3.7 Phase Delay
The DELAY button adjusts the phase shift of the fl ash with
respect to time. There are two modes: INTERNAL and
EXTERNAL (PBL model only).
3.7.1 Internal Phase Delay
Also referred to as JOG. Once the fl ash rate has been adjusted to
give a stopped motion image, the PHASE DELAY button may be
used to increase or decrease the phase of the image with respect
to its original position. Use the PHASE DELAY button to bring a
reference mark, such as a key way, into your line of sight.
To adjust the phase or jog the image, press the DELAY button.
PHASE will be displayed on the bottom line of the LCD display
and the current fl ash rate will be displayed on the top line. Turning
the knob adjusts the phase of the stopped image. It is a relative
adjustment. Press the DELAY button again to exit this mode.
3.7.2 External Delay (PBL Model ONLY)
The DELAY button has no function in External mode on the DBL
model stroboscope.
On the PBL model stroboscope there are three External Delay
Modes: Phase Delay, Time Delay, and Auto (Virtual RPM).
These modes are only active if an external trigger source is plugged
into the unit. The EXTernal icon must appear on the display.
Pressing the DELAY button cycles through the following modes:
In the External Phase Delay mode the fl ash is delayed 0.1 to 359.9
degrees after each external trigger pulse. The display will show
the delay in degrees on the top line and will indicate
PHASE on
the lower line. The knob adjusts the amount of delay in degrees,
counterclockwise to increase and clockwise to decrease.
