P/N 5900262 — Rev. A1 — Jan. 2021
Calibration
Calibrate the Balancer on a regular basis using the 100 g weights included with the MB-240X.
IMPORTANT: When placing the calibration weights on Wheels, apply weights exactly perpendicular to
the shaft at the 12 o’clock position. Incorrect placement will result in additional weight
call outs and/or an improperly calibrated machine.
To Calibrate the Balancer:
Install a known good Wheel on the Balancer.
Enter the Wheel Inside Distance, Width and Diameter.
Press and hold the R and F keys at the same time. Both Inner and Outer Display windows should
display CAL and the Wheel position indicators should be flashing. Hold the keys down until the
Wheel position indicators stop flashing (about 5 seconds) then release.
While facing the Wheel, start spinning the Wheel in a clockwise  direction. Begin by pushing with
your hand against the Tire, then turn the Quick Nut black handles to increase the speed of rotation
until the Outer Display Window reads
run .
Release the Quick Nut handles and wait. After a few seconds, the inner and outer display should
read:
Pull the brake handle against the Tire to stop the rotation.
Slowly turn the Wheel until all the inner weight position indicators are lit. Use the brake to hold the
Wheel in place.
Clamp a 100 g calibration weight to the top dead center position on the inner edge of the Tire.
