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.
