List of electrical and electronic measuring equipment

Below is the list of measuring instruments used in electrical and electronic work. Name PurposeAmmeter (Ampermeter) Measures currentCapacitance meterMeasures the capacitance component Current clampMeasures current without physical connectionCurve tracerApplies swept signals to a device and allows display of the responseCos Phi MeterMeasures the power factor DistortionmeterMeasures the distortion added to a circuit Electricity meterMeasures the amount of energy dissipated ESR meterMeasures the equivalent series resistance of capacitorsFrequency counterMeasures the frequency of the current Leakage testerMeasures leakage across the plates of a capacitorLCR meter Measures the inductance, capacitance and resistance of a componentMegger tester Measures Resistance of an Winding of Motor or Generator And Measures Earthing's ResistanceMicrowave power meterMeasures power at microwave frequenciesMultimeterGeneral purpose instrument measures voltage, current and resistance (and sometimes other quantities as well)Network analyzer Measures network parametersOhmmeterMeasures the resistance of a componentOscilloscopeDisplays waveform of a signal, allows measurement of frequency, timing, peak excursion, offset, ... Psophometer Measures AF signal level and noise Q meter Measures Q factor of the RF circuitsTachometer Measures speed of motorsSignal analyzerMeasures both the amplitude and the modulation of a RF signalSignal generatorGenerates signals for testing purposesSpectrum analyserDisplays frequency spectrumSweep generatorCreates constant-amplitude variable frequency sine waves to test frequency response Transistor testerTests transistorsTube testerTests vacuum tubes (triode, tetrode etc.)WattmeterMeasures power in a circuitVectorscopeDisplays the phase of the colors in color TVVideo signal generatorGenerates video signal for testing purposesVoltmeterMeasures the potential difference between two points in a circuit.
