Measuring Q-Check PI/PO Errors
This function reports on the PI (parity inner) and POF (parity outer fails)
on the current DVD disc in the Plextor PX-712 drive. This test is for use
on a DVD that contains content—that is, a commercial pressed DVD or
a disc recorded on a DVD burner.
To measure PI/PO error:
1. Place a pressed DVD disc, or a recorded DVD+R, DVD+RW,
DVD-R, or DVD-RW disc, in the PX-712.
2. From the PlexTools menu bar, select Q-Check PI/PO Test. You see
the Q-Check window with a graph for PI and POF errors.

check.
