Calibration

cause the message “Bad Calibration Wrong CAL Entry” to appear in the following step.

5.Adjust regulator for a flowmeter indication of approximately 2 SCFH. Wait until the Measured reading stabilizes (approximately 3 minutes), and then press ENT to calibrate the NO2 Measured value to that of the Applied value. The message “Good Calibration” should briefly appear followed by the CALIBRATION LIST screen being re-displayed.

If the sensor’s output is low, but still usable, then the message “Good Calibration WARNING Low Sensor” will appear. The sensor will now be marked as being Low in the DIAGNOSTICS screen.

If the sensor’s output is too low to be usable, then the message “Bad Calibration Sensor End of Life, Entry Not Saved” will appear followed by the CALIBRATION LIST screen being re-displayed. The sensor will now be marked as being BAD in the DIAGNOSTICS screen.

6.Turn OFF regulator and remove gas cylinder.

5.10 CO-HI Sensor Calibration

This procedure spans the optional carbon monoxide high sensor (4,001 to 20,000 ppm) to a known gas level.

Material Required:

• Calibration Kit, P/N 24-7059

• Gas Cylinder: 4,000 ppm CO in Air, P/N 24-1155

Procedure:

1.If not already done, turn ON the analyzer and display the CALIBRATION LIST screen per Section 5.2.

2.Use the buttons to highlight CO-HI, and then press ENT to display the CALIBRATE CO-HI screen.

“Measured” is the current CO reading, while “Applied” is a known CO level that will be applied for calibration purposes.

3.Attach a 4,000 ppm CO cylinder to the regulator of the calibration fixture shown in Figure 5-2on Page 5-14.
