10.1 Overview

The Model 300 has been designed to rapidly detect possible problems and allow their quick evaluation and repair. During operation, the analyzer continuously performs self-check diagnostics and provides the ability to monitor the key operating parametersof the instrument without disturbing monitoring operations. These capabilities will usually allow the quick isolation and resolution of a problem.

A systematic approach to troubleshooting will generally consist of the following four steps, performed in order:

1.Confirm the proper operation of Fundamental Instrument sub-systems (Power Supplies, CPU, Display).

2.Note any warning messages and take corrective action as required.

3.Examine the values of all TEST functions and compare to Factory values. Note any major deviations from the factory values and take correction action as required;

4.Address any Dynamic (Sample related) problems.

The following sections provide a guide for performing each of these steps. Figure 1.6 in this manual shows the general layout of components and sub-assemblies in the analyzer and can be referenced in performing the checks described in the following sections.
