Optical Pickup (OP) - This function uses an optical pickup that is plugged into the TDC port and it is triggered
from a piece of reflective tape that is mounted on the flywheel.
Like the MP mode, this mode also has a
/ button which toggles
between TDC only mode and TDC & DEG
mode.
Note: Before changing to this mode, the user
must have already set TDC having a stable
RPM.
The TDC & DEG mode also adds the
indicator.
