Wondering what is a multimeter? A multimeter is simply an electronic tool which is used for measuring resistance, voltage and continuity. The multimeter tool also measures the presence of AC or Alternating Current and DC or digital current in the circuits. A multimeter is also termed as Volt-Ohm meter, which may be categorised into digital multimeters and analog multimeters. Each of the multimeters has their unique applications and features.
What is an analog multimeter?
An analog multimeter is designed as a micrometer whose needle moves long the scale calibration in order to make various measurements. You can buy switched range multimeters for they are cost-effective, but then they are not so user-friendly. Apart from this, reading the resistance scales on analog multimeter is critical, to some extent, and cannot be used efficiently by those who lack experience. You can use the analog multimeter as an ammeter as this multimeter shows incredibly lower resistance and great sensitivity. Measuring voltage with the device is far more convenient when you use analog multimeter for you can easily track the slowly changing voltage by observing the multimeter needle. The multimeter movement is too much delicate, and hence, you need to handle it with great care to avoid potential damage.
What are digital multimeters?
Digital multimeter depicts digits, typically. Some of the digital multimeter may also depict crystal liquid display bar that represents the measured quantity. It acts as a superb tool for measuring voltage, and it is the most preferred voltmeter as it has far higher resistance, ranging around 1M-10M in contrast to analog multimerer that has 200. For obtaining accurate readings, the resistance of digital multimeters must at least be ten times the circuit’s resistance. You can easily rely upon digital multimeters for they are better performing multimeters when compared to their counterparts. Some of the best mutimeter in the market are digital multimeters. They are far more accurate and more convenient to use although they may be a bit expensive. Even the most basic and simple digital multimeter is equipped with a greater number of features than its counterparts. Such a multimeter has great applications such as frequency meters, temperature sensors, and capacitance meters.
The industry of multimeters…
There has been a great rise in the demand for multimeter and this has led to the development of specific multimeters with some special features. For example, it is crucial for automotive engineers and electrical engineers to invest on special categories of multimeters. Special multimeters can meet the measurement requirements of electrical and automotive engineers. There are automotive digital multimeters that have found great usage among the electronic engineers. In case of general multimeters, you cannot expect to get the same precision which you get in automotive digital multimeters. General multimeters are meant for hobbyists who indulge in hobby electronics. It is highly advisable to read through the multimeter reviews before making a purchase.
If you talk of precision and accuracy, then it is digital multimeters that are the most versatile equipment. They are the most reliable temperature calculating tools that you may get on the market. It has great applications in various sectors such as food services, construction areas, heating applications and a number of industrial applications. Digital multimeters are replacing analog multimeters. Digital multimeters provide best solutions to production managers and engineers, who are involved in technical work in electronic industries.
