Voltage meeter
They are widely used to measure the value of electrical quantities such as voltage, current, resistance, etc. Multimeters are widely used in electrical testing and troubleshooting. The cost is of a voltage tester is comparatively low. Multimeters are costlier than a voltage tester.
neon voltage tester, digit voltage tester, non-contact voltage tester, etc. The voltage testers are of following types viz. analog multimeter and digital multimeter. The voltage tester is compact in size and is of pen-shaped.īased on the design and method of measurement and display, the multimeters are of two types viz. The design and construction of a multimeter is complex as it composes multiple instruments.Ī multimeter is relatively bigger in size and shaped as a palmtop (handheld). Voltage tester only detects the presence and absence of electric charge and does not provide its value. Multimeter provides the value of measurement in the standard units. If there is electricity (or current) present in the circuit, the neon bulb will glow. These metal probes are connected in the circuit, where one probe touches the live wire and the other probe goes to the neutral. When these two probes are connected in a circuit, the multimeter injects a small current into the circuit and then taking reading of the measured quantity.Ī voltage tester also has two leads with a metal probe on each end. ParameterĪ multimeter is a standard measuring instrument that is used for measuring multiple electrical quantities in an electric circuit.Ī voltage tester is a simple electrical testing instrument which is used to check the presence and absence of the electric charge or electric potential in an electric circuit.Ī single multimeter can function as a voltmeter, ammeter, ohmmeter, frequency meter, etc.Ī voltage tester functions only as a detector for electricity in an electric circuit or component.Ī multimeter has two leads with a metal probe on each end. The following table shows the key differences between multimeter and voltage tester. Difference between Multimeter and Voltage Tester If it does not glow, then there is a trouble at this point. If the wire or component is receiving electricity, the neon bulb will glow. In order to use a voltage tester, one probe is attached to the wire and the other probe goes to the neutral. The voltage tester can also be used to test whether adequate voltage is present in a wire. Each wire ends in a test probe made of metal.Ī voltage tester is always used with the current turn-on to test whether there is current flowing through a wire and to test for proper grounding. A typical voltage tester consists of a small neon bulb with two insulated wires attached to the bottom of the bulb housing. Basically, it is a pen shaped testing device. The voltage tester is also known as voltage detector.
What is Voltage Tester?Ī voltage tester is a simple electrical testing instrument which is used to check the presence and absence of the electric charge or electric potential in an electric circuit. Thus, one can choose an instrument based upon the requirements. In a digital multimeter, the measured value of the quantity is displayed on a digital screen.īoth analog and digital multimeters have their own advantages. The analog multimeters are mainly used to measure electrical quantities like voltage, current, resistance, frequency and power, etc.Ī digital multimeter (DMM) is a measuring device which can also be used to measure electrical quantities such as voltage, current and resistance.
It consists of a display of analog form that uses the deflection of a pointer to indicate the level of the measurement. Types of Multimetersīased on the design and method of measurement and display, multimeters are classified into two types as −Īn analog multimeter is the type of multimeter based around the use of a moving coil meter. The multimeter is one of the important measuring instrument which is preferred by electricians for troubleshooting the problems in electrical appliances, motors, circuits, etc. With a typical multimeter, one can measure AC voltage and current, DC voltage and current, resistance, continuity, and other values.īasically, a multimeter is a combination of a DC voltmeter, AC voltmeter, DC ammeter, AC ammeter and ohmmeter. Go through this article to get a basic understanding of how multimeters and voltage testers work and how exactly they are different from each other.Ī multimeter is a standard measuring instrument that is used for measuring multiple electrical quantities in an electric circuit. Multimeters and voltage testers are both testing and measuring devices that are used to measure a wide range of electrical quantities.
