Controls and Components Located on the Rear Panel
(1) LASER DISABLE SWITCH
This switch shuts down the scanning Laser Beam.
(2) LASER EMISSION INDICATOR
This is a red LED lamp that illuminates when the scanning Laser Beam is present.
(3) POWER ENTRY MODULE
The FUSE HOLDER, the POWER SWITCH, and the AC LINE CONNECTOR are contained in this module.
(4) CERTIFICATION LABEL
This label certifies compliance with CDRH regulations.
(5) REAR PANEL WARNING LABEL
This label warns of the presence Laser Radiation inside the instrument. CAUTION - THERE ARE NO USER SERVICEABLE PARTS INSIDE THE INSTRUMENT, DO NOT OPEN.
(6) WARNING LOGOTYPE
This label specifies the wavelength and maximum power output of the laser radiation emitted from the instrument.
(7) LCD DISPLAY
Displays Specimen Elongation in either inches or millimeters when the instrument is in the RUN Mode, and displays the value of various operating parameters when the instrument is in the SETUP Mode.
(8) ZERO BUTTON
Pressing the ZERO button offsets the current value of Specimen Elongation to zero and displays "OFFSET" on the LCD DISPLAY. Subsequent elongation measurements then become relative to this new zero point. Pressing the ZERO button again removes the offset.
(9) SELECT BUTTON
While in RUN MODE, pressing this button simultaneously with the SCROLL BUTTON forces the
Model LE-05 into the SETUP MODE. The SELECT BUTTON is then used to select and accept major items from the SETUP MENU.
(10) SCROLL BUTTON
While in RUN MODE, pressing this button simultaneously with the SELECT BUTTON forces the Model LE-05 into the SETUP MODE. The SCROLL BUTTON is then used to change the value of the "selected" item in the SETUP MENU. The SELECT BUTTON must then be pressed to "accept" the new value of the "selected" item.
(11) RUN BUTTON
While in SETUP MODE, pressing this button returns the Model LE-05 to the RUN MODE.
(12) SIGNAL OUTPUT JACK
A BNC connector is provided for monitoring the reflections coming back from the specimen using an oscilloscope. This is especially useful for initial setup or troubleshooting.
(13) RS-232 JACK
A modular connector is provided to allow RS-232 I/O connection to a Host computer.
(14) EXTERNAL RECEIVER JACK
A modular connector is provided for this optional accessory.
(15) ANALOG OUTPUT JACK
A modular connector is provided here also. It allows connections to the ANALOG OUTPUT (a ±5v or
±10v DC signal proportional to Specimen Elongation), and connections for providing a 5v level to actuate the optional REMOTE LASER DISABLE function.
