Figure 2-2: Illustration of Normal Display

If TEST is pushed, the upper center display cycles through the menu of test parameters, e.g. Sample flow.

CAL is used to initiate span setting using sample gas, such as during a formal calibration.

Pushing MSG will cause a message to appear on the upper center display.

Pushing CLR will erase a message, provided the condition causing the message has ceased.

Pushing SETUP changes the function of the push buttons and is used for setting basic parameters as described in Section 4.

2.2.3 Status LED’s

The three status LED’s to the right of the display indicate the general status of the Model 300M Analyzer. The green SAMPLE LED indicates the sampling status. The yellow CAL LED indicates the calibration status. The red FAULT LED indicates the fault status. Table 2-5summarizes the meanings of the status LED’s.
