6.3 Calibration procedure.
This chapter contains the calibration procedures that
are accessible to the user.
Note: No tire or wheel is required to perform
this operation.
6.3.1 User calibration.
Use this function if the quality of the balancing process
is not optimal. This happens when wheels are balanced
properly on the unit, but still feel off balance when
driving.
•
Switch off the machine.
•
Turn on the machine while pressing and holding
down button “
CAL ” until the display blinks “CAL
USR” followed by “dis NNN”.
Do not enter any tyre data.
•
Press “ F ” button. Display on the right will show 1.
•
Lower the hood to cycle the balancer shaft with
nothing on it. After the measuring run the display
will show 2.
•
Mount the calibration weight into the treaded hole
on the left side of the balancers flange (Figure
6.3.1.1).
•
Perform a spin.
After a delay of two seconds “DNE” appears (Figure
6.3.1.2) if calibration was successful, or an error
message appears if it failed. See Chapter 7.1 for error
messages.
6.3.2 Adapter Imbalance Compensation
This section indicates how to compensate for
imbalances
caused by weights added to the wheel shaft, before
fitting the wheel.
The machine can perform an automatic calibration operation
to allow automatic electronic compensation for any
mbalances caused by optional adapters installed by the
user, for example flanges and equipment for locking the
wheel in general. This technology guarantees balancing
precision equal to that done with the wheel directly mounted
on the machine shaft.Compensation can be deselected at
any time.
In any case, the machine returns to the manufacturer’s
calibration condition each time you start it up.
- Operation
Fit the required adapter on the wheel shaft.
•
Simultaneously press keys F – FINE , the display shows
“SEL ECt”. Hold down the keys until “BAL Sht” appears and
an acoustic signal is activated.
•
Press F . “BAL 0” appears on the display.
•
Press one of the three + keys to display “BAL 1”.
•
Lower the guard and start the operation. Wait until it
stops to ensure that the operation is completed.
The machine now allows wheels to be balanced using
normal procedures.
To cancel the compensation obtained:
•
Return to the “BAL 1” display using the above-mentioned
procedure.
•
Press any of the three – keys to display “BAL 0” again.
•
Press the STOP key twice.
