Activating/Deactivating the Source
Choose
On/Off
to activate or deactivate light emission. When the source is
active, the LED on the module front panel lights up and the Status indicator
blinks and then appears in red with two right-pointing arrows. Once the
source is deactivated, the LED on the module front panel will turn off, the
Status indicator will blink, then appear in black, and the arrows will
disappear.

Note:
To obtain optimum stability, a laser source should be allowed to warm up
for 60 minutes.
Selecting a Wavelength
There are four ways of selecting a wavelength for testing. You can make a
direct entry, select a wavelength from an already existing list, use the slider
or use incremental selection.
Direct Entry
Any desired wavelength within the operational limits of the source can be
entered directly by editing the value appearing in the
λ
field. Pressing
Enter
signals the completion of an entry.
Selection from a Stored List
To select a wavelength in the list of existing wavelengths, simply use the
drop-down menu in the
λ
field and select the desired wavelength.
