Diagnostics and Calibration
The Waters 2996 Photodiode Array Detector automatically runs a series of internal
diagnostics upon start up. The indicator LEDs on the front of the detector and messages at
the Millennium
32
Workstation show the results of the start up internal diagnostics
(Figure 1-8).
If you need to determine the cause of a problem during operation of the detector, you can
run the same internal diagnostics from the Millennium
32
Workstation. Additional
information about the performance of the detector is also available through the PDA
Calibration window, accessed from Run Samples in the Millennium
32
software.
If you encounter a problem that you cannot troubleshoot (Section 2.1, Diagnostics),
contact Waters Technical Service at (800) 252-4752, U.S. and Canadian customers only.
Other customers, call your local Waters subsidiary or your local Waters Technical Service
Representative in Milford, Massachusetts (U.S.A.) for assistance.
