6.11. CO
HIGH
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.
