4.4.3 Single Sensor Calibration
This procedure determines the second point of the sensor
calibration curve for a single sensor. A standard reference
gas (span gas) is needed to perform this procedure. Table
2.2 shows the standard calibration gas which is typically
used as the span gas in the factory (connect the tube to the
sampling bag filled with the standard gas as shown in Figure
4-1).
1. Continuing from Step 4 or Step 6 of the previous
section, the display should show “Single Sensor
Calibration?” Press
[Y/+] key. The display shows all the
installed sensors in the monitor with the cursor blinking
at the first sensor location. Press
[Y/+] key to select the
high-lighted sensor and start the calibration, or press
[MODE] key momentarily to move to the next sensor
location.

countdown timer shows the number of remaining
seconds while the monitor performs calibration. When
