| Description |
| The
LS310 contains (4) push-button switches, (2) display windows, (3)
3.5mm stereo jacks for connection, and an IEC-C8 2-pin AC power adapter
inlet. The four push-buttons control: Up, Down, Mode, and Display.
The Up/Down switches change frequency or phase, while the Mode switch
selects various operating modes, and the Display switch controls which
numeric parameter is displayed in the readout window. |

| Operating
Modes |
• Manual
In this mode the external sync input is not used or required. The flash
frequency of the strobe is controlled solely by the Up/Down buttons. This
mode can be very useful for general work, or for determining the frequency
of a moving/rotating object, driver, motor, fan, etc.
• Sync - Frequency
In this mode the external sync input is used to provide the base frequency
of the strobe. However the actual strobe frequency can be offset by a user
defined value. For example, if a frequency offset of +1.00Hz is used the
strobe will flash at a rate 1Hz higher than the sync frequency. As the signal
is swept across frequency, the strobe will always flash 1Hz higher than
the sweep frequency. This allows the user to view the diaphragm in a 1Hz
motion at any driven stimulus frequency. A very useful mode.
• Sync - Phase
In this mode the external sync input is used to provide the exact frequency
of the strobe. However the actual phase position of the flash can be offset/stepped
through the entire 360 degree period. This mode can be very useful in examining
the motional behavior across the entire periodic cycle of the driver. Resolution
/ step size is adjustable from 1 degree to 45 degrees.
• Flashlight
In this mode the strobe flashes at a high rate to provide general illumination.
This mode is useful when you wish to illuminate the object without any synchronous
flashing. The actual frequency can be changed thus providing a secondary
manual mode.
|
| Display Modes |
• Flash/Sec (Hz)
This mode displays the strobe frequency in flashes per sec, or Hertz.
• Flash/Min (RPM)
This mode displays the strobe frequency in flashes per min, or RPM.
|
 |
|
•
Frequency Offset (Hz)
This mode displays the strobe frequency offset in flashes per sec,
or Hertz.
• Phase Offset (Deg)
This mode displays the strobe phase offset in degrees. |

| Connections |
• Sync Input
The LS310 can sync to any periodic signal ranging from 0.5VRMS to
300VRMS. The LS310 employs patented circuitry which adjusts itself
to the incoming signal strength instantaneously. The Sync input can
be attached directly to the driver speaker terminals to obtain the
sync.
• Trigger Output
The trigger output by default provides a pulse identical to the flash
pulse rate of the strobe. Future enhancments provide for other special
trigger applications and options as well.
• RS-232 Interface
The RS-232 interface allows connection to a PC for update of firmware
and modification of control parameters through the Win32 application
software, or for custom programming by the user. |
