Difference Between Multimeter and Voltage Tester

Whether you want to test a simple circuit you’ve made for your school’s science projection or a faulty apparatus in your home or a wall outlet, at that place are several testing tools that tin can exist used. A voltage tester is probably the simplest of all testing tools used to measure out the menses of electrical current. A multimeter is withal another multipurpose tool that provides a wide range of other electrical testing uses.

What is a Multimeter?

A multimeter is a standard diagnostic and troubleshooting tool for technicians in the electrical/ electronic industries. It is a handheld testing device used to measure 2 or more electrical values, principally voltage (volts), current (amps), and resistance (ohms). It is likewise a common household testing tool used to cheque faulty appliances for some defects in their electrical circuits or components. Information technology looks for electric resistance within a circuit, just can be used to bank check multiple electrical properties. About all multimeters can measure voltage, current, and resistance.

More than advanced multimeters might have other functions, such every bit the power to measure other values like capacitance, transistor gain, or diode forrard voltage. Multimeters tin be analog or digital. Analog multimeters use a needle along a calibration to test electrical instruments, whereas digital multimeters utilize an LCD to direct display the value. There’s however some other blazon of multimeter called motorcar-ranging blazon which, every bit the proper noun suggests, sets the exam range automatically. You have to spend some extra bucks for the auto-ranging blazon though.

What is a Voltage Tester?

A voltage tester, also known more than commonly as voltage detector, is a simple electrical testing tool that checks for presence or absence of an electric charge in an electric circuit or component. It is mainly a pen-shaped testing musical instrument used for electrical power testing uses. The device detects the electric field generated by voltage on a wire or other electrical system to cheque if the wire or a arrangement is energized with an electrical potential. Information technology can be an piece of cake-to-use hardware that detects the presence of electricity or a more than advanced tool to discover precise voltage levels in an electric system.

A non-contact voltage tester is besides used to quickly verifying that a circuit is energized or deenergized. However, it should non replace voltmeter testing to prove that a circuit is deenergized for safety reasons. Non-contact voltage testers are relatively small, battery-powered devices that easily fit in your pockets. They typically have an on/off button, a flashlight or indicator, a high-intensity LED lite, a bombardment indicator, and a built-in self-test feature. These are also available in several voltage ranges. However, these are not meant for sensing the presence of DC voltage.

Deviation between Multimeter and Voltage Tester


 – A multimeter is a multi-purpose electrical testing tool used to measure two or more electric values, principally voltage (volts), current (amps), and resistance (ohms). It also functions as a voltmeter, ammeter and ohmmeter. Near, all multimeters tin measure voltage, current and resistance. A voltage tester is a simple electrical testing tool used to detect the presence or absence of an electric accuse in an electrical circuit or component.


– A multimeter looks for very low resistance to come across if two points are connected. Information technology does that by injecting a small current into the excursion and then taking a reading of the voltage drop across those points in the electric circuit. The voltage drib is then used to summate the resistance. A simple neon voltage tester has two wire leads with a metal probe on each end. The wire probes need to be in contact with the wires; one probe touches the hot wire and the other ane goes to neutral. If in that location is current present, the neon bulb volition calorie-free upward.

– A multimeter has to be connected in series within the circuit, which means you need to break the circuit beginning. Information technology is a relatively lengthy procedure and requires proper handling. It can be a bit risky to operate, if not handled by professional electricians. A voltage tester, peculiarly a not-contact voltage tester, is a simple, battery-powered voltage testing tool that is the easiest and the safest to use. Information technology allows yous to check for voltage without having to bear upon any wires or parts in a circuit.

Multimeter vs. Voltage Tester: Comparing Chart


There are a lot of different types of testers that the electricians use for diverse different purposes. Not-contact voltage testers are probably the easiest and safest to utilise testing tools that detect the presence of voltage in a circuit without you having to impact whatsoever wires. However, these are non accurate at all the times and sometimes, they show false readings. Multimeters are multipurpose testing tools that can be used to measure two or more than electrical values, principally voltage (volts), current (amps), and resistance (ohms).

What is the divergence betwixt a voltage tester and a voltmeter?

If you need to measure out voltage, so a voltmeter is sufficient. A voltmeter is used to measure the potential difference (or voltage) between two points in electrical circuits. A voltage tester is a simple tool used to detect the presence of electricity in a piece of electrical equipment.

What is a voltage tester used for?

A voltage tester is a simple handheld testing tool used for electrical power testing uses.

Can you employ a multimeter as a voltmeter?

Yes. A multimeter is a multipurpose testing tool that also functions as a voltmeter, ammeter and ohmmeter.
