46 Chapter 4 Laser Diode Driver Module Operation
4.4.3 Grounding Consideration
The laser outputs of the module are isolated from chassis ground allowing either
output terminal to be grounded at the user's option.
4.5 Laser Module Operation
4.5.1 Quick Start
After the power-on sequence is complete, the 6000 goes to the Master display. To
set up a laser module, press the
MENU
button, then the
Modules
soft key, then
select the laser driver, and finally, the
Setup
soft key. At this point, the display
shows all laser parameters. Using the cursor keys and knob, select the desired
functions and set the parameter values. When finished, return to laser display with 


(previous) soft key.
Enter the desired set point value using the cursor keys or the knob. Press the
LDD
ON
key to operate the laser. The LED illuminates to indicate laser operation. To
turn the laser off, press the
LDD ON
key. For Model 6000M or 6000MF controllers,
use the
OSC ON
or
AMP ON
key to control the oscillator or amplifier outputs,
respectively.

photodiode current, or photodiode power.
SETUP
- Pushing the adjacent soft key activates the setup screen.
The bottom line on the display has 6 “LED” elements, each indicating a particular
state of the laser. They are defined as:
