MultimeterA multimeter is a combined instrument for measuring several parameters in electrical circuits and changing electrical and electronic components. Multimeters are available in handheld and benchtop versions.
Benchtop multimeters typically have higher measurement accuracy and speed, a larger measurement range, and a larger number of measured quantities. Benchtop multimeters usually have the ability to measure using a 4-wire circuit. To implement different measurement modes, a mode switch is used. In hand-held devices, the mode switch is usually located in the middle of the device. In the simplest models of multimeters, this same switch is used to select the measurement range. Benchtop devices use push-button controls.
To implement different measurement modes, multimeters use different input jacks to connect the device to the circuit being measured. Most often, a separate set of connection sockets is available for the current measurement mode and when using a 4-wire connection scheme for measurement.
How to Use a Digital Multimeter to Test LED ChipsUseful Features of the AKTAKOM AM-1060 MultimeterHow to Use AM-1060 Multifunctional MultimeterFrequently Asked QuestionsWhat is the difference between an average-responding multimeter and a True RMS multimeter? A standard, low-cost multimeter measures the average rectified AC voltage and multiplies it by an artificial scaling factor of 1.11 to guess the RMS value. This guess is only accurate for pure sine waves. If you try to measure a distorted square wave or variable speed drive signal with a basic meter, the reading will be up to 40% wrong. A True RMS multimeter uses advanced internal analog computing chips to sample the wave geometry and mathematically solve the Root Mean Square equation in real-time, delivering perfect accuracy on any signal shape.
