6.3 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
F
(C4
7.1.1) 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, "P"
MODELS ONLY :
THE CLAMPING TOOL SUPPLIED WITH THE
MACHINE SHOULD BE LOCKED ON THE SHAFT
(Figure 6-2).
Readjustment
• Select the "*" key and the "precision" key together
for 5 seconds.
• The display shows "C 14".
• Select the "Enter" key (0, Fig. 6-3).
• The display shows "CAL 1" (1, Figure 6-3) and the
unit beeps.
• Spin the wheel.
• When done, the display shows "CAL 2" (2, Figure
6-3).
• Mount the User Calibration Weight, refer to Figure
6-2.
• Spin the wheel.
• The wheel will be braked. After a few seconds the
display equals Figure 6-3 (3).
The UC was performed correctly.
-
Any (operator) error causes the program
F
to exit (
7.1.2).
— Unscrew the Calibration weight from the fl ange and
put it back in its designated place in the Weight
Holder Tray.
• Press STOP to exit.
