Arm Calibration
Important: Always perform the Arm Calibration imme-
diately after Machine Calibration. The balancer software
will not permit it otherwise. During Machine Calibration,
the balancer software calculates both the A (offset) and
W (width) dimensions. The Arm Calibration gives the
balancer software a reference point to the edge of the
faceplate and home position. When the user enters the
A dimension from the arm rod, it calculates the differ-
ence from the Machine Calibration A and uses that as a
factor for the manual A entry. Arm Calibration also gives
the D dimension a reference point from home position.
1. Complete the Machine Calibration procedure (see
page 17).
2. Press and hold the Function key and Calibration
key for three (3) seconds to select the Arm Calibration
mode.
3. Bring the tip edge of the arm precisely to the outer
edge of the faceplate and hold it there while pressing
the Function key. If necessary to reach the faceplate
accurately, loosen the calibration wheel temporarily.
4. With the arm still at the edge of the faceplate,
press A key and use UP / DOWN arrow to adjust A
dimension value as shown on arm gauge. Display will
show at static position of LED. Press Function key.

5. Move the arm to its home position and press the
Function key.
6. Move the arm to the clip-on weight location on the
rim flange and hold it there; press D key and use UP /
DOWN arrows to adjust the D dimension value. Display
will show at static position of LED. Press Function key.
7. While still holding the arm at the clip-on weight
position on the wheel, press A key and use UP / DOWN
arrows to adjust the A dimension value as read off the
arm gauge. Press Function key.
8. Return arm to home position.
9. When machine displays “END”, the Arm Calibration
is complete. Press FUNCTION to exit.
Important: To redo the Arm Calibration procedure,
press and hold FUNCTION and press “Clip 1” for 3
seconds to enter CDE mode, then press “T1 Tape” then
press “W” to bypass the Machine Calibration require-
ment. Always use the same wheel assembly that was
used during the Machine Calibration or else the calibra-
tion will not be correct.
