Factors for Buying a Digital Multimeter

What is the Advantage of a Digital Multimeter Over the Analog Ones?

Digital multimeters come with more accuracy and eliminate the hectic reading process. You get everything within the blink of an eye within its screen. The standard digital multimeters have an accuracy of 0.5% on DC Voltage, while this is 0.01% in the case of benchmark ones.

What Should I Look for Before Buying a Multimeter?
  • The accuracy of the device and the parameters it can measure. It includes the voltage, current, and resistance, temperature, transistor check, etc.
  • The range of these parameters and measuring capabilities (Min-Max range support for each parameter).
  • The size and backlit supported LCD will help to work in a low light environment.
  • TRMS values and their abilities to read AC parameters for professionals.
  • Weatherproof standards. See if they come with the CAT III rating.
  • Build quality, portability, and Auto-shut off to save battery
Should You Consider a TRMS or a Non-TRMS Multimeter?

The True RMS is applicable in the case of AC parameters. The Fluctuating AC makes it hard to get an accurate reading and hence the root mean square value is more useful.

It can calculate the values of both the sinusoidal and the non-sinusoidal AC (like square) waveforms. If you are developing something or working or hardware design, you must have a TRMS meter. For home use, you don’t need to pay for the TRMS feature.

What is Auto-Ranging?

The Auto Ranging on the multimeter lets it adjust its own internal range to find the correct current and voltage values. Auto-ranging can be very helpful if you are a newbie in electrical and you have no idea how much voltage you are going to measure. These Auto-Ranging multimeters are more reliable than the other ones.

You can have decent multiple meters below 50 bucks from Amazon for home use. However, if you are a professional and you work with non-standard ac voltages and other parameters,s better to invest in expensive TRMS multimeters for high accuracy.
