ABSTRACT:
An instrument for non-contact measurement of electrostatic fields and related parameters, such as electrostatic potential, voltage and charge density of a charged object, includes a sensor for sensing the electrostatic field produced by the object and for producing an electrical signal, a display for producing a visual readout related to the electrical signal and a range scaling circuit for coupling the sensor to the display. The range scaling circuit is coupled to logic which switches the range scaling circuit and the display back and forth between two ranges, one for relatively higher strength field measurements and one for relatively lower strength field measurements. Because the distance at which the instrument is held from the charged object to achieve an accurate reading depends upon the strength of the field, the range scaling circuit is also coupled to circuitry which indicates the appropriate distance from the charged object at which the instrument must be held to provide an accurate measurement.
