Scale - zero adjustment
Check that the pendulum will hang in vertical position.
Scale board:
Check that the index on the pendulum (2) weigh is
aligned with the index at the 0-position on the scale
board. If adjustment is necessary, first loosen the
locknut (1) and then change the position of the scale
board. Tighten the locknut after the adjustment. See
Fig: Zero adjustment.
Kp-scale:
At the same time, check that the kilopond-scale
(5) to the left of the meter, shows 0 in line with the
index. To adjust the kp-scale loosen the lock screw
for scale indicator (9). Tighten the screw firmly after
the adjustment. See Fig: Calibration and Adjustment
kp-scale window
Calibration
All ergometers are carefully calibrated at the factory.
You can check the calibration if you want to verify
this, if so, proceed as follows:
Be sure that the scale board is set to zero before the
weight is put on, see section ”Scale - zero adjustment”.
Remove the brake belt from the spring. Thread the
calibration weight string from below, inside the frame
cover, so the string is between the flywheel and the
frame cover. Hook the string into the spring (6). If the
calibration is correct, it is possible to read this weight
from the corresponding place on the scale board (7).
See Fig: Calibration.
If there is a deviation, adjust the pendulum to the
right position on the scale by adjusting the weight
inside the pendulum (3). See Fig: Zero adjustment. To
change the position of the adjusting weight, loosen the
lock screw (8) on the back of the pendulum weight. 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.
