Calibration
Calibration is done at the factory. If you for some rea-
son want to check the calibration, do as follows:
Tighten the brake belt through turning the control
knob so that pointer goes up to about 25-50 Watt at
rotation of the crank. Put the Rehab Trainer at the
edge of a table. Loosen the screws for the clamping
plate(3), so that the end of the belt is loose. See fig:
Calibration. Fasten a 2 kg weight (Art. No: 9000-
212) to the brake belt(2). This weight should now be
read on the scale at 2 kp. See fig: Watt scale.
Should there be a deviation between the position of
the pointer and the 2 kp marked on the scale, adjust
the loading spring by turning the adjusting screw un-
til the correct position is obtained. See fig: Calibra-
tion and fig: Watt scale. Turn clockwise if the pointer
is placed too high and turn counter clockwise if the
pointer is placed too low. Remove the weight and fas-
ten the brake belt with the screw for the clamping
plate so that the pointer does not go below the zero
(“0”) marked on the scale.
The height level of the cranks is adjustable when loos-
en the nuts, see fig: Adjustments. Set the crank arms
at the desired position and fasten with the nuts. If the
cranks are not in line, adjust these. First set the left
hand crank straight upwards. Then loosen the right
hand crank by undoing the crank arm screw(6). Ad-
just the position of the right hand crank so it is in line
with left hand crank and tighten the screw.
