to confi rm.
to cancel the width gauge calibration function if it
has erroneously been accessed.
6.4.2 Balancing machine calibration
To calibrate the balancing machine, use a wheel with steel
rim of average dimensions, e.g. 6” x 14” (±1”).
To properly perform the procedure:
Mount a wheel on the machine, even unbalanced, and ▪
very carefully set its dimensions.
INDICATION
Setting incorrect measurements will result in the machine
not being correctly calibrated, and balancing of subse-
quent wheels will hence be incorrect until the machine is
recalibrated with the correct measurements!!
Follow the on-screen instructions. ▪
INDICATION
To enable saving of the weight statistics
( WEIGHT STATISTICS)
The weights are saved only if the unbalance display pitch
is set to 5 in 5.
6.4 CALIBRATIONS
When 4 is pressed from the Special Functions
menu, access is gained to the Calibration menu.
6.4.1 Gauge calibration
6.4.1.1 Distance gauge calibration
To calibrate the distance gauge, set it in rest position and
then on the adapter plane.
When done, set the gauge in rest position. If calibration is
correct, the wheel balancer is ready for operation, otherwise
an error message may be displayed if there are errors or
malfunctioning; in this case repeat calibration.
to cancel the distance gauge calibration
function if has erroneously been accessed.
6.4.1.2 Diameter gauge calibration
To calibrate the diameter gauge, place it on the adapter
fl ange and press . For better calibration turn the gauge
downward and position it 40 mm away from the adapter plane.
On the screen a value is shown near the word POS: if it is
256+/- 3°, set the gauge to rest position, otherwise press
.
to cancel the diameter gauge calibration function if
it has erroneously been accessed.
6.4.1.3 Width gauge calibration
When calibrating the width gauge, set a measurable di-
mension as follows:
