Thread: VFD Pot Dead Zone

I’m glad you got it working but I am confused with some of your settings.

So am I! After you put me on the right track I decided to push my luck further aiming for an overall range between 25 and 90Hz AND with my preferred working range of 50 to 60Hz at the middle of the dial (top dead centre). This wouldn't have been necessary a few years ago as I had a good idea of the speed by the sound, but my hearing is now at the stage where I have to look at a dial or display panel. It may all be unorthodox but it works for me, so thanks again for pointing me in the right direction.
