Performing Internal Wavelength Referencing
The T200S internal referencing ensures optimum adjustment of the laser source as soon as
the laser starts.
The T200S automatically performs internal referencing during the startup routine (see
Turning on the T200S and Accessing the GUI on page 16).
In addition, you can perform a new internal referencing at any time, as explained in the
following procedure.
If the button appears on screen, it means that the T200S needs internal referencing: the
T200S is fully usable but performances are not guaranteed.
To perform an internal wavelength referencing:
Do one of the following:
³
In the task bar, touch the button to display the Settings window and select the
Instrument tab.
In the Wavelength reference area, touch the Start wavelength reference button.
³
Touch the button if it is displayed on screen.
The referencing process starts, any other operation on the T200S is disabled.
Once completed, the information message disappears.
