Using the Attenuator
Setting Up the Attenuation
unknown source (you alter the wavelength until the displayed
attenuation matches the measured attenuation).
There are two sets of wavelength calibration data, one made in the
factory, individually, for your instrument. The user defines the other.
For more details on these topics, see “Selecting the Wavelength
Calibration and Its Function” on page 67.
The wavelength is shown at the top right of the display.

Edit the wavelength using the modify keys.
To edit the wavelength,
1. press
λ, and
2. edit the value using the Modify keys (see “Using the Modify
Keys” on page 29).
Resetting the Wavelength
To reset the wavelength, press and hold A
TT until the value resets
(this takes approximately two seconds). The wavelength resets to
1310nm.
