6.2 Speed calibration
For Calibration of the Speed from the Valiant treadmill you can use a Tachometer which can
directly measure the speed at the walking belt.
A cheaper and even accurate method for calibration of the speed of the treadmill is counting
the revolutions of the belt. The belt length of the standard Valiant is 350 cm (137,8 ”)
Place a marker on the walking belt and count for two minutes how many times the marker
passes a certain point at several different belt speeds.
In the table you will find how many counts pro 2 minutes you should measure.

should be readjusted.
