Reply to "Pseudo tach for variable input speeds"

I can't say specific to 2140, but in the olden days:

Do you have a tachometer on the motor shaft? If yes, then for machine setup choose Enter Speed only Once =  No, and Check/select on Fixed Tach Location

The Motor shaft speed Reference and each measurement point Reference (ratio accordingly) are part of the Measurement Point setup.

The intermediate measurement points on gearbox would then have the speed ratio to the actual motor speed. It would be wise to make all measurements on machine at close to the same motor speed; during one survey and repeated surveys. The old apples-to-apples comparison game!
