External synchronous emission 4.4
External synchronous emission is the function to emit a strobe flash in synchronization with an
external pulse.
•To activate external synchronous emission mode, refer to 4.2 Emission setting.
• You can set which edge of the external pulse triggers the emission, the rising edge or falling edge.
Refer to 4.6.3 Trigger edge setting.
•Timing (delay) from the external pulse entry to strobe flash emission can be optionally set.
Emission count mode 4.4.1
Measurement value of the emission count (frequency)
Indicates the external
synchronous emission
Mode display
Indicates the memory
number
* The external pulse frequency is measured per cycle and indicated (An averaging procedure is applied
every 200 ms to update the measurement value and indicate the latest one.)
If the external pulse cycle is beyond the specifications range, the following letters are indicated.
[Without the delay angle setting]
Measurable range 40 to 35,000
When the external input pulse
frequency goes below 40 fpm
When the external input pulse
frequency goes beyond 35,000 fpm
[With the delay angle setting]
Measurable range 60 to 10,000
When the external input pulse
frequency goes below 60 fpm
When the external input pulse
frequency goes beyond 10,000 fpm
