Voltage Tester

What is a voltmeter?

A voltmeter is an electrical measuring instrument used to measure electrical voltage in an electrical circuit. It is an essential part of electronic equipment and is used by electricians, electronics engineers, and other professionals. A voltmeter measures the voltage difference between two points in an electrical circuit and displays the result in volts (V) on a scale or a screen. The voltmeter is designed to have a high input resistance, which means it draws minimal current from the circuit while measuring the voltage, so it does not affect the circuit it is measuring.

There are different types of voltmeters, including analog and digital voltmeters. Analog voltmeters display the voltage level using a needle that moves across a scale, while digital voltmeters display the voltage level numerically on a screen. Digital voltmeters are usually more accurate and easier to read than analog voltmeters.

Voltmeters can be used to test and measure voltage levels in various electrical circuits and components, such as batteries, wires, outlets, and electronic devices. Voltmeters can also be used to diagnose electrical problems and troubleshoot.

The benefits of using a voltmeter

• Measuring voltage: The voltmeter can measure the voltage across a given part of a circuit, and this can help determine whether the voltage is sufficient for the task.
• Identifying faulty components: The voltmeter can help you detect faulty components in a circuit by measuring the voltage across individual components. If the voltage is uneven, or if there is no voltage at all, it may indicate a faulty component.
• Troubleshooting: The voltmeter can be used to troubleshoot problems in a circuit, especially when combined with other measuring instruments such as an ammeter. By measuring both voltage and current, it can provide a better understanding of where the problem lies - and this can be a great help for you.
• Monitoring: You can also use the voltmeter to monitor the voltage of a battery, and this can tell you whether the battery is in good condition or needs to be replaced.

Overall, a voltmeter can help ensure that an electrical circuit is functioning correctly and that any problems can be identified and resolved quickly and efficiently.

Different electrical measuring instruments for your needs

Voltmeter or ammeter? There is, of course, a difference between whether you need to see if there is voltage through the circuit or if your need is to measure whether high current is being conducted correctly through a wire; we have a voltage tester for every purpose.

Our voltmeters are produced by German testo, which has over 60 years of experience in producing professional measuring equipment for electricians and other industries, ensuring you consistent high quality every time you purchase new measuring equipment from Testo. It is important to have a basic knowledge of electrical circuits and measuring techniques to use a voltmeter correctly and achieve accurate results. If you are not familiar with using a voltmeter, it is recommended to seek help from a professional electrician or technician.

Voltmeters and ammeters

Voltmeters and ammeters are two different types of measuring instruments used to measure electrical parameters in an electrical circuit. A voltmeter measures electrical voltage between two points in the circuit, while an ammeter measures electrical current flowing through a component or a wire. A voltmeter operates by connecting the instrument in parallel with the part of the circuit where the voltage is to be measured. When the voltmeter is connected correctly, it will measure the electrical voltage between the two points in the circuit and display the result on a scale or a screen. An ammeter works a bit differently. The ammeter must be connected to the part of the circuit where the current is to be measured. When current flows through the ammeter, it will measure the current and display the result on a scale or a screen. Voltmeters and ammeters can be analog or digital. Analog measuring instruments use a needle and a scale to display the result, while digital measuring instruments display the result numerically on a screen. Digital measuring instruments are usually more accurate and easier to read than analog measuring instruments.

The two last electrical measuring instruments that are most well-known are the polarity tester and clamp ammeter.

Digital multimeters

A multimeter, also called a universal instrument, is used when you want to measure several different electrical phenomena such as current, voltage, frequency, and resistance with the same measuring equipment. They are more versatile than single-function measuring instruments, such as voltmeters or ammeters, and are therefore a popular device among electronics and electrical engineers. Digital multimeters use a range of advanced technologies and features, such as a high-resolution screen that can display measurement values and graphical representations, and an automated range and area selection that allows measuring a wide range of electrical values without having to adjust the device manually. Additionally, digital multimeters are usually more accurate than analog multimeters.

Digital multimeters can also have other advanced features, such as data hold, temperature measurement, diode testing, continuity testing, and much more. These features can be useful for troubleshooting and diagnostics in electrical circuits and can help you find and fix faults quickly and efficiently. Digital multimeters are portable and lightweight, making them easy to use and transport.

We only sell digital multimeters with an AD converter that converts the measurements into numbers displayed on the screen. Earlier multimeters were referred to as moving coil instruments.

Polarity tester and clamp ammeter

A polarity tester is used to find out which wire is live, as well as whether there is current in a given wire. A clamp ammeter is a measuring instrument used to measure the current flowing through a wire or a component without having to break the circuit. The clamp ammeter works by clamping the jaws around the wire or component and measuring the current flowing through it.

You can greatly benefit from using a clamp ammeter in measurement cabinets with tight or no space; you simply place the clamp on the wire to be measured and read the display.

Saveris current rectifier

The last category is the 1-channel testo Saveris U1 E Ethernet sensor / analog coupler, which enables the recording of other measurement parameters in the testo Saveris monitoring system by integrating all transmitters with standardized current/voltage interfaces.

Why choose a voltage tester?

The two most important characteristics of electricity are voltage and current. To measure this, we have voltmeters, that is, voltage testers, and ammeters. A voltmeter measures the voltage between two points, while the ammeter measures the current through them. Additionally, there are multimeters that can measure both current and voltage at the same time.

A multimeter is therefore also often referred to as a universal instrument. It is used when you want to measure several different electrical phenomena such as current, voltage, and resistance with the same measuring equipment. We only sell digital multimeters with an AD converter that converts the measurements into numbers displayed on the screen. Multimeters have also previously been called moving coil instruments. Furthermore, there are several electrical measuring instruments, but the most well-known are:

• Polarity testers
• Clamp ammeters

A polarity tester is used to find out which wire is live, as well as whether there is current in a given wire. A clamp ammeter is used to measure voltage in a wire without having to cut the wire and strip it. You can greatly benefit from using a clamp ammeter in measurement cabinets with tight or no space; you simply place the clamp on the wire to be measured and read the display. It cannot be easier to measure current.
