A multimeter or a multitester , also known as a VOM volt-ohm-milliammeter , is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter can measure voltage , current , and resistance. Analog multimeters use a microammeter with a moving pointer to display readings. Digital multimeters have rendered analog multimeters obsolescent, because they are now lower cost, higher precision, and more physically robust. A multimeter can be a hand-held device useful for basic fault finding and field service work, or a bench instrument which can measure to a very high degree of accuracy.

Multimeter Types and Their Applications

Although basic operational multimeter instruction may be given when the test meter is bought, details of how to use the multimeter to test circuits and gain the maximum use from them are not always available. Although there are major differences between the internal circuits within analogue and digital multimeters, the way in which they are used is comparatively similar. However separate sections are given below with instructions on how to use a digital multimeter and how to use an analogue multimeter. When looking at how to use a digital multimeter, DMM, it is worth understanding the main controls. Normally towards the top of the main front panel is a screen which gives the readings and possibly a few other indications.

Analog vs Digital Multimeter. Multimeter or a multitester is a measurement instrument used in electronics, which is designed to perform tasks of several measuring instruments. The voltage, current, and resistance measurements can be made using different options available in a common Multimeter; therefore, it is also called VOM Volt Ohm meter. In more expensive and advanced models, capacitance and inductance can also be measured and can be used to detect pins of semiconductor elements like transistors and diodes. Analog Multimeter is the older type of the two multimeters, and it is actually an ammeter.

Advantages and Disadvantages of Digital Meters

Most of the engineers, as well as technicians in the electronics field, know the measurement device namely a multimeter. Multimeters are available in different forms in the market based on the characteristics. A multimeter is an essential measurement instrument, used in any engineering workshop or any lab. The main function of this device is to measure the electrical properties of tools as well as wiring in industries. The different electrical parameters in the multimeter can be selected using a dial or a rotary switch on the front side of the instrument. This article discusses an overview of multimeter types. A multimeter is mainly used to measure the three basic electrical characteristics of voltage, current, and resistance.

A Multimeter also referred to as Multitester , is an electronic measuring instrument that combines several measurement functions in one unit. A typical voltage can measure voltage, current and resistance. A digital Multimeter is a test tool used to measure two or more electrical values, principally voltage volts , current amps and resistance ohms. These multimeters are extremely flexible and enable very many faults to be found in an electronic circuit. Digital Multimeters replaced needle-based analog meters due to their ability to measure with greater accuracy, reliability and increased impedance. With ease of incorporating further functionality into an integrated circuit, many digital Multimeters are able to make a number of other measurements such as capacitance; temperature etc and it can also be used to check different electronic devices such as capacitor, transistor and diodes.

Electrical Academia. A multimeter is a device which is used to measure several electrical quantities such as current , voltage , resistance , inductance , capacitance , and electrical frequency. The most significant difference between an analog multimeter and the digital multimeter is that the analog multimeter comprises of a scale and a deflection pointer which actually indicates the value to be measured on the scale, while, in digital multimeters, a digital display like LCD directly displays the value. Routine electrical measurements are usually made with a multimeter. These versatile instruments contain a sensing device, auxiliary circuitry, and switches that allow measuring voltage, current, and resistance in several ranges. Most modern multimeters have an electronic sensing device with a digital display.

Analog or Digital Multimeter

Analogue multimeters have been in use for very many years and sometimes go by the name VOA as a result of the fact that they measure volts, ohms and amps. These multimeters are extremely flexible and enable very many faults to be found in an electronic circuit. Although analogue multimeters are now less common because digital multimeters, or DMMs are now more common, some analogue test meters are still available and may be found in some laboratories or may be available for use at home, etc. The analogue test meters are able to give a good account of themselves and can provide readings that are sufficiently accurate for most purposes.

An analog or digital multimeter is a tool used to measure current, voltage, and resistance. They are very useful instruments that can be utilized in a number of fields, the primary users being electricians. The multimeter is a must-have instrument for any electronic hobbyist, you can identify the problem just by a quick continuity test.

We know that multimeters are basically electronic test equipment, utilized for the purpose of determining various quantities like voltage, current, and resistance, etc. Multimeters are generally classified into two types, analog multimeter, and digital multimeter. The crucial difference between analog and digital multimeter lies in their way of representing the quantity being measured.

Хейл даже замер от неожиданности. - Что. - Я вызываю агентов безопасности. - Нет, коммандер! - вскрикнула Сьюзан.  - Нет.

Двое суток встроенные часы устройств обменивались бесконечными потоками зашифрованной синхронизирующейся информации. АНБ, перехватывая эти информационные импульсы, игнорировало их, считая аномалией сети, безобидной тарабарщиной. Но когда ТРАНСТЕКСТ расшифровал эти потоки информации, аналитики тут же увидели в них синхронизированный через Интернет отсчет времени. Устройства были обнаружены и удалены за целых три часа до намеченного срока взрыва. Сьюзан знала, что без ТРАНСТЕКСТА агентство беспомощно перед современным электронным терроризмом. Она взглянула на работающий монитор. Он по-прежнему показывал время, превышающее пятнадцать часов.

 Ты лжешь. У меня есть доказательство! - Сьюзан встала и подошла к терминалам.  - Помнишь, как ты отключил Следопыта? - спросила она, подойдя к своему терминалу.  - Я снова его запустила. Посмотрим, вернулся ли. Разумеется, на ее экране замигал значок, извещающий о возвращении Следопыта. Сьюзан положила руку на мышку и открыла сообщение, Это решит судьбу Хейла, - подумала .


Digital Multimeter is an electronic device that is used to measure multiple electrical quantities such as current, voltage, resistance, capacitance, impedance and.

The crucial difference between analog and digital multimeter is that an analog multimeter displays the measuring quantity in an analog manner i.e., by a pointer​.
