on is selected. Pressing the "SET" key again switches operation
back to speed-independent. If the training is interrupted, the dis-
play computer automatically switches back to speed-indepen-
dent operation.
For speed-dependent operation, power has no upper or lower
limit. If with a power of over 600 W, operation is switched
back to speed-independent, the power display is set to 600 W,
and the braking toque is changed respectively. If with a power
display of below 25 W, operation is switched back to speed-
independent, power is set to 25 W, and the braking torque is
changed.
Speed-dependent operation (Count Up, Count Down)
Speed-dependent operation is available during training only. If
there is a switchover to speed-dependent operation, the braking
torque is kept constant. The displayed power is not changed,
until the pedaling speed is changed. With a change in speed,
the current power is calculated from the (constant) braking tor-
que and the current pedal speed, and displayed respectively. If
the power displayed in speed-independent operation is not sett-
able (arrow symbols are shown), the actual power value is dis-
played in the moment of switchover. The power can be chan-
ged by means of the "+" and "-" keys or by means of speed.
During training, the displayed power is increased or decreased
in 5 W (or 25 W, respectively) steps with the "+" or "-" keys,
respectively. For that, the current power is taken as standard.
The new braking torque is calculated and set. Then the braking
torque is kept constant, and the power display is calculated
anew for changing pedal speed like described above.
A change of the ergometer power by means of the "+" and "-"
keys is only possible in the range from 25 W to 600 W. If a
key outside this range is pressed, the display jumps to the next
possible value within the determined limits and the braking tor-
que is changed respectively.
Energy
Calculates the energy turnover of the body with an efficiency of
25 % to provide the mechanical power. The remaining 75 %
does the body convert to heat.
Fat burning pulse
Calculated value of: 65% MaxPuls
Fitness pulse
Calculated value of: 75% MaxPuls
Glossary
A collection of attempts for explanation.
HI symbol
With "HI" displayed, a target pulse is too high by 11 beats.
With HI blinking, the maximum pulse is exceeded.
LO symbol
With "LO" displayed, a target pulse is too low by 11 beats.
Manual –
Calculated value of: 40 – 90% MaxPuls
MaxPulse(s)
Calculated value of 220 minus years of age
Menu
Display in which values are to be entered or selected.
Power
Current value of the mechanical (braking) power in Watts,
which the ergometer converts into heat.
Profile
Change of performance over time or distance represented in the
points field.
Programs
Training possibilities requiring manual or program-determined
performances or target pulses.
Percent scale
Comparison display between current power and maximum
power (400/600W).
Points field
Display area with 30 x 16 points for representing performance
profiles as well as text and value displays.
Pulse
Recording of the heartbeat per minute
Recovery
Recovery pulse measurement at the end of training. From start
and end pulse of one minute the deviation and a fitness grade
are determined. For the same training, the improvement of this
grade is a measure for increase in fitness.
Reset
Deletion of display contents and restart of display.
Interface
9-pole SUB-D socket (RS232/serial) for data exchange with a
PC.
Control
The electronic equipment controls the power or the pulse for
manually entered or default values.
Target pulse
Manual or program-determined pulse value, which is to be
achieved.
