Scale - zero adjustment
Connect power to the bike. Loosen possible tension
in the brake belt by moving the indicator to 0.5 kp.
Hold it there until the belt feels loose. Then move the
indicator to 0 again. Now check if the indicator is
aligned with the 0-index on the scale.
If adjustment is needed, loosen the locknut(1) and
then change the position of the scale board, so that it
will have its 0-index in line with the pointer. Tighten
the lock nut after the adjustment. See
Fig: Scale

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:
First, follow the steps in the "Scale - zero •
adjustment”. Adjust the pendulum if necessary.
Loosen the calibration hook from the hook •
bracket, see Fig: Calibration mode .
A checked and approved weight(4), 4 kg (Art. No: •
9000-211), attached to the calibration hook (5),
see
Fig: Calibration . Note! The calibration hook
should always be left in the hook control.
If the calibration is correct, the indicator should •
point to 4 kp on the scale.
Lift off the weight and replace the calibration •
hook in the hook bracket, see Fig: Normal mode .
Note! The hook must be inserted in the holder
during operation.
If there is a deviation, adjust the pendulum to the right
position on the scale by adjusting the weight inside
the pendulum (2). To do this the left cover must 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 calibration of the pendulum weight once a
year or when needed.
