User Calibration

If several measuring runs are necessary to balance
a wheel because balance weight size and position
have to be adjusted repeatedly, this is often due to
insuffi cient measurement accuracy.
If this is the case the operator can electronically
calibrate the rotating masses on the machine; which
is called User Calibration.
A calibration run takes longer than a regular measuring
run.
Following User Calibration any residual compensation
will be cancelled.
Important:
User Calibration should only be performed
with nothing on the shaft; and with no external
tools whatsoever on the wheel holder.
FOR MACHINES WITH A POWER CLAMP ONLY:
On "p" models, only the
clamping device supplied with the machine (Figure
6-6) must be blocked.
Calibration
— Make sure that no clamping tool (and no wheel or
other device) is mounted on the machine shaft.
— From MAIN MENU (Fig. 6-1) press key 3 three
times in succession and select
C 14 CALIBRATION (Fig. 6-4).
The CALIBRATION 1 screen (Figure 6-5) will open.
— Close the wheel guard, press the START key and
launch the fi rst calibration run (if the run takes a
long time it means residual imbalances have been
detected).
The CALIBRATION 2 screen will open.
— Screw the Calibration weight W (Fig. 6-6) onto the
threaded hole in the wheel support fl ange.
— Press the START key and launch a second
calibration run (to detect correction values).
After the second run the electronic control unit
processes the values taken during the calibration runs
and writes them in the permanent memory. When
this has fi nished an audible 3-tone signal is heard to
indicate that User Calibration has terminated.
— Unscrew the Calibration weight W from the fl ange
body and put it back in its designated place in the
Weight Holder Tray.
— Press the ESC key to return to the INTRODUCTION.
