Measures the power factor Distortionmeter: Measures the distortion added to a circuit Electricity meter: Measures the amount of energy dissipated ESR meter: Measures the equivalent series resistance of capacitors Frequency counter: Measures the frequency of the current Leakage tester: Measures leakage across the plates of a capacitor LCR meter
The LCD shows voltage; current; true, reactive, and apparent power; power factor (for sinusoidal waveform); energy consumed in kWh; and hours connected. Some models display estimated cost. [1] Having a NEMA 5-15 plug and receptacle, and rated for 115 VAC (maximum 125 VAC), [2] the Kill A Watt is sold for the North American market.
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.
Clamp probes are used with some meters to measure electrical power and energy. The clamp measures the current and other circuitry the voltage; the true power is the product of the instantaneous voltage and current integrated over a cycle.
A power cable is an electrical cable, an assembly of one or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power . Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed.
Agilent Technologies was created in 1999 as a spin-off of several business units of Hewlett-Packard [12] including test & measurement, optics, instrumentation and chemical analysis, electronic components, and medical equipment product lines.
A SMU integrates a highly stable DC power source, as a constant current source or as a constant voltage source, and a high precision multimeter. It typically has four terminals, two for source and measurement and two more for kelvin, or remote sense, connection. Power is simultaneously sourced (positive) or sinked (negative) to a pair of ...
An external power supply, AC adapter or power brick, is a power supply located in the load's AC power cord that plugs into a wall outlet; a wall wart is an external supply integrated with the outlet plug itself. These are popular in consumer electronics because of their safety; the hazardous 120 or 240 volt main current is transformed down to a ...
