3.
Press the Rotary Control Dial to set and confirm the desired flash power.
Strobe
In Strobe mode the XMT can rapidly fire a predetermined number of flashes at set time
intervals. This feature can be used to capture multiple images of a single event on one
exposure.
To set up and use Strobe mode:
1.
Press the MODE button on the rear panel until STR is displayed on the LCD screen.
2.
Turn the Rotary Control Dial to adjust the flash power to the desired level.
3.
Press the Rotary Control Dial to set and confirm the desired flash power.
4.
To set the number of flashes and time interval press the Rotary Control Dial.
5.
The time interval value (Hz) will then be highlighted and can be adjusted. Press the
rotary dial to confirm desired time interval value and to select the number of flashes
required.
6.
Turn the Rotary Control Dial to adjust the number of flashes required.
7.
Press the Rotary Control Dial to confirm the number of flashes.
8.
When the unit is fired it will 'strobe' with the set number of flashes at the set time
interval.
Calculating your shutter speed when using Strobe mode - When in Strobe mode, your
cameras shutter will need to remain open long enough to capture all of the flashes. The
formula below will help you calculate the required shutter speed.
Number of flashes / Flash frequency = Shutter speed
Example: number of flashes @ 20 / flash frequency @ 5 (Hz), then the shutter speed = 4
seconds.
Further information:
• In Strobe mode only 1/4 flash power or lower can be selected. Full or 1/2 power cannot be
selected.
• To prevent overheating and component deterioration, do not use Strobe mode
repetitively in excess of 10 times. If Strobe mode is used in excess of 10 bursts the XMT
may automatically disable all flash modes to allow the components to cool down. If all
flash modes are disabled due to excessive Strobe bursts allow at least 15-20 minutes
for the unit to cool sufficiently.
