4.3.5 System Self-Diagnostic Test
The Model 3000TA-XL-EU has a built-in self-diagnostic testing
routine. Pre-programmed signals are sent through the power supply,
output board and sensor circuit. The return signal is analyzed, and at the
end of the test the status of each function is displayed on the screen,
either as OK or as a number between 1 and 3. (See System Self
Diagnostic Test in Chapter 6 for number code).
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 any time. In addition, web enabled instruments can initiate a
self diagnostic test remotely from a computer. See Section 5.6.
