Startup Display

When power is applied to the probe, the cell heater turns on. It takes approximately one half hour for the cell to heat to operating temperature. This condition is indicated by a "warm up" display on the LOI (Figure 6-1). This message will continue to display until the cell is up to operating temperature.

Operating Display

The normal operating display is the % O2 concentration. The "normal" display is shown in Figure 6-2.

Error

If there is an error condition at startup, an alarm message will be displayed. Refer to Section 8: Troubleshooting, to determine the cause of the error. Clear the error, cycle power, and the % O2 display should return.

LOI

The Local Operator Interface can be used to change the software and alarm settings, to adjust the high and low gas settings, and to initiate the calibration sequence. Refer to the LOI menu (Figure 6-4).
