Frequently Asked Questions about the Tachometer

For example, if you want to set the diameter of the rotating body to 63.66 mm,
set DIAMETER to 636.6 mm,
and set the pulse factor (FACTOR) to 1.00000x10E-1 (=1.00000x10^-1).

With the TM-3100, the following calculations will be performed
Circumferential speed (mm/s) = Measured frequency (Hz) ÷ Number of pulses x Diameter value (mm) x π x Pulse factor
Circumferential speed (m/min) = Measured frequency (Hz) x 60 ÷ Number of pulses x Diameter value (mm) x 0.001 x π x Pulse factor
