How to Measure Your Machine's RPM ACOEM USA

*Note: If your machine is a VFD, then you will need to use the expected RPM on the shaft. An example to keep in mind is that if you have a machine with an expected RPM of 1765, a good number at which to set your stroboscope or tachometer would be 1800. Next, find something that you can pinpoint on the machine, such as a bolt hole. Turn the machine
