Sensor Calibration

This procedure spans the optional carbon monoxide high sensor (4,001 to

20,000 ppm) to a known gas level.

6.11.1. Material Required

•

Calibration Kit (P/N 0024-7059)

•

Gas Cylinder (4,000 ppm CO in Air, P/N 0024-1155)

Figure 6-12. Gas Sensor Calibration Equipment

6.11.2. Procedure

1. If not already done, turn ON the analyzer and display the

CALIBRATION LIST screen (refer to Calibration on page 66).

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

the CALIBRATE CO-HI screen.

NOTE:

“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 6-12.

4. Use the ▲▼ and

◄►

buttons to enter an applied value that exactly

equals the concentration on the CO cylinder.
