Self-Calibration; Measuring Unbalance - Zipper Maschinen ZI-RWM99 Manual De Instrucciones

17.3 Self-Calibration

Entering the wrong dimensions will cause the machine to be incorrectly calibrated and
all subsequent measurements to be incorrect until a new self-calibration with the
correct dimensions is performed.
To self-calibrate the machine, proceed as follows:
1. Mount any wheel on the shaft, even if it is not balanced; better still, if it has an average
size.
2. Set the exact dimensions of the wheel (a, b, d value).
The value measured by the machine during the self-calibration cycle is automatically kepted in
a special memory, which stores it even when the machine is switched off. This means that the
machine is immediately ready for operation after being switched on again. Self-calibration
should be carried out from time to time or if there are doubts about the correctness of the
measured results.

17.4 Measuring unbalance

To perform an unbalance measurement, close the protective cover. Depending on the setting,
also press the S
The wheel is brought up to speed within a few seconds, decelerated again and the unbalance
values are displayed on the control panel.
Note: Lightly pressing Button C in the 12 o'clock position displays the preset dimensions one
after the other.
To measure again, close the hood after attaching the weights and press the S

3 Press the F and C button on the control panel
simultaneously until the display shows C
and the LEDs stop flashing.
4 Close the hood and press the S
complete turn is performed and the display shows
Add 100.
5 Attach a 100 gram reference weight to any position
on the outside of the rim.
6 Press S again.

7. After a second cycle, the display shows E
Now the calibration procedure is complete.
8. Remove the reference weight and balance the wheel
as descripted in the following section.
Slowly turn the wheel counterclockwise until all LED's of
the digital display for the internal unbalance value light
up. The correct position for attaching the weight is then
exactly in the 12 o'clock position on the inside of the rim.
Then slowly turn the wheel clockwise until all the LED's on
the digital display for the external unbalance value light
up. The correct position for attaching the weight is then
exactly in 12 o'clock position on the outside of the rim.
