can connect this lever
and as a connecting wing AVR1.5
