Constant Engine RPM
With the operating mode
Constant Engine RPM the dyno is regulated in such a way that the
engine RPM remains constant independent from the traction and speed created by the vehicle.
The pre-selected target value (n-target) is regulated independent from the traction created by the
vehicle up to the max. dyno motor capacity.
1 Position the vehicle on the dyno and fix it.
