Electronic calibration
When calibrating the electronics do the following:
Turn off the power by pressing the power 1.
switch (2) which is placed on the frame, see
Fig: Connections. in section ”Connection to an
external unit”.
Adjust the scale mechanically so that 0-index on 2.
the scale and indicator are in line.
Move the indicator to 4 kp and hold it there.3.
Turn on the power again. (The green LED on the 4.
lower left side of the bike is lit up when there is
power to the bike.)
Hold the indicator at 4 kp until one beep is 5.
heard.
Move the indicator to 0 kp and wait for one 6.
beep.
Move the indicator to 2 kp and wait for one 7.
beep.
Move the indicator to 4 kp and wait for one 8.
beep.
Move the indicator to 6 kp and wait for two 9.
beeps.
Move the indicator to 0 again. 10.
Calibration is done.
The indicator can now be used to set the bike in
different modes.
Mechanical calibration
Although all Ergometers are calibrated at the factory
the user may wish to verify this by performing a
mechanical scale calibration. If so, please do the
following.
Loosen possible tension in the brake. See ”Scale - zero
adjustment”. Check that scale 0-index is in line with
the pointer(1). See Fig: Calibration. If adjustment is
needed adjust according to ”Scale -zero adjustment”.
A checked and approved weight(4), 4 kg (Art. No:
9000-211), is attached at(5). See Fig: Calibration.
At the correct calibration, the indicator should point
to 4 kp on the scale.
If there is a deviation adjust the pointer to the
correct position by adjusting the weight inside the
pendulum(2). To do this the left cover has to be
removed.
To adjust the position of the weight, the locking screw,
in the center of the pendulum(3), must be loosened.
If the pointer shows too low, the internal weight must
be moved upwards. If the pointer shows too high, the
adjustment weight is moved down. This process is
repeated until pointer is in the correct position.
Check the scale calibration once a year or if required
due to service.
