Notes on Flash Measurement Mode Use
1.
The Aperture (F) displayed, whether the measurement was taken with s synch cord or not, will
display the combined value of the flash and the surrounding Ambient light.【※except FD Mode】
2.
Once the ISO is set, the calculation of the Aperture (F) and the Flash Ratio (FR) are automatically
performed when a reading is taken. 【※except FD Mode】
3.
The set Shutter Speed (T) needs to be within the flah synch speed parameters of the camera used.
4.
The flash may fire if it is turned on when the synch cord is connected to the meter's Synch Port⓯.
5.
If the contracts of the synch cord form an imcomplete circuit, causing the flash to misfire, the meter
will display the "Waiting" message. Press the Measuring Button⓫ to clear the screen, and then
check the synch cord connections before trying another reading.
6.
Measuring under rapid-start fluorescent lights or other special lighting may lead to false readings.
In such case, it's best to take readings using a synch code.
7.
There may be rare instances where the screen freezes and can't be reactivated by pressing buttons.
If that happens, remove the batteries for 15 seconds, replace them, and turn the meter back on.
8.
When metering in a bright location, the meter may not be able to detect a small amount of flash.
In such cases, it may be preferable to measure the flash by connecting a synch cord.
9.
If a flash has an extremely low synch voltage, it may not be fired by a connected synch cord. In
such cases, it may be preferable to meter withoug a synch cord.
