RPM Multiplier
In the case of a gearbox that increases or decreases the
speed of the driven machine relative to its driven input
speed, this entry will account for the speed changes of the
driven unit based on the tachometer reading or input at
the time the measurements are recorded on the driver.
Diameter of Roller/Pulley
Similar to a RPM Multiplier, for belt driven machines the

diameters for the driver pulley and driven pulley are
measured and entered. From that point on, only the
