4.1Front Panel Controls

The front panel of the analyzer, shown in Figure 4-1, contains indicators and displays through which the computer module can be accessed. The upper left-hand side of the panel has an LED screen that displays the oxygen content of the sample in one-inch high numerals. This display can be brightened or dimmed by a potentiometer located directly behind the panel inside of the analyzer case. To access it, remove the top cover of the analyzer.

Figure 4.1: Analyzer front panel.

Below the LED screen are two red LED lights. Each will light to indicate whether the oxygen is being displayed in parts per million (PPM) or percent (%).

To the right of the LED screen is a flowmeter in standard cubic feet per hour (SCFH). The flow set knob adjusts the flow rate of the gas during calibration and zeroing.

In the panel below the LED screen is the LCD display. The five colored buttons below it are used to interface with the computer module in selecting modes, with the LCD
