Troubleshooting... Incorrect Data

You may receive apparently incorrect data from the sensor.

Here are some things to check:

• Did you connect or change the range of the sensor after opening the file? This can result in the wrong calibration being used. Re-open the file with the sensors attached.
• Are the units not what you expected? Vernier sensors auto-ID to SI units, so double-check the units.
• Has the sensor been disconnected, or is there a bad connection? Check for this by changing the sensor conditions, such as pushing on a Force Sensor. Make sure that the sensor is firmly connected to the interface and that the interface is firmly connected to the computer. If the values change, the sensor is connected.
• Is the calibration bad? If a custom calibration is done incorrectly, the readings will be off. Reopen the file or select a different stored calibration. As a last resort you can perform your own calibration. See How to Calibrate a Sensor.
• The sensor you are using may not be working properly. Try using a different sensor.
