Figure 17-11 Connections for Calibration
3. Fill the gas bottle with a standard gas of certain CO
2
content (4% to 6%), and
input the gas to the monitor.
4. Open the CO2 USER MAINTAIN menu, and set the CO
2
field to a value,
which is the same with the CO
2
content of the gas bottle.
5. When the CO2 USER MAINTAIN menu displays the currently measured CO
2
content, wait until a stable reading is indicated, and then select the CONFIRM
CAL option to start calibrating the CO
2
module.
6. If the calibration succeeds, “CALIBRATE SUCCESS!” will be displayed in the
CO2 USER MAINTAIN menu. If fails, “CAL FAIL, TRY AGAIN!” will be
displayed, and re-calibration is required.
7. Select the EXIT option to exit the CO2 USER MAINTAIN menu.
