6.2.1. Setting up the sensor to display the user's chosen
wavelengths.
The absorption of the detector coating varies somewhat
with wavelength. The correction curve for the absorber
is stored in the sensor EEROM. This correction curve
ensures that the power reading is correct at all laser
wavelengths.
In order to simplify changing from one laser wavelength
to another, the user can program up to 6 different
wavelengths to be available from the screen menu.
Please use the following procedure to set the
pyroelectric or PD10 & PD10-PJ sensor to your laser
wavelengths.
1. From the main display, select "Laser" and enter.
2. Use the up/down navigation keys to select the first
wavelength desired. Press the right navigation key.
3. Change the wavelength value by pressing the
up/down navigation keys to change each number and
the right/left navigation keys to move to the next
number. After you are finished, press "Save" and then
the Enter key.
4. Repeat step 3 for other wavelengths desired. When
finished press the Enter key. Those values for which
