  2. Electrostatic fieldmeter - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_Fieldmeter

    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.

  3. Battery tester - Wikipedia

    en.wikipedia.org/wiki/Battery_tester

    Battery tester. A battery tester is an electronic device intended for testing the state of an electric battery, going from a simple device for testing the charge actually present in the cells and/or its voltage output, to a more comprehensive testing of the battery's condition, namely its capacity for accumulating charge and any possible flaws affecting the battery's performance and security.

  4. Battery indicator - Wikipedia

    en.wikipedia.org/wiki/Battery_indicator

    ESR meters fitted with protective diodes cannot be used, a battery will simply destroy the diodes and damage itself. An ESR meter known not to have diode protection will give a reading of internal resistance for a rechargeable or non-rechargeable battery of any size down to the smallest button cells which gives an indication of the state of charge.

  5. Coulometry - Wikipedia

    en.wikipedia.org/wiki/Coulometry

    Coulometry is the measure of charge, thus named after its unit the coulomb. Michael Faraday, known for his work in electricity and magnetism, made critical contributions to the field of electrochemistry. He discovered the laws of electrolysis, and in his recognition is the eponym of the Faraday constant.

  6. Coulombmeter - Wikipedia

    en.wikipedia.org/wiki/Coulombmeter

    The inner electrode, which is electrically isolated from the shield, is connected to a meter to measure the charge. [1] In the field of semiconductor design, a coulombmeter consists of a meter used in combination with a metal probe tip to pinpoint locations of excess charge on, for instance a semiconductor device. This application of a ...

  7. Dummy load - Wikipedia

    en.wikipedia.org/wiki/Dummy_load

    A dummy load is a device used to simulate an electrical load, usually for testing purposes.In radio a dummy antenna is connected to the output of a radio transmitter and electrically simulates an antenna, to allow the transmitter to be adjusted and tested without radiating radio waves.

  8. Test method - Wikipedia

    en.wikipedia.org/wiki/Test_method

    A test method is a method for a test in science or engineering, such as a physical test, chemical test, or statistical test. It is a definitive procedure that produces a test result. [ 1 ] In order to ensure accurate and relevant test results, a test method should be "explicit, unambiguous, and experimentally feasible.", [ 2 ] as well as ...

  9. Electrometer - Wikipedia

    en.wikipedia.org/wiki/Electrometer

    The alternating current signal produced by the flow of this charge is amplified and used as an analogue for the DC voltage applied to the capacitor. The DC input resistance of the electrometer is determined solely by the leakage resistance of the capacitor, and is typically extremely high, (although its AC input impedance is lower).
