Specifications

PowerTracking with an AC3 ZoneController: When using an AC3 in A (Auto Mode), ash output power on your
remote ash will automatically track up and down with aperture, ISO, or FEC changes on your camera as well as the
Power Dial on the AC3. For example: If you narrow your aperture by 1 stop, ash power will increase by 1 stop to
keep the exposure the same.
Zero (0) on the AC3 Power Dial is centered on the aperture and ISO used for your rst picture. For example, if your
rst picture is at ISO 200 and F:8, then those values will be used as the center point for PowerTracking which is 3
stops down from your ash’s maximum output power.
Follow these steps to set the aperture and ISO values that will be used as the center point:
1. Turn on your camera and MiniTT1 or FlexTT5, but wait to press your shutter button or take any pictures.
2. Set the aperture and ISO you wish to use at the center point. Set the shutter speed as desired, however
changes to shutter speed will not affect PowerTracking.
3. Press the shutter button to take a picture. The center point is now set.
4. Adjust your camera’s ISO, aperture, or FEC to control ash output from the camera automatically
via PowerTracking.
To change the values used for the center point, turn off your transmitter then turn it back on and follow these
steps again.
Set the AC3 zone to Manual Mode to turn off PowerTracking.
Center on ISO & Aperture with First Shot is the default operation. For more information, see the PocketWizard Utility
section on adjusting this setting via the PowerTracking Tab for your transmitter.
IMPORTANT NOTE: Shooting in Shutter Priority/Tv, Program, Full Auto, or shooting quickly or making rapid exposure
changes is not recommended. The ash values may change rapidly and your remote ash may not be able to keep
up. Honor your ash’s ready wait time or “dump” as necessary.
