Multi-Sensor Span Calibration

This lets you perform a span calibration on multiple sensors simultaneously. It requires using the
appropriate span gas and that the concentration labeled on the gas cylinder matches the concentration
programmed in the AreaRAE Plus/Pro.
Teflon tubing must be used to test or calibrate the PID sensor. Follow the steps described here to perform
a multi-sensor span calibration:
1. Attach the "T" tube and connect gas to the AreaRAE Plus/Pro.
2. Start the flow of gas and then either press [Y/+] to begin calibration or wait for calibration to start
automatically once the sensor "senses" the gas. A countdown screen is shown. You can abort the
calibration at any time during the countdown by pressing [N/-].
If the calibration reaches its conclusion, it shows the sensor names and tells you whether the calibration
passed or failed, followed by the sensor readings.
Note: If there are other sensors to be calibrated at this stage, the screens will guide you through the
process.
