An electrostatic voltmeter measures surface voltage without transferring excess current charge, ensuring accurate measurements of material tension. It requires no contact and can cancel the electric field between the probe and surface, minimizing arcing and achieving high accuracy. It is commonly used in the industrial sector for various applications. An electrostatic voltmeter measures the surface […]
A digital voltmeter is a device used to measure the relative output voltage of electronic appliances, and is important for anyone doing electrical work. Digital models are considered superior to analog models, and can measure voltages from picovolts to megavolts and frequencies between zero and several megahertz. They are used in a variety of applications, […]
A vector voltmeter measures both the level and phase difference between two voltage sources. It is used to measure the frequency and phase response of electronic amplifiers and can confirm the phase difference between outputs in a three-phase power source. Scalar quantities have magnitude only, while vector quantities have both magnitude and direction. Vector cancellation […]
