CALIBRATION OF PENDULUM SCALE

1. Loosen the tension device so the brake belt feels loose.

2. Check 0-adjustment.

See ZERO ADJUSTMENT page 15.

3. Detatch the front screw in the frame covers.

4. Fasten a known weight, e.g. 4 kg (our ref No. 9000-211) at the

balancing spring. Note: The weight should not be less than 3 kg,

due to the possibility of inferior accuracy. Take the left cover a little

to the side so the weight cord hangs between the covers. See fig.

5. When correctly set, it should be possible to read this weight from

the corresponding place on the meter board. See fig 10.

6. Should there be a deviation, adjust the pendulum to the correct

weight on the scale by means of the adjusting weight inside the

pendelum. See fig 9.

To change the position of the adjusting weight, loosen the lock

screw of the 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.
