How These Modes are Different
MEDICAL AND ERGOMETER MODE
96
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 Z8
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 6 for manual operation and
Chapter 10 for custom program operation.

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
newtons. 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.
