High Speed Synchronization - Cactus V6 IIs User Manual

Note: The absolute power set up will not be saved upon switching off the V6 IIs TX.
The V6 IIs TX will restart in relative power mode.
12.3 EV Step
The control panel of the V6 IIs TX offers three EV step options: 1/10 EV, 1/3 EV, and
1/2 EV. The configuration applies to both relative and absolute power modes.
To adjust the EV step, switch on the V6 IIs in TX mode and press
selection dial to <EV STEP>. Press
level (1/10, 1/3, or 1/2). Press
Notes:
1. The selected EV step will be memorized upon switching off and will be applied
when switching on again.
2. In the quick power adjustment mode (see Section 12.1.3), the configured EV step
will be replaced by the 1EV step changes.
12.4 Lo Power
At the Lo Power level, the relative power output of a flash triggered by the V6 IIs is
roughly equal to 1/256. The difference between 1/128 and 1/256 power outputs may
be hardly detected by flash meter, but the extremely short firing duration helps
freeze faster-than-lightning moments and is ideal for high-speed photography.
To enable Lo Power:
1. Switch on the V6 IIs in TX mode and press
POWER> and press
2. Once the Lo Power is enabled, the Lo Power will be shown as <Lo> at one step
below 1/128 power in the relative power mode, or one step below the lowest
power of each group in the absolute power mode.
3. To disable the Lo Power output, follow step 1 to enter the Lo Power menu. Turn
the selection dial to <OFF> and press
