Re: 2 wire hall sensor / Tachometer

I did try the multimeter, got milivolts turning by hand, can’t power it up without the controller, and the controller won’t ‘control’ without hall sensor input.

It’s ok I’ll buy one, I’m not going to mess around building a filter and OP amp circuit for this.

Thanks Seamy
