5-3. Measuring with Radio-controlled Flash (for L-478DR only)
5-3-1. How to Measure Using Radio Control
Triggering ashes by radio requires connecting a PocketWizard
®
radio receiver (sold
separately) to the ash unit to receive the trigger signal transmitted by the meter. Radio
triggering enables a single photographer to easily trigger and measure ash.
The followings are the modes that can be set to measure this way.
•
Radio Triggering Flash Mode
•
Radio Triggering Multiple (Cumulative) Flash Mode
* The radio transmitter built into the L-478DR is compatible with PocketWizard brand radio
products as well as ash brands that have PocketWizard
®
radio receivers built into them.
Please read the instruction manuals provided with these products for details about using
them.
Please go to www.pocketwizard.com to learn more about radio triggering compatibility.

Successful radio triggering depends on several factors. Please read these setup steps before using the L-478DR to radio
trigger ash units.
1. It is best to position the meter in sight of the radio receiver.
2. Position the radio receiver so that it is away from large metallic objects, concrete, or containers of water (like people).
3. Secure the radio receiver to the ash using hook-and-loop-type attachment tape or the threaded socket on the radio.
Make sure the radio’s antenna is above the ash body or generator pack. Do not allow the receiver antenna to contact
metal objects.
4. Sometimes, conditions will not allow radio reception. ese could include strong local radio interference, or being near
objects that blocking or absorb the signal. Repositioning the radio, even slightly, can reestablish contact. Alternatively,
check to see if the radio receiver is behind an object that absorbs or blocks radio waves, such as concrete, metal or low
hill.
5. Operation is best when the meter to receiver distance is within 30 meters.
5-3-2. How to Measure with Radio Control Channels
1) Radio System
The L-478DR can transmit both Standard and ControlTL
®
radio signals.
<ControlTL
®
Channel>
When used with ControlTL
®
receivers, the L-478DR is capable of controlling
the power level of the compatible ashes connected.
The ControlTL
®
system features 20 channels for FCC&IC version or 3
channels for CE version, and three zones (A, B, C) allowing control of three
separate ashes on each channel.
<Standard Channel>
PocketWizard
®
Standard radios provide simple triggering and do not allow
power control. The feature 32 channels: Channels 1-16 re single trigger
signals; Channels 17-32 have four zones (A, B, C, D) which enable triggering
four separate ashes on each channel.
