4.3.3 Emission duration mode
The emission duration (ratio) can be set by 0.1º within the range between 0.1º/ 360º and 3.6º/ 360º in the
emission duration mode (DUR).
(The emission duration setting value shows the strobe emitting time by angle while a rotating object
rotates one revolution (360º).)
A longer emission duration increases the brightness, but a measured object appears to be moving.
Also, a shorter duration time decreases the brightness, but a measured object appears to stand more still.
Adjust the appropriate emission duration according to your application and conditions and use the unit.
Press the "MODE" key to switch to the phase mode (PHA).

4.3.4 Phase mode
When the rotation (motion) cycle of a measured object matches with the strobe flash cycle, the measured
object appears to stand still. To change the angle (position) to make the object stand still, use the phase mode.
The phase can be changed by 0.1º using the dial within the range between 1º and 359º in the phase mode
(PHA).
Press the "MODE" key to switch to the emission count mode (FPM) of external synchronous emission.
