Measures current without physical connection. Curve tracer. Applies swept signals to a device and allows display of the response. Cos Phi Meter. Measures the power factor. Distortionmeter. Measures the distortion added to a circuit. Electricity meter. Measures the amount of energy dissipated.
Time. Watch, a time measurement device. In the past, a common time measuring instrument was the sundial. Today, the usual measuring instruments for time are clocks and watches. For highly accurate measurement of time an atomic clock is used. Stopwatches are also used to measure time in some sports.
Electrical measurements are the methods, devices and calculations used to measure electrical quantities. Measurement of electrical quantities may be done to measure electrical parameters of a system. Using transducers, physical properties such as temperature, pressure, flow, force, and many others can be converted into electrical signals, which ...
Multimeter. Analog multimeter. Digital multimeter. A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [2][3] A typical multimeter can measure voltage, resistance, and current, [4] in which case can be used as a voltmeter, ohmmeter, and ammeter.
Electronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced. Use of electronic test equipment is essential to any serious work on electronics systems. Practical electronics engineering and ...

Below is the list of measuring instruments used in power engineering work. Cable Identifier measurement system. Name. Purpose. Cable locator. Diagnoses a damage along a HV cable. Contact resistance meter. Measures the contact resistance of a power switching devices. Circuit breaker analyzer.
Overview. The source measure unit (SMU), or source-measurement unit, is an electronic instrument that is capable of both sourcing and measuring at the same time. It can precisely force voltage or current and simultaneously measure precise voltage and/or current. An SMU instrument can source and sink power in all four quadrants.
