Service And Troubleshooting - Teledyne T200 User Manual

SERVICE AND TROUBLESHOOTING

This section contains methods to identify the source of performance problems with the
analyzer and procedures to service the instrument.
Note
The analyzer has been designed so that problems can be rapidly detected, evaluated and
repaired. During operation, it continuously performs diagnostic tests and provides the
ability to evaluate its key operating parameters without disturbing monitoring operations.
A systematic approach to troubleshooting will generally consist of the following five steps:
1. Note any Alerts and take corrective action as necessary (see Table 5-3).
2. Examine the values of all basic functions in the Dashboard and compare them
to factory values. Note any major deviations from the factory values and take
corrective action.
3. Use the internal electronic status LEDs to determine whether the electronic
communication channels are operating properly.
