Count the rev's
This unit was the second one I purched from another supplier However this unit works very well and gives a good
showing of the revs the spindle is going at , I'am using it on a lathe and is just what I wanted ,Be carefull of the wiring in some cases there is no instruction so be sure before you wire up the unit, there are plenty of instructions on the internet.
