5.5 Calibration
This chapter describes the calibrations that can be
performed by the operator.
5.5.1

User calibration

If a number of different measuring runs have to be
performed to balance a wheel and the values and
positions of the weights have to be changed, it generally
means that measuring is not precise.
In this case the operator can recalibrate the machine.
To perform a so-called "User Calibration", the operator
should use the calibration weight supplied with the
machine (located at the back of the machine).
A calibration run usually lasts longer than a measuring
run.
Clamping element imbalance compensation is deleted
following a User Calibration.
Note:
Before performing a User Calibration ensure the
clamping device supplied by the manufacturer is fitted.
Calibration (Cod. C14)
• Make sure that only the clamping device is fitted to
the main shaft (no wheel or any other clamping
accessories).
• Press F then C-Code.
The base value C - - is displayed.
• Use the + and - keys to select the C14 Code.
• Press the C-Code key.
Value "I" is displayed.
• Perform the first calibration run (a longer measuring
run to detect any residual imbalances).
At the end of the first calibration run value "2" is
displayed.
• Screw the calibration weight into the bore on the
clamping device (Figure 5.5.1-1).
• Press the START key to perform the second
calibration run (with the calibration weight to detect
the adjustment values).
After the second measuring run, the electronic system
processes the values registered in the calibration runs
and saves them in the permanent memory. At the end
of the processing phase the machine sounds a three
tone beep (Tu Du Lu) to indicate that recalibration is
complete.
The base indication C - - appears.
• Press the STOP key.
The base operating picture appears.
• At the end of the calibration procedure unscrew the
calibration weight from the clamping device and put
it back in its place.
You can now proceed with normal balancing operations.
