Charge Sensor
 This is used as an electronic electroscope. Unlike a
traditional electroscope, the Charge Sensor can make quantitative
measurements. Numerical measurements improve many electrostatics
experiments, such as charging by induction, charging by friction, and
charging by contact. The sensor can also be used to measure charge polarity.
An extremely high impedance voltage sensor with a 0.01 µF input capacitor
makes these measurements possible. The sensor has three operating ranges and
a zeroing switch to discharge the input capacitor.
