Xcalibur Diagnostics for the PDA Detector
Use the diagnostics program to check the operation of the PDA detector, calibrate the
detector, and view the event log. To perform diagnostics from the Xcalibur data system, your
detector must be connected to the data system computer, configured as part of an instrument,
and turned on. For information on configuring the PDA detector, see
Calibrating the PDA Detector
To calibrate your PDA detector, perform the following procedures:
•
Performing a Wavelength Calibration
•
Performing a Dark Current Calibration
Performing a Wavelength Calibration
The alignment of the spectrum on the diode array is dependent upon the physical alignment
of various components of the optical bench. The alignment can become offset if the detector
is sharply jolted, for example, in shipping. Such bumps and jars can slightly change the
wavelength of light reaching the photodiode array. Use the automated wavelength calibration
to determine wavelength accuracy and to correct for any misalignment.
