The Cycle Log from a TrueView 3DIS containing a Riegl laser scanner contains a diagnostic message (DIAG), “RIEGL system message: WARNG:OPTIME_FILE_IS_READ_FROM_BACKUP”.
This is a warning message from the Riegl laser scanner that can result if the scanner was not shut down properly during the previous run. This can happen if the TrueView encountered a hard fault or the winddown was interrupted. This warning is benign.
