Baseline 225 Manual - Calibration Program

Calibration program
First sensitivity calibration
This program needs to be run whenever the settings appear to be out of tolerance or when the
machine requests self-calibration spontaneously by displaying the message “Er1 CAL”.
Select a wheel of average size and weight,(preferably with a limited unbalance, and fit to
the shaft.
Enter the correct geometrical data for the wheel.
Press the keys until the CAL program indicator lights up.
Press
to confirm selection of the program.
The machine is now ready to carry out first sensitivity calibration and will display the message
“CA.1”.
Rotate the wheel to the point denoted by the position indicator and by the appearance of the
valve”100”(or 3.5 if ounce mode is selected) in the display.
Attach a 100g (or 3.5oz) sample weight to the outside of the wheel rim. Positioning at 12
o‟clock exactly.
Make a first spin.
Once the wheel is at standstill, remove the sample weight from the outside plane and rotate the
wheel to the point denoted by the position indicator and by the appearance of the value
“100”(or 3.5) in the display.
Attach the 100g (or 3.5oz) sample weight once again to the OUTSIDE of the wheel rim, at 12
o‟clock exactly.
Make a second spin.
If the calibration program has been completed successfully, this will be confirmed by a beep
following the spin. If not, the message “Er3 CAL” is displayed.
The self-calibration program ends with the display showing the unbalance values for the wheel
(ignoring the sample weight).
Notes
Remember to remove the 100g (3.5oz) sample weight at the end of the procedure.
The key can be pressed at any given moment to abort the calibration procedure and return to
the program selected previously.
The calibration described above is valid for any type of wheel.
Second sensitivity calibration
This program is used to self-calibrate the machine to make it extremely accurate even with very high
unbalance values (over 200g of static unbalance with average size wheels). It should be done when
the machine itself calls for by displaying the message “Er2 CAL”.
