Calibrate/Calibration Tab

The calibration of a sensor controls how input to the sensor is converted to values with specific units. For instance, a Gas Pressure Sensor has a calibration that converts the raw output voltage of the sensor to kiloPascals (kPa), and a different calibration that converts voltages to mmHg.

Current calibration settings are shown in the Sensor Information tab in the Sensor Settings dialog. To view the calibration settings, choose Set Up Sensors from the Experiment menu and select your interface. Then, click the channel the sensor is connected to and select Sensor Information.

Most sensors do not need to be calibrated to provide good results. If you would like to calibrate your sensor for greater accuracy, you can get started by following the procedure below.

Calibrating a Sensor

To calibrate your sensor, choose Calibrate from the Experiment menu. Then, select the sensor you want to calibrate. Note: Calibrate will only be an option if there is a sensor that can be calibrated. Motion Detectors, for example, cannot be calibrated.

For more information, choose the type of calibration you wish to perform. There are three options:
