so I got one of those $20 digital RPM meters for the table mill hooked it up per instru. and it will not hold a steady reading and jumps all over the place! >>>>>>>>>> have any experience with those??
yes fluorescent light above, ac/dc conversion to 12VI have heard those things can pick up electrical noise from nearby motor wiring. Does it flip around with nothing else on nearby?
(including fluorescent lights)
How are you powering it?

no sir.............magnetic pulse from a small magnet attached to metal draw bar`Is there a sensitivity adjustment(gain)?
the directions said 10 mm distance so I tried diffrent locations, no change as of yetDid you install the magnet in the proper direction? Also maybe try changing the air gap between the magnet and pickup I know I had this problem because the directions said one thing but found I needed less gap.
it could be that just not sure yet, will post wiring pixIt may be noise from the power supply or a grounding/shielding problem
Can you post pictures of the hardware?
