LAMBDA DG-4 PLUS & DG-5 PLUS OPERATION MANUAL – REV. 3.05B (20131009)

8.
Turn on the power to the lamp subsystem using the switch labeled LAMP on the back
panel of the Lambda DG-4 cabinet. Due to the current draw during lamp ignition, it is
important to power up the LAMP first (before the MAIN switch is turned on) to avoid
damage to the circuitry of the other Lambda DG-4 subsystems. This same precaution
applies to the order in which you power up other electronic and computer equipment that
might be powered from or grounded to the same circuit as the one used for the Lambda
DG-4. GO DIRECTLY TO THE NEXT STEP! DO NOT OPERATE THE LAMP FOR
MORE THAN A FEW SECONDS WITHOUT TURNING ON THE MAIN POWER
SWITCH!
9.
Within a few seconds of turning on the LAMP switch turn on the power to the optical
path and controller subsystems using the switch labeled MAIN on the back panel of the
Lambda DG-4 cabinet. The Lambda DG-4 will boot up and briefly display the
initialization screen followed by the MAIN MENU (shown on top of next page).
10.
The Lambda DG-4 is under LOCAL (keypad) control upon start-up, as indicated by the
words “INPUT - MANUAL” on the MAIN MENU (see above). MOVE ON COMMAND is
the active operational mode at start-up, which means that filters are selected by pressing
the numeric keys corresponding to the desired FILTER NUMBER (see EDIT A FILTER
NUMBER definition of this value). The default FILTER NUMBER upon start-up is “0”.
This setting will disrupt the optical pathway within the Lambda DG-4 and prevent any
light output at the light guide port. The “0” FILTER NUMBER serves, then, as a
“shutter” whenever it is selected.
11.
Press the “1” key followed by ENTER. This FILTER NUMBER is pre-programmed at the
factory to cause the light to be directed through the FILTER HOLDER that is loaded into
position 1 and then onto the light guide with maximal light output (i.e., minimal
attenuation).
12.
Now experiment by selecting FILTER NUMBERS 0 through 4. Anytime you select a
single digit FILTER NUMBER you must complete the entry by pressing the ENTER key
or you must precede the single digit with a “0”. FILTER NUMBERS 0,1,2,3 and 4 are
pre-programmed to correspond with the closed “shutter” and the four FILTER
POSITIONS (with minimal attenuation), respectively.
Now that you have completed the “Make it Glow” section of the manual, you should be
familiar with the basic components and operation of the Lambda DG-4. To get set up for an
experimental application you will need to:
Install the LIGHT GUIDE into the OPTICAL HOLDER (if not already in place).
Install the OPTICAL HOLDER into the microscope using the appropriate adapter (if not
already in place).
Install the desired filters into the FILTER HOLDERS (if not already in place).
Program the desired FILTER NUMBERS.
Establish the desired interface between the Lambda DG-4 and your computer.
