9.4.2 Manual mode Qflash Compensation 
This procedure will calibrate Qflash to an incident light flash meter you 
use and trust. Note that only incident light measurements are reliable for 
manual exposure settings. 
1. Place the Qflash Trio 
10 feet from the incident flash 
meter that is facing Qflash. 
2. The area surrounding the 
meter and flash should be 
similar to the shooting environment 
you usually work in. For example, 
in a large hall, there will be little light bouncing from walls and ceilings.  
In a small room, the light meter reading will be increased by whatever 
bounce occurs from nearby surfaces. These factors will affect calibration 
and should be considered. 
3. Turn the Trio on, set mode to manual (M) and change the manual 
power setting to 1/8. 
4. Set the film speed (iso) on the Qflash and the flash meter to the same 
value. 
5.Change the F number on the flash until the distance shown in the 
display is 10 feet. 
6. Fire the Trio. Note the F/number on the flash meter. 
7. Press the MAN soft key, 
then use the UP and  DOWN 
soft keys, adjust the F/ number 
in the display until it matches 
the F/ number from the flash 
meter.
