How many rpm's would 300g and 500g be? Thanks in advance!

To get 500g, assume that the rated speed is really 4000rpm and 1790g's - - then the answer is (500/1790)^0.5 X 4000 = 2114rpm. Rated rpm (4000) times the square root of the ratio desired. I would recommend using a digital tachometer to measure/achieve the rpm desired. Another purchase, but otherwise you will not have a clue to the real G level of the sample.
