Calibration
With the tow vehicle on a level surface and no brakes applied, press and hold the load
range / calibration button located next to the digital display. When a steady 'CL' appears,
calibration is complete. Recalibrate if the module loses power, if the mounting angle
changes, or if the 'CL' ashes at any time. NOTE: To prevent inadvertent calibration, the
calibration mode is locked out when the brakes are engaged.
Once properly connected, the display will show one of the following:
