Machine Calibration
1.
Press SETTINGS icon and then select MACHINE
CALIBRATION.
2.
Press continue.
3.
Enter the D dimension (include decimal point,
example: 16.0 for a 16-inch wheel). Press ENTER.
4.
Lower the hood and press SPIN.
5.
After spin, raise the hood. Attach 4-ounce calibra-
tion weight to the outside flange at top-dead-center.

Center
6.
Lower the hood and press SPIN
Important: It is critical that the inner weight be placed
accurately to achieve proper calibration. If the calibration
weight is not moved from the outside flange directly
across to the inside flange, an inner weight placement
error will occur. To correct, follow the balancer instruc-
tions.
7.
After spin, raise the hood. Move the 4-ounce cali-
bration weight directly across and attach it on the inside
flange at top-dead-center.

With arm still at the edge of the faceplate, enter
the A dimension (include decimal point) read off the arm
gauge; see figure 3. Press ENTER.

13.
Move arm to its home position and press NEXT.
14.
Move arm to clip-on weight location on rim
flange and hold it there (through step 16). Wait for volt-
age reading to stabilize, then press NEXT.
15.
With arm still at clip-on weight location, enter
the D dimension (16.0 for a 16-inch wheel) that is the
diameter of the tire. Press EXIT.
16.
While still holding the arm at the wheel’s clip-on
weight location, enter the A dimension (include decimal
point) read off the arm gauge. Press ENTER
17.
Return the arm to home position; calibration is
complete. Press EXIT. Press STOP & EXIT to go back to
