The two modes differ in the way they control workload:
Ergometer Mode: This emulates
a popular cycle ergometer whose
workload settings are in kiloponds
(see side bar) and are adjusted by
changing the amount of weight (in
kilograms) at the end of a brake belt
wrapped around a flywheel.
Many testing protocols are written
especially for such an ergometer.
These protocols can now be run on
the CS 8.0 Bike, either programmed
into a custom program or run
manually.
Medical Mode: This uses either
METs or watts, instead of kiloponds,
for workload control. (Although
that’s just like normal operation mode, Medical mode adds the
previously mentioned useful functions like no torque roll-off and
rpm limiting, and doesn’t allow riders to play around with other
exercise modes.) Most exercise prescriptions are in either METs
or watts, so this mode is useful for that.
These modes restrict operation to manual and custom programs.
Refer to Chapter 5 for manual operation and Chapter 9 for
custom program operation.
Change the pedal RPM limit in Setup Mode.
What’s a kilopond?
This is an obsolete unit
of force, equivalent to the
gravitational force on one
kilogram at the earth’s
surface, or about 9.8 new-
tons. Sweden made the
kilopond its official unit
of force in 1945, and thus
it ended up being used
in an ergometer made in
Sweden. It is essentially
equivalent to the force on
a kilogram at the Earth’s
surface.
