Pitch wheel goes down, but not up

[laandodeman]

Since a few days, my pitch does not respond anymore when I turn the wheel up. When I turn it down, it works fine.

Hardware problem?

It sounds like you need to calibrate your wheels, which is outlined in this post: http://forum.davesmithinstruments.com/index.php/topic,162.msg2118.html#msg2118
