2) Number of Pre-flash
For red-eye prevention and auto-flash light adjustment, some devices can pre-flash
before main flash burst.
With the normal setting, the light meter will measure the pre-flash bursts and not the main
flash burst. To take a successful reading, activate the pre-flash feature in the Tool Box.
