The self diagnostics are run automatically by the analyzer whenever the instrument is turned on, but the test can also be run by the operator at will. To initiate a self diagnostic test during operation, use the UP/DOWN key to scroll through the MAIN MENU to the SELF–TESTand Enter. The screen will follow the running of the diagnostic.

RUNNING DIAGNOSTIC

Testing Preamp — Cell

When the testing is complete, the results are displayed.

Power: OK Analog: OK

Cell: 2 Preamp: 3

The module is functioning properly if it is followed by OK. A number indicates a problem in a specific area of the instrument. Refer to Chapter 5 Maintenance and Troubleshooting for number-code information. The results screen alternates for a time with:

Press Any Key

To Continue...

Then the analyzer returns to the initial System screen.

4.3.6 The Model Screen

Scroll through the MAIN MENU to MODEL and Enter. The screen displays the manufacturer, model, and software version information.

4.3.7 Checking Linearity with ALGORITHM

Use UP/DOWN control to select ALGORITHM, and Enter.

sel rng to set algo:

—> Ø1 Ø2 Ø3

<—

Use the UP/DOWN Control to select the range: 01, 02, or 03. Then press Enter.

Gas Use: CO2

Range: Ø — 10%

Enteragain.

Algorithm setup:

VERIFY SET UP

Use UP/DOWN key to select and Enter VERIFY to check whether the linearizationhasbeenaccomplishedsatisfactorily.
