Single Sensor Span
Instead of performing a span calibration on multiple sensors simultaneously, you can select a single
sensor and perform a span calibration.
Note: If a calibration icon (bottle with bottom portion filled in) is shown next to any of the sensors, it
means that the sensor is due for a full calibration.
To perform span calibration of an individual sensor, follow these steps:
1. At the Calibration Menu, select "Single Sensor Span."
2. Select a sensor to calibrate from the list.
3. Install the "T" tube and connect it to a source of calibration gas.
4. Verify that the displayed calibration value meets the concentration specified on the gas cylinder.
5. Start the flow of calibration gas.
6. Press [Y/+] to start calibrating or wait for calibration to start automatically.
7. A countdown screen appears. You can abort the calibration at any time during the countdown by
pressing [N/-].
Note: Dotted line indicates automatic progression.
