'Wfm does not cross ref' message

On many of the TDS scopes the message ' Wfm does not cross ref' appears for C1, C2, or both. These scopes may or may not pass some or all of the start up and calibrations tests. I cannot find the meaning or significance of this message in the service manuals. Can anyone explain the meaning of this screen message? Thanks!

I suppose that Wfm this is the sort version of the word : Waveform.

Therefore the message could be that : Waveform this does not cross reference points ... possibly because signal amplitude this is not enough or higher than what it is required for calibration.
