Internal Mode
•Phase Shift will indicate degrees of phase shift in internal flash-
ing mode. To change the degrees of phase shift, press + or -
keys. The display will reflect the cumulative angle of phase shift.
•The flash duration time will be displayed when the RATIO key
is pressed. The flash duration time can then be increased or
decreased with the dial from 0 to 2.5 (0~2.5°) degrees.
External Mode
• In external trigger mode, the display will show the settings of
delay time. For details about changing these settings, please
see external trigger mode section.
Battery Indication
- Indicates remaining battery charge.
Note: The display will not indicate a battery charge when the unit
is being used with the AC Adapter.
Remarks: It can be used for more than 12 hours continuously

measuring units from FPM to Hz, press and release the FPM/Hz
key. Units will alternate with each press and release.
Flash Rate (Frequency Setting) in Internal Mode -
You can set the flash rate by turning the dial in the center of the
unit. To increase the flash rate, turn the dial in the clockwise direc-
tion. To decrease the flash rate, turn the dial in the counter-clock-
wise direction. For small adjustments, turn the dial slowly. For
quick adjustments, rotate the dial quickly. The flash rate range
and resolution will be different according to the selected measur-
ing range.
One function of a stroboscope is to provide a “stopped” image
of a rotating target when the flash rate of the stroboscope has
matched the rotational speed of the target object. The strobo-
scope will show a single image when the flash rate is set to a
lesser multiple of the true RPM (1/2,1/3,etc.) When the flash rate
is increased to a higher multiple (2,3,etc.), multiple images will
appear. To find the true RPM of the target object, reduce the flash
rate to a lower multiple until only one image appears.
