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.
Single-Sensor Span 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 from the list.
3.
Connect the "T" tube and connect it to a source of calibration gas.
4.
Verify that the displayed calibration value meets the concentration label on the gas
cylinder.
5.
Start the flow of calibration gas.
