Calibration

Although all Ergometers are calibrated at the fac-

tory the user may wish to verify this by perfor-

ming a mechanical scale calibration. If so please

do the following.

Remove the brake belt from the spring. Lean

the bike forward so that the calibration weight,

4kg(4) (our part no: 9000-211) is hanging inde-

pendently 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

adjusting weight inside the pendelum(3). See ﬁg:

Scale adjustment. To change the position of the

adjusting weight, loosen the lock screw(8) on the

back of the pendelum 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 ver-

tical 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 lock nut(1) and then change the posi-

tion 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 lossen the lock

screw for scale indicator(9). Tighten the screw

ﬁrmly after the adjustment. See ﬁg: Calibration,

Adjustment kp-scale window.
