centrally on the toothed belt under the belt
tensioning setting piece. Keep a short distance between the probe and toothed belt.

4. Hit the toothed belt once with a narrow, heavy object, e.g. Allen key , to set it vibrating.
The toothed belt must be able to vibrate freely and must not touch the probe of the frequency
measurement device. For evaluation of the toothed belt pretension, perform several measure-
ments to balance out any measurement tolerances.
Ä
The frequency meter shows the internal frequency of the toothed belt.
5. Compare the measurement result with the frequency setpoint value.
