Single Bar Calibration

9. Mount the front selected wheel clamps and target assembly to the calibration paddles.

NOTE: The wheel clamp and tar-
get assembly must be mounted
vertical before continuing. This
initial reading is recording the
RTp data and marks vertical for
all alignments.

10. Press the “Next” icon to con-

tinue.

8. Place the calibration bar and stands

in front of the turnplates

if possible and mount the paddle assembly

to the bar.
