The Zero button on the front panel is used to enter the zero calibration function. Zero calibration can be performed in either the automatic or manual mode. In the automatic mode, an internal algorithm compares consecutive readings from the sensor to determine when the output is within the accept- able range for zero. In the manual mode, the operator determines when the reading is within the acceptable range for zero. Make sure the zero gas is connected to the instrument. If you get a CELL FAILURE message skip to section 4.4.1.3.

4.4.1.1Auto Mode Zeroing

Press Zero to enter the zero function mode. The screen allows you to select whether the zero calibration is to be performed automatically or manu- ally. Use the Δ∇ arrow keys to toggle between AUTO and MAN zero settling. Stop when AUTO appears, blinking, on the display.

Zero:Settling:AUTO

<ENT> To Begin

Press Enter to begin zeroing.

####PPM Zero Slope=#### ppm/s

The beginning zero level is shown in the upper left corner of the dis- play. As the zero reading settles, the screen displays and updates information on Slope (unless the Slope starts within the acceptable zero range and does not need to settle further).

Then, and whenever Slope is less than 0.08 for at least 3 minutes, instead of Slope you will see a countdown: 5 Left, 4 Left, and so fourth. These are five steps in the zeroing process that the system must complete, AFTER settling, before it can go back to Analyze.

####PPM Zero

4 Left=### ppm/s

The zeroing process will automatically conclude when the output is within the acceptable range for a good zero. Then the analyzer automatically returns to the Analyze mode.

4.4.1.2Manual Mode Zeroing

Press Zero to enter the Zero function. The screen that appears allows you to select between automatic or manual zero calibration. Use the Δ∇ keys to toggle between AUTO and MAN zero settling. Stop when MAN appears, blinking, on the display.
