Technical Data
Alkaline Battery
AA batteries, quantity 4, (Energizer EN91) (NuStep part
number 41224). Note: If NuStep will not be used for more
than three months, remove AA batteries.
USB Port
The T4r console includes a USB host port for data transfer.
Note: USB port is for flash drive use only. Some flash drives
may not be compatible with the T4r USB port.
Standards
ANSI/AAMI ES60601-1, CAN/CSA-C22.2 No. 60601-1, IEC/EN
60601-1, IEC/EN 60601-1-2, EN 20957-1, EN 957–8 Class SB
Marks
Eddy current resistance system
The T4r features a speed dependent eddy current resistance
system that is dependent on workload level selected, the user
step rate and the user step length.
Range
0 - 800 watts
Stepping Action
The T4r features dependent stepping action with up to 8.5”
(22 cm) stepping range.
Watts Testing Parameters
Displayed watt values represent the energy consumption
rate of the user. They are calculated in real-time utilizing
an algorithm based on mechanical parameters of the
machine and a measured average ride style. The significant
mechanical parameters that influence the displayed
watt values include the inertia of the machine’s moving
components, the load level selected by the user, and the
rotational velocity of the eddy current disk. Validation testing
of the displayed watt values was performed by comparing
said value and the actual measured mechanical power
produced by multiple users. Displayed watt values are
independent of any physiological or anatomical parameter
possessed by the user.
