  2. Fluke Corporation - Wikipedia

    en.wikipedia.org/wiki/Fluke_Corporation

    Fluke Corporation is an American manufacturer of industrial test, measurement, and diagnostic equipment, including electronic test equipment. It was started in 1948 by John Fluke while he was employed at General Electric .

  3. Calibration - Wikipedia

    en.wikipedia.org/wiki/Calibration

    The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...

  4. Network analyzer (electrical) - Wikipedia

    en.wikipedia.org/wiki/Network_analyzer_(electrical)

    ZVA40 vector network analyzer from Rohde & Schwarz.. A network analyzer is an instrument that measures the network parameters of electrical networks.Today, network analyzers commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h ...

  5. 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).

  6. Torque tester - Wikipedia

    en.wikipedia.org/wiki/Torque_tester

    A key component of modern torque testers is the digital display. A digital display is used to measure the output signal from the transducer and calculates that reading into a torque value that is displayed on screen. In most cases the display and transducer are contained together inside a housing. This is known as a "Desktop Torque Tester".

  7. Time-domain reflectometer - Wikipedia

    en.wikipedia.org/wiki/Time-domain_reflectometer

    Time-domain reflectometer for cable fault detection. A time-domain reflectometer (TDR) is an electronic instrument used to determine the characteristics of electrical lines by observing reflected pulses.

  8. Optical time-domain reflectometer - Wikipedia

    en.wikipedia.org/wiki/Optical_time-domain...

    It is the optical equivalent of an electronic time domain reflectometer which measures the impedance of the cable or transmission line under test. An OTDR injects a series of optical pulses into the fiber under test and extracts, from the same end of the fiber, light that is scattered (Rayleigh backscatter) or reflected back from points along ...

  9. Survey meter - Wikipedia

    en.wikipedia.org/wiki/Survey_meter

    Alpha scintillation probe under calibration. The most commonly used hand-held survey meters are the scintillation counter, which is used in the measurement of alpha, beta and neutron particles; the Geiger counter, widely used for the measurement of alpha, beta and gamma levels; and the ion chamber, which is used for beta, gamma and X-ray measurements.
