6.2 Speed calibration
For Calibration of the Speed from the 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 belt 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.

Table 1
The values should be within 5%. The motor speed is absolute the motor is frequency
controlled and a difference in speed could only be caused by sliding of one of the belts. E.g.
the belt from drive motor to drive roller or the walking belt itself.
