Section 7 Maintenance
7.1 Overview
The analyzer is designed for automatic trouble-free operation under the continuous
supervision of the internal computer. As described in Sections 4 and 5, a series of alarms are
presented on the hand held keypad and the GUI if an operation or function is not performing
in the appropriate manner to alert the user that a problem exists. A detailed discussion of
service protocols is presented in Section 8.
Routine Preventative Maintenance of the analyzer consists of a periodic performance of the
Maintenance Check-out Procedure
(Section 7.2). Routine maintenance will correspond to
tape usage, which is 4 - 6 weeks for most applications.
On a periodic basis, it will be necessary to replace certain components of the system such as
the sensing tape and the filter element. Replacement procedures for these items are
described in Section 7.3-7.6.
