8.2.2 Shaft calibration
Remove all accessories from the shaft. Fulfill several measurements of imbalance.
Being in «New wheel» state press the button
MENU
. Choose «Shaft calibration»
state. Then after the request on the display lower the cover for the imbalance measurement.
After the message about shaft calibration completion press the button
EXIT
. After that
fulfill the shaft calibration.
Irrespective of current wheel type, shaft calibration will be made for both types of a wheel: motor-car
and truck- car.
8.3 Gauge arms: testing and calibration
The imbalance calculation accuracy substantially depends on the geometric parameters
measurement accuracy. Inaccurate readings of the gauge arm may lead to the increase of
measurement cycle number during one wheel balancing. Although the gauge arm accuracy
doesn't influence balancing quality (i.e. residual wheel imbalance).
8.3.1 Gauge arm diagnostics
Gauge arm diagnostics should be done during machine operation. The diameter shown
during wheels measuring must correspond to tyre marking. In case of any mismatch it is
recommended to fulfil gauge arm calibration.
8.3.2 Gauge calibration
Put the gauge calibre on the shaft as it’s shown in Figure 8.2a.
Being in «New wheel» state press the button
MENU
, choose «Gauge calibration»
option
By the program request «Move the gauge arm tip to point 1» move the tip of the gauge
arm upward and insert into opening "1" of the calibre as shown in Figure 8.2a. Press
OK
.
By the program request «Move the gauge arm tip to point 2» move the tip of the gauge
arm upward and insert into opening "2" of the calibre as shown in Figure 8.2b. Press
OK
.
To cancel calibration press
ESC

If the calibre is last you can use a usual ruler. Set a butt of the ruler against shaft body.
Move the upper edge of the tip up to mark 133 mm instead point 1. Instead point 2 - up to mark
223 mm.
