Introduction
The CI-6555 Charge Sensor measures voltages
from sources where the total amount of available
charge is very small, for example, many
electrostatics experiments. It is essentially a voltage
amplifier with extremely high input resistance.
Whereas a typical digital multimeter has an input
resistance of 10 megaohms (10
7
ohms), the Charge
Sensor has an input resistance of at least 10
12
ohms.
Coupled with a ScienceWorkshop
®
Computer
Interface, the Charge Sensor can be used as an
electronic version of the familiar laboratory
electroscope. Unlike the traditional electroscope
however, the Charge Sensor can make quantitative
measurements as well as indicate charge polarity.
