A capacitance meter is a piece of electronic test equipment used to measure capacitance, [1] mainly of discrete capacitors. Depending on the sophistication of the meter, it may display the capacitance only, or it may also measure a number of other parameters such as leakage , equivalent series resistance (ESR), and inductance .
A typical motor start capacitor. A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run ...
Genteq is the rebranding of Regal's GE ECM, GE Capacitors and GE Commercial Motors divisions, which occurred in 2009. [ 1 ] Genteq develops and manufactures electronically commutated motors (ECM) and capacitors for residential and light commercial heating and air conditioning ( HVAC ) systems.
[19] [20] [21] A capacitor-start, capacitor-run motor has two separate capacitors, one for starting the motor, and another for running it, and has a centrifugal switch to disconnect the starting capacitor, or a back-EMF relay connected in parallel with the auxiliary winding of the motor. This motor provides high starting torque and high efficiency.
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.
Handheld LCR meters typically have selectable test frequencies of 100 Hz, 120 Hz, 1 kHz, 10 kHz, and 100 kHz for top end meters. The display resolution and measurement range capability will typically change with the applied test frequency since the circuitry is more sensitive or less for a given component (i.e., an inductor or capacitor) as the ...
