Monitor Auto Cal values by doing a right click and select 'monitor' on highlighted bit once calibration is complete.
|

|
Compare new and old Calibration Values.
|
Compare new calibration values after calibration with older values saved before calibration.
If difference between old and new calibration value for each lane is not more than +-1, save the new values if not then do not save new values and check the devices on the lane showing difference.
Example of new cal values are shown here.
