Linear
In linear mode the workload P is coupled with RPM using the following formula:
P [W] =
α
* (n [min
-1
]
)
2
The linear coupling constant
α
is the adjustable parameter in this case. The default value for
α
= 0.042 (giving for instance with 60 RPM a workload = 0.042*(60)
2
= 151 W). The unit of
α
is [W/min

] but it is shown dimensionless as a constant. Display during adjustment of
α

Fixed torque
In the Fixed torque mode the workload is regulated in such way that the torque is kept at an
adjusted fixed value, according the formula:
T [Nm] = (P*60) / ( 2 *
π
* n [min
-1
]
)
The torque T is adjusted in Nm:

Isokinetic (only available for Excalibur Sport 925900)
In the Isokinetic mode the rpm is regulated in such way that the rpm is kept at an adjusted
fixed value, according the formula:
P [W] = ( 2 *
π
* n [min
-1
]*T [Nm]) / 60
