Current 
potentiometer 
value 

Two short beeps are heard and the 
calibration is complete.  
The ergometer is ready to use.

Next calibration point

Check the potentio-
meter value at 0 kp.

• 

Reset the scale, see "Scale adjustment”

• 

Release the brake belt tension by lifting the 
pendulum over 4 kp (the engine runs).  
The brake belt tension can also be slack-
ened 
by running the engine manually. This is done 
by pressing (-) in the calibration mode.

Move the pendulum to 
the corresponding value 
and keep it steady until 
the potentiometer value 
stabilized. 

Press ENTER for next 
step. 

Repeat according to the 
pictures to the right. 

Press START STOP 

and

 PROGRAM for 

two seconds to enter 
'Calibration mode'. 

If you have started the calibration mode but  

change your mind, you can press START 

STOP  

to exit without saving

But, if you have pressed ENTER, the calibration rou-
tine has started and must then also be completed. 

Calibration is necessary so that the electronic and the mechanical parts of the ergometer conform. 
Normally, you do not need to re-calibrate the ergometer electronically, but it should occur after each 
service, replacement of the electronics part, movement or if the scale is adjusted. 
New calibration automatically replaces the old one. 

CALIBRATION

All ergometers are calibrated at the factory, but a 
calibration of the pendulum can still be made if necessary. 
Do as follow: 

• 

At first, follow the instructions in section "Scale 
adjustment". Adjust the pendulum if necessary. 

• 

Loosen the calibration hook from the hook holder, 
see 

Fig: Calibration 2.

• 

A checked and approved weight, 4 kg (Art. No: 
9000-211), attached to the calibration hook, see 

Fig: 

Calibration 2.

• 

When properly adjusted, the weight should be read on 
the pendulum scale at the 4 kp line. (The pendulum 
pointer should be in the middle of the 4 kp line.)

• 

Lift off the calibration weight and replace the 
calibration hook in the hook holder, see 

Fig: Normal 

mode. 

NOTE! The hook must be in the holder when 

using the ergometer. 

If the pendulum pointer does not stand in the middle of 
the 4 kp line the pendulum weigh must be adjusted by 
means of the adjusting weight. To be able to do this the 
left cover must be removed.  

To adjust the position of the adjustment weight, the 
locking screw, in the center of the pendulum, must be 
loosened, see 

Fig: Calibration 1.

If the pointer shows too low, the adjustment weight must 
be moved upwards. If the pointer shows too high, the 
adjustment weight must be moved down and then locked 
in its new position. This process is repeated until pointer 
is in the correct position.

Check the calibration of the pendulum once a year or 
when needed.

Error message: CalErr - 
the potentiometer value 
is outside the window. 
Contact your dealer or 
service.  

NOTE!

It does not have to be 
the same values as 
shown here as they 
should only be seen as 
examples.
