Physics Labs with Computers, Vol. 1Student WorkbookTutorial Activities: Economy Force Sensor 012-07000ACalibrate the sensorThe general method for calibrating the force sensor is as follows:1. In the Experiment Setup window, double-click the sensor’s icon.• Result: In DataStudio, the Sensor Properties window opens. Click the ‘Calibration’ tab. InScienceWorkshop, the Sensor Setup window opens.2. Calibrate the software.• First, arrange the sensor as it will used for making measurements but DONOT apply a force to the sensor. Press the ‘tare’ button to zero the sensor.• Second, check the voltage under ‘Current Reading’ in DataStudio or next to‘Cur Value:’ in ScienceWorkshop. When the voltage stabilizes, click the ‘Take Reading’button under ‘Low Point’ in DataStudio or the ‘Read’ button in the row for ‘Low Value:’in ScienceWorkshop. Enter ‘0’ as the force value.• Third, use the object of known mass to apply a pulling force on the hook. When thevoltage stabilizes, click the ‘Take Reading’ button under ‘High Point’ in DataStudio or the‘Read’ button in the row for ‘High Value:’ in ScienceWorkshop. Enter the force value. Forexample, enter ‘9.8’ for a one kilogram mass.3. Click ‘OK’ to return to the Experiment Setup window.A - 24©1999 PASCO scientific
