  2. Solenoid voltmeter - Wikipedia

    en.wikipedia.org/wiki/Solenoid_voltmeter

    Some manufacturers include a continuity test lamp function in a solenoid meter; these use the same probes as the voltage test function. This feature is useful when testing the status of contacts in energized circuits. The continuity light displays if the contact is closed, and the solenoid voltmeter shows voltage presence if open (and energized).

  3. Condition monitoring - Wikipedia

    en.wikipedia.org/wiki/Condition_monitoring

    Performance monitoring is a less well-known condition monitoring technique. It can be applied to rotating machinery such as pumps and turbines, as well as stationary items such as boilers and heat exchangers. Measurements are required of physical quantities: temperature, pressure, flow, speed, displacement, according to the plant item.

  4. Growler (electrical device) - Wikipedia

    en.wikipedia.org/wiki/Growler_(electrical_device)

    A growler is an electrical device primarily used for testing a motor for shorted coils. A growler consists of a coil of wire wrapped around an iron core and connected to a source of alternating current. When placed on the armature or stator core of a motor the growler acts as the primary of a transformer and the armature coils act as the ...

  5. Thermodynamic pump testing - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_pump_testing

    Then, the head on the pump is varied by some sort of adjustment such as throttling a discharge valve, utilizing different pump combinations in parallel, or adjusting well levels. [4] This allows the pump's performance to be tested across its range of operation as its head, and hence flow, is varied.

  6. Multimeter - Wikipedia

    en.wikipedia.org/wiki/Multimeter

    Inexpensive analog meters may have only a single resistance scale, seriously restricting the range of precise measurements. Typically, an analog meter will have a panel adjustment to set the zero-ohms calibration of the meter, to compensate for the varying voltage of the meter battery, and the resistance of the meter's test leads.

  7. Test light - Wikipedia

    en.wikipedia.org/wiki/Test_light

    A test light, test lamp, voltage tester, or mains tester is a piece of electronic test equipment used to determine the presence of electricity in a piece of equipment under test. A test light is simpler and less costly than a measuring instrument such as a multimeter , and often suffices for checking for the presence of voltage on a conductor.

  9. Troubleshooting - Wikipedia

    en.wikipedia.org/wiki/Troubleshooting

    Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
