An electrostatic fieldmeter, also called a static meter is a tool used in the static control industry. It is used for non-contact measurement of electrostatic charge on an object. It measures the force between the induced charges in a sensor and the charge present on the surface of an object.
Tektronix 7854 oscilloscope with curve tracer and time-domain reflectometer plug-ins. Lower module is a mainframe of the series Tektronix TM500 and has a digital voltmeter, a digital counter, an old WWVB frequency standard receiver with phase comparator, and function generator. Electronic test equipment is used to create signals and capture ...

A field strength meter is actually a simple receiver. The RF signal is detected and fed to a microammeter, which is scaled in dBμ.The frequency range of the tuner is usually within the terrestrial broadcasting bands.
It detects this by the movement of a test charge due to the Coulomb electrostatic force on it. The amount of charge on an object is proportional to its voltage . The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are used with high voltage sources such as static electricity ...
In solid-state physics, especially for metals and semiconductors, the screening effect describes the electrostatic field and Coulomb potential of an ion inside the solid. Like the electric field of the nucleus is reduced inside an atom or ion due to the shielding effect , the electric fields of ions in conducting solids are further reduced by ...
