Calibration

Although all Ergometers are calibrated at the factory

the user may wish to verify this by performing a me-

chanical scale calibration. If so please do the follow-

ing.

Remove the brake belt from the spring. Lean the

bike forward so that the calibration weight, 4kg(4)

(Art. No: 9000-211) is hanging independently from

the frame cover. Be sure that the scale board is set to

zero before the weight is put on, see section ”Scale -

zero adjustment”. Put the weight on on the spring(6).

When correctly set, it should be possible to read this

weight from the corresponding place on the scale

board(7). See ﬁg: Calibration.

Should there be a deviation, adjust the pendulum to

the correct weight on the scale by means of the ad-

justing weight inside the pendulum(3). See ﬁg: Scale

adjustment. To change the position of the adjusting

weight, loosen the lock screw(8) on the back of the

pendulum weight. Should the index of the pendulum

weight be too low, move the adjusting weight upwards

in the weight and if the index should be too high the

adjusting weight is moved somewhat downwards and

locked in the new position. Repeat until the correct

reading is achieved.

Check the calibration of the pendulum weight once a

year or when needed.

Scale - zero adjustment

Loosen tension device so that the brake belt feels

loose. 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 board.

Tighten the lock-nut after the adjustment. See ﬁg:

Scale adjustments.

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 lockscrew for scale

indicator(9). Tighten the screw ﬁrmly after the adjust-

ment. See ﬁg: Calibration, Adjustment kp-scale win-

dow.
