NOTE
● In the HSS Cordless Flash Mode, the backlight of the LCD screen dims and is only
illuminated for three seconds after measurement.
● After the measurement, the meter enters the 90-second Standby Mode again. If you
need to measure again, fire the flash during this time.
● I f the measured values are stored in the memory, the Measurement Standby Mode is canceled.
● If the icon stops blinking before the flash fires, repeat Steps 6 and 7.
● To stop the Standby Mode, just touch the screen.
● It is convenient to set the light meter in a fixed position during the measuring time. This
can be accomplished by mounting the meter on a tripod or stand using the tripod socket
on the bottom of the meter.
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.
