Analog or Digital Multimeter

Multimeters are tools used to measure current, voltage and resistance. They are very useful instruments that can be utilized in a number of fields, the primary users being electricians. There are two primary types of multimeters, one begin the analog and the other is the digital. The primary difference between the two is the display, an analog multimeter uses a needle to show the value, while a digital multimeter will show the results as numbers on a screen. There are pros and cons to both device, and this article will tackle both these issues.To make measurements on a scale calibration a analog multimeter moves a needle along the scale. These devices are excellent for reading voltage, current, resistance, frequency and signal power. A switched-range analog multimeter can be very affordable, however they can be a bit difficult to use. For users who are new to multimeters may have trouble reading the resistance scale. The analog multimeter also exhibits low resistance and high sensitivity with scales down, which can make it difficult to use. The advantages of using an analog multimeter is when checking a diode the analog is usually more accurate. Other than that, many professionals choose to use a digital multimeter.

As mentioned above, the main difference between a digital and analog multimeter is the display. The digital multimeter displays the reading in digits most times on a LED or LCD screen. This makes taking measurements much more accurate. These tools are often used for measuring voltage because of its higher resistance of 1 M or 10 M.

Overall, digital multimeters are much easier to read and provide more accurate readings. These days many analog multimeters are a thing of the past, and many professionals choose to use digital multimeters. Hopefully this article has explained the difference of the two multimeters and will be helpful when shopping for a multimeter.
