DAD Test Function

Detector tests can be used as a step in the routine system validation of an
analytical instrument in a regulated laboratory.
The DAD test assesses the performance of your diode array detector. When
you select the DAD test from the Instrument menu (for LC3D and CE only) it
checks the instrument for intensity and wavelength calibration. When you
press Save the test results are automatically saved to the DADTest database, a
register file called DADTest.Reg located in the default instrument directory.

Review DAD Test Function

The Review DAD Test function in the data analysis View menu enables you to
review the DADTest.Reg file at any time. The file is protected by a checksum,
and is encoded into binary to ensure that it is not changed.
