Troubleshooting
- Primary Test: Plug the sensor into a Vernier interface and run the data-collection program. The units for the default readings are kPa and they should be reasonable for the altitude at which the sensor is being used (around 101 kPa at sea-level).
- Secondary Test: Connect a 20 mL syringe, from the Accessories Kit, to the sensor. Move the plunger of the syringe inward and check that the pressure readings increase.

Calibration
Caibrate? You do not have to perform a new calibration when using the Gas Pressure Sensor. The sensor is calibrated prior to shipping. If you would like to perform your own calibration, follow the steps described here. A one-point calibration at atmosphere is adequate for most applications. For more information, see How do I calibrate my sensor?
- Connect the Gas Pressure Sensor to an interface and launch the software.
- Initiate the calibration procedure and make sure the one-point calibration option is checked. This should be the default option.
- Enter the actual pressure as the known value for Reading 1.
- When the voltage reading stabilizes, click Keep.
- If you want to save the calibration onto the sensor, click the storage tab and save to the sensor.
- Click or tap Done to complete the calibration process.
