How to Buy the Best Multimeter

How to Buy the Best Multimeter

A multimeter is a complex device that needs detailed understanding if you want to use it correctly. You also need some of this understanding to buy the right meter.

Following is a listing of the most important aspects and features of a multimeter that you need to understand and keep in mind when making your choice.

#1. Digital vs Analog Multimeters

The first major difference between multimeters is their fundamental working system and this creates two groups, namely: Analog and digital multimeters.

Analog Multimeters. This type of multimeters uses classic analog dials to display measurement readings. They also use a traditional (analog) electronic circuit to calculate the measurements and complete other tasks.

Multimeters were originally analog before digital systems came around, but many users still prefer analog multimeters because they often have very high sensitivities and reaction time to the slightest changes in their measurement.

Digital Multimeters. A digital multimeter uses both a digital circuit and an LCD display, setting it apart from analog multimeters. In addition to being easier to produce, digital multimeters offer much more functions and possibilities than analog meters.

Some of these functions include Auto-range adjustments for convenience, oscilloscope function to record readings over time, a Hold function to keep the display from changing when taking readings, and large-digit displays with back-light for ease of use.

#2. Auto vs Manual Range

Ranging is the process of pre-selecting a result range for either the capacitance, resistance, or voltage that you're measuring. This developed as a result of limitations in electronic components, but with digital multimeters, you can get done automatically.

With analog meters, you'll always have to select the correct range before measuring. This way, you'll know if you're calculating your capacitance results in nano- or micro-farads, for instance. If you've got a digital multimeter, however, and it offers auto-ranging, then the system does the choosing for you automatically.

Keep in mind, however, that auto-ranging is only limited to the range of your multimeter. So if your meter's voltage range is 600 Volts, for instance, auto-range can get you past that 600-Volt limit.

#3. Accuracy & Resolution

If you want accuracy, then a good quality digital multimeter will be your best option. Be mindful though, that most cheap digital multimeters are less precise than the costlier ones, so, you'll need to pay a little more for higher accuracy.

With resolution, the number of digits that a digital multimeter can display comes into play. You'll mostly see meters with either a 3.5 resolution which has a top value of 1999 or a 4.5 resolution with a 19999 top value.

Another method of showing a multimeter's accuracy is with counts, where you can see 2000 counts and higher. Here, the counts refer to how many figures the meter can display before it reaches the next range level.

#4. Durability & Warranty

A better-built multimeter using better materials will serve you better and last longer. So, it's often worth the extra price you pay for it, but you need to make sure that it comes with an appropriate warranty.

The terms and duration of a warranty often show how much faith a manufacturer has in its products, which in turn reflects how many quality materials and engineering that it invested in it. On average, however, products with longer warranties come at a higher price.

#5. Ease of Use

A good multimeter should be easy to understand and to work with. You should easily figure out how to select your variables and where to plug what in by simply looking at it.

Its batteries and changing or recharging options are also worth considering, as well as a back-light if you'll be working in the night or in dimly lit areas.

Further ease of use features for digital multimeters includes an auto-ranging function and an auto-off feature to help maximize battery life.

#6. Price & Warranty

Multimeters cost anywhere from $10 to well over a thousand dollars and these costlier models obviously come with more advanced modules and features than the cheaper varieties.

How much you finally choose to invest is up to you, just make sure that you keep an eye on the warranty terms, especially when going for costlier models.


We have reached the end of this multimeters review and you've seen all the different meters from different manufacturers, including the affordable and the top of the line, expensive ones.

As you can see, there's a wide range to choose from and this depends on your needs and on how much you're willing to spend.

The final decision, therefore, is yours alone to make. Choose a multimeter that meets your needs and fits into your lifestyle.
