Thanks, everything is okay, now I hope it will works ;-)

Yep right, my formulas use radians/volt, so, how can I transform the
hz/v
value that I got with your trick, to rad/v ?

omega = 2*PI*f

that's where the 6:1 came from. 8-)

One cycle = 360 degrees = 2*pi radians, which makes
radians/volt = 2*pi*hz/volt.
