Rating of the best voltmeters for 2020

Voltmeter - a device that determines the voltage and electromotive force (EMF) in electrical circuits. Here is a list of the best voltmeters for 2020, which will help you make the right choice.

General information about voltmeters: their classification, selection criteria for devices

The table provides general information about the categories of voltmeters, which are characterized by 3 main features.

Table - "Classification of voltmeters"

By working system (class of belonging):	By type of destination:	By way of operation:
Electromechanical:	with constant current;	panel board;
· Magnetoelectric (M);	with alternating current;	portable;
· Electromagnetic (E);	pulse;	stationary
· Electrodynamic (D);	phase-sensitive;
· Electrostatic (C);	selective;
· Rectifier (C);	universal
· Thermoelectric (T).
Electronic:
· Analog;
Digital

An important category that requires a thorough study is the purpose of devices. Knowing the structure of the structure and the principle of its operation, the buyer will not make a mistake when choosing a voltmeter.

Table "Structure and operation of voltmeters"

Name (abbreviation):	Purpose:	Operating principle:	Using:
With constant current (B2):	measure voltage in networks with direct current	has polarity, therefore requires strict observance when connecting: "+" - to the upper point of the potential, "-" - to the lower point	at home
AC (V3):	measure sinusoidal voltage with a frequency close to 50 Hertz	has no polarity, therefore it is connected in parallel to the load for which the voltage is measured	-
Pulse (B4):	measure the amplitudes of periodic signals with high duty cycle and single pulses	-	for verification and certification of radio measuring equipment
Phase-sensitive (B5):	measure the quadrature components of the complex voltages of the first harmonic	makes it possible to determine the complex voltage, taking as zero the initial phase of a certain reference voltage	to study the amplitude-phase characteristics of two-port networks (amplifiers, for example)
Selective (B6):	to isolate certain harmonic components of complex signals and the rms value of their voltage	selects certain harmonic signal elements or a narrow frequency band using a tunable filter; measures the current value of the selected signals	as a measuring receiver
Universal (B7):	measurement of direct and alternating currents	-	at home

The article will focus on electronic voltmeters. This type is used for diagnosing household wiring, car electrical systems and repairing various household electrical appliances. It is widely used in the construction industry. What to look for when choosing a voltmeter? Key recommendations:

• range of measured voltages: it is advisable to choose a device with a certain margin for the level of measured values;
• capabilities: many devices are equipped with various functions (for example, measuring the parameters of an alternating current sinusoid) that are not needed for the home;
• for household purposes, it is better to purchase a universal voltmeter;
• the value for money depends on the protective properties of the case;
• it is better to use a digital built-in DC voltmeter to monitor the voltage in the vehicle network.

The greater the internal resistance in the device, the better it makes measurements.
