Product Description

 Digital Multimeter Tester Volt Ohm Meter Electrical Testers and Multimeters DMM DVM
 

A digital multimeter (DMM), also known as a digital voltmeter (DVM), is an electronic instrument used to measure electrical quantities such as voltage, current, and resistance. It combines several functions into one device, making it a versatile and useful tool for electrical and electronics engineers, electricians, and technicians.

A typical DMM consists of a display screen, a dial or buttons to select the measurement function, and two probes to connect to the device under test. The device can be used to measure voltage in both AC and DC circuits, current in both AC and DC circuits, resistance, continuity (to test whether a circuit is open or closed), diode testing, and capacitance, among other functions.

In addition to the basic measurement functions, some DMMs also have advanced features like temperature measurement, frequency measurement, and data logging. They may also have a range of safety features like overload protection and fused current inputs to protect the user and the device under test.

DMMs can be analog or digital, but digital multimeters are more common today due to their high accuracy, ease of use, and advanced features. They are widely used in a variety of applications, including troubleshooting and maintenance of electrical and electronic systems, quality control, and research and development.

Product Characteristics

UT61 series digital multimeter is characterized by high reliability, high safety, automatic range, handheld multimeter and so on. With large screen digital and high-resolution analog pointer synchronous display function, full-range overload protection and unique appearance design, making it a new generation of practical electrical measurement instruments with more excellent performance. It also has RS-232 or USB standard data transmission interface, data hold, relative measurement, peak measurement, under-voltage indication, backlight and automatic power-off function.

Analog and digital multimeters are both used to measure electrical quantities such as voltage, current, and resistance, but they differ in their display, measurement accuracy, and additional features. Here are the main differences between analog and digital multimeters:

Display:

Analog multimeter: It uses a dial with a needle or pointer to display the measured values. The scale is printed on a dial, and the position of the needle indicates the value.
Digital multimeter: It has a numeric, usually LCD, display that shows the precise measured value in digits. It provides a digital representation of the measured quantity.

Measurement Accuracy:

Analog multimeter: These devices have a limited accuracy, usually specified in terms of a percentage of full-scale reading or in number of divisions on the scale.
Digital multimeter: They offer higher accuracy and resolution. The accuracy is usually given as a percentage of the reading plus a number of least significant digits.

Measurement Speed:

Analog multimeter: The needle movement on an analog meter takes some time to settle, which may require the user to wait for a stable reading.
Digital multimeter: They provide faster measurements as the readings are displayed instantly on the digital screen.

Additional Features:

Analog multimeter: Typically, analog multimeters have fewer additional features. They may include a few basic functions like testing diodes, continuity, and measuring resistance, voltage, and current.
Digital multimeter: Digital models often come with a wider range of features such as true RMS measurements, data logging, capacitance measurement, frequency measurement, and temperature measurement. They may also have auto-ranging capabilities and be able to measure higher voltage and current ranges.

Digital multimeters are more commonly used today due to their higher accuracy and additional features. However, analog multimeters can still be useful in certain situations, especially for quick measurements or when a digital display is not required.
