Digital Tachometer Problems
#1
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?
