5.9 Calibrate CO

(For PCA Models 20, 25, 30, 35, 50, 55, 60 & 65)

Material Required:

•Calibration Gas Fixture (Section 5.2)

•Gas Cylinder, 500 ppm CO in air (Refer to Section 8.2)

•Gas Cylinder, CO (1000 ppm) and H2 (1000 ppm) in Nitrogen (Refer to Section 8.2)

Procedure:

1.Enter the Calibrate Menu Screen per Section 5.3. Then choose to calibrate the CO sensor.

2.At the conclusion of Step 1 the pump should start running.

3.Using the Gas Fixture shown in Figure 5-1, attach the CO calibration- gas cylinder to the analyzer’s GAS inlet.

4.Adjust the regulator of the calibration fixture for a flowmeter indica- tion of approximately 2 SCFH.

5.Wait until the MEASURED reading on the screen stabilizes (approxi- mately 3 minutes). Then use the st and keys to enter an APPLIED value* that equals the concentration which is stamped on the CO calibration-gas cylinder.

6.Press the key to calibrate the analyzer’s MEASURED value to that of the APPLIED value. At this time the Test Gas CO/H2 Screen is displayed.

*The calibration range for this screen is 250 – 1500 ppm. Any attempt to calibrate outside this range will cause the analyzer to display an error message.
