PX-712UF Installation and Users Manual
Measuring Tracking and Focus Error
Supported in PlexTools Professional software, this function reports on
the mechanical characteristics of the DVD or CD you’re using in the
Plextor PX-712UF drive. It actually measures the amplitude of the laser
focus error and tracking error, and displays the results. (This function
tests blank CDs and DVDs.)
To use PlexTools Professional to measure tracking and focus error:
1. Place a blank DVD+R/RW, a DVD-R/RW, or a CD-R or CD-RW
disc in the PX-712UF. (Don’t use a pre-recorded, commercially
stamped disc.)
2. From the PlexTools menu bar, select Q-Check FE/TE Test. You see
the Q-Check window with a graph for focus error and tracking error.
