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 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.
