I ordered a Chinese digital tachometer to use on my mini mill (DT-2234C+). It had a lot of good press and it was cheap, so I figured I'd try it. I thought I would use it to mark RPMs by the hundreds on the variable speed control dial. This is it:
Well, it lights up, a laser shoots out the front, but every reading is 0 RPMs. This diminishes its worth considerably. I was wondering if I am doing something wrong? Does anybody have any experience with one of these?
