Diagnostics
The ProStar 335 detector performs some self-diagnostics. For
example, when the ProStar 335 is turned on, start-up diagnostics
are performed, whereby the integrity of the hardware is checked
to ensure the detector is functioning properly. A self-calibration
(zero order) is then performed, and detector levels are adjusted.
(This can only be performed after the D
2
lamp is turned on). If a
fault is detected, the error is displayed in the software.
Extended diagnostics tests are available using the ProStar 335
PolyVerify software. Extended diagnostics are those test
procedures that may pinpoint component level electronic
malfunctions or failures indicated by the error messages. These
tests can be performed by the user, but for many cases, will
require the services of a skilled technician or a Varian customer
support representative. Information on using the ProStar 335
PolyVerify software is not included in this manual. For assistance
with using the ProStar 335 PolyVerify software, refer to the online
help.
