Set mode
Set mode is used to define which parameter (like load, torque, heart rate and linear constant
alpha) has to be adjusted during exercising in MANUAL mode with

keys
3.3.1
Hyperbolic
Hyperbolic mode means that the load P can be adjusted in watt. The load is kept constant
independent of rpm.
3.3.2
HR controlled
Heart rate can be adjusted and the load is regulated until the adjusted heart rate is reached.
This means when heart rate increases above the adjusted level load is decreased and the other
way around.
3.3.3
Linear
In linear mode the load 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.
3.3.4
Fixed Torque
In Fixed Torque mode the load is regulated such that the torque is kept at a set fixed value,
according to the formula:
T [Nm] = (P*60) / ( 2 *
π
* n [min
-1
])
Note: be aware of the fact that this fixed torque mode is not the same as the constant Torque
mode which is used with the Wingate software module (see for more information the Wingate
manual).
3.3.5
Isokinetic (only available for Excalibur Sport 925900)
In the Isokinetic mode the rpm is kept constant during the exercise, according to the formula:
P [W] = ( 2 *
π
* n [min
-1
]*T [Nm]) / 60
During the exercise you can not pedal faster then the chosen rpm. You can deliver more Force
with the same speed and produce more workload in this way.
Note: The rpm is the adjustable parameter in this case, this mode can be used to define the
optimal rpm.
3.4
Settings
Under settings all device specific and interface adjustments can be made. It concerns to all
those items not related directly to ergometry.
3.4.1
Default Startmenu
Normally your ergometer starts in the main menu. But you can modify this menu to your own
desired settings. This is convenient when your ergometer is used often in the same setting,
The following menus can be selected as startmenu: MAIN MENU; MANUAL; TERMINAL;
ANALOG At the next startup of your ergometer the selected menu will be activated.
