Physics Labs with Computers, Vol. 1Student WorkbookTutorial Activities: Charge Sensor 012-07000AStart recording data• Connect the alligator clips of the sensor’s cable assemblyto the inner and outer baskets of the Faraday Ice Pail.• Press the zero button on the sensor to discharge the inputcapacitor.• In DataStudio, click the ‘Start’ button ( ). InScienceWorkshop, click the ‘REC’ button ( ).• Briskly rub the two Charge Producers together. Lowerone of the Charge Producers into the inner basket of theFaraday ice pail. Watch the results on the Meter display.Remove the first Charge Producer and lower the otherCharge Producer into the inner basket.Stop recording data.• Click ‘Stop’ to end data recording.Tips for using the Charge Sensor• Plug the Charge Sensor directly into the interface. Avoid using the interface cable ifpossible.• Mount the sensor on a threaded rod (such as the SA-9242 Pulley Mounting Rod) to holdthe sensor steady.• Put the sensor and interface box as far away from the equipment as possible.• Wrap the sensor case in aluminum foil.A - 22©1999 PASCO scientific
