  2. Multimeter - Wikipedia

    en.wikipedia.org/wiki/Multimeter

    The meter comprised a moving coil meter, voltage and precision resistors, and switches and sockets to select the range. The first Avometer had a sensitivity of 60 Ω/V, three direct current ranges (12 mA, 1.2 A, and 12 A), three direct voltage ranges (12, 120, and 600 V or optionally 1,200 V), and a 10,000 Ω resistance range. An improved ...

  4. Mirror galvanometer - Wikipedia

    en.wikipedia.org/wiki/Mirror_galvanometer

    This moving coil galvanometer is mainly used to measure very feeble or low currents of order 10 −9 A. To linearise the magnetic field across the coil throughout the galvanometer's range of movement, the d'Arsonval design of a soft iron cylinder is placed inside the coil without touching it. This gives a consistent radial field, rather than a ...

  5. Protective relay - Wikipedia

    en.wikipedia.org/wiki/Protective_relay

    "Moving coil" meters use a loop of wire turns in a stationary magnet, similar to a galvanometer but with a contact lever instead of a pointer. These can be made with very high sensitivity. Another type of moving coil suspends the coil from two conductive ligaments, allowing very long travel of the coil.

  6. Avometer - Wikipedia

    en.wikipedia.org/wiki/Avometer

    The Model 8 Mark V, 6 & 7 were provided with an "OFF" position on the DC switch which both disconnected the meter's terminals and short-circuited the moving coil. AVOmeters designed from 1936 onwards were fitted with an overload cut-out operated by the moving coil frame hitting either forward or reverse sprung end stops. [13]

  7. Voltmeter - Wikipedia

    en.wikipedia.org/wiki/Voltmeter

    A moving coil galvanometer can be used as a voltmeter by inserting a resistor in series with the instrument. The galvanometer has a coil of fine wire suspended in a strong magnetic field. When an electric current is applied, the interaction of the magnetic field of the coil and of the stationary magnet creates a torque, tending to make the coil ...
