Features and Considerations in Electronic Multimeters

When ​looking at multimeter reviews for electronics technicians, there are some things you should check. Different multimeter features will be more important depending on the types of jobs you will be performing. Here are the most important features to look for that will help you choose the right device for yourself.

Safety

Multimeters are assigned different CAT ratings to determine whether you can use the device safely. Voltage spikes are a constant possibility for electronics technicians, especially in circumstances like an electrical storm. If you are in an area with unpredictable weather, be sure to purchase a multimeter that is able to deal with high transient impulses.

Here’s a brief guide:

  • CAT I Multimeter: It is best used in 24 voltage circuits and can only be used in circuits if it is not connected to a power supply. It’s usually used for testing in small electronics with a source based on high-voltage and low-energy.
  • CAT II Multimeter: You can use this multimeter on plugged-in electronics so long as it is below a 100A circuit. It should be below 22,000 voltages and on circuits between 110 voltages and 240 voltages. It is perfect for appliance testing, home power tools, and household outlets further than 10 meters from the breaker.
  • CAT III Multimeter: This is an all-round multimeter you can use for various applications before the main breaker, such as large appliance outlets. Polyphase or switchgear motors can be safely tested. It is often used to test commercial lighting and small industrial light fixtures like single-phase commercial lighting.
  • CAT IV Multimeter: This is used to test main feeds in power lines (including pole to building), commercial structures, and residences. You can use this type of multimeter with a direct power source.

Auto or Manual Ranging

A multimeter can determine the range you are testing when it is in auto range mode. Set the meter up, and it will output the desired measurement. The mode saves you time because you do not have to input the range.

That saves you time as you do not need to know the voltage, capacitance, resistance, and other values.

With a manual range, you’ll have to input the values which require a lot of time, and knowledge of the electronics you are testing. However, experienced electricians may prefer these types of multimeters if they’re sure about the measurements. 

Poorly constructed multimeters with auto ranging enabled can often be unpredictable, and at worst unsafe. When looking for a budget multimeter, it may be a better idea to look for one that has a manual range option. Auto range, when incorrectly implemented, can cause an incorrect diagnosis or setting.

Digital or Analog

This is the most crucial decision you will have to make. Analog multimeters have lower input impedance compared to digital multimeters. Impedance indicates the sensitivity of the current that is being measured.

The meter can take measurements of any voltage if the input impedance is high. Analog multimeters are also limited to reading voltages, amps, and electrical resistance. Experienced electricians who are looking for a range sometimes find that a needle pointing to the area they are expecting makes their work easier.

On the other hand, digital multimeters go beyond these three measurements. They also come with numerous features and provide numeric readings that appear on an LCD screen. In addition, digital multimeters offer a higher possibility of accuracy since you can read the exact measurement in print.

Resolution

You should choose a multimeter from a brand that is known to offer quality resolution. The device should also be able to detect a change in the input signals that may trigger changes in the overall output signal.

The resolution, also known as the count, is shown through the numbers that appear on display for digital multimeters. Most of the models available are either 3.5 or 4.5 digits meters with a 1999 to 19999 range.

Whether you need the device for personal or professional use, you need to select a meter that’s reliable when handling more sensitive jobs and provides excellent resolution. Note that the resolution will be good if the range of the multimeter is wide. 

True RMS

This is an important feature to think about when looking for a multimeter. It is responsible for measuring AC voltage. The feature will enable you to evaluate the effectiveness of the AC wave signal.

A device with an average level of response utilizes mathematical formulas when taking accurate measurements on sinusoidal waves. While you may be able to make non-sinusoidal waves, the multimeter may lack accuracy.

However, the most sophisticated meters are capable of providing precise measurements both in sinusoidal and non-sinusoidal waves. Any attempt to measure the distorted waves maybe 10% high or 40% during calculations.

Voltage Range

Capacity and voltage range of a multimeter depends on how and where it will be used. For instance, the needs of someone that works in an industrial complex will be different from those of a homeowner.

The good thing is that the majority of meters can work with main power sources, megavolts, and more. A multimeter with a wide voltage range is ideal for an electrician. Each multimeter should have an obvious voltage range displayed.

Depending on the application you are using the multimeter for, a voltage range may not give you adequate information. Check the CAT rating, since impedance spikes might occur that are outside of the voltage rating.

Size

Multimeters come in different designs and sizes. When choosing a meter to suit the type of work you do, it is essential to pick one with the right size to make your work easier. Some multimeters are small in size while others are big.

Ensure you select one that is easy to handle and compact. If your job involves a lot of fieldwork, a compact multimeter with a sturdy design is the most desirable device to have.

Functions

There are different multimeters available in the market with various features. Therefore, you should check the functions that you need before buying a multimeter. For instance, ask yourself whether you need a thermometer, AC, or DC voltage.

Additional advanced features that come in handy are a graphic display with real-time data, data logging to keep track of aberrations, and the most important, ohm measurement.

Check the most crucial functions you need then buy a multimeter with those functions. It can also be a good idea to get a multimeter with fewer functions. This will make it easier to use the multimeter.

Construction and Design

This is an essential aspect of a meter. It can fall off during its operation at some stage or fall from the bag. For this reason, selecting a rugged design that may take up all the abuse is very important. Some multimeters are not good at this and may break after falling.

You should choose the most rigid and well-built device that can face up to all the heavy usage. Also, in case of human error, the meter should not become a paperweight. This will ensure you have a long-lasting multimeter.

Price

You should look at price as the deciding factor when shopping for a multimeter. However, the first aspect you should look at is whether the device is good enough for the projects you intend to do.

Basic and easy meters come at a small price while the advanced ones are more costly. Choose a multimeter that is affordable with the features you need.

Accuracy

Accuracy of a multimeter is another crucial function you should check. Not all multimeter devices offer high accuracy. Before you choose one, ensure it gives accurate results. Accuracy will also depend on the type of circuits you usually work on.

Temperature Sensor

This feature is used to determine the temperature and is useful when working on components that are sensitive to temperature. As such, the meter you intend to buy should have this function.

Warranty

Like the price, warranty is also important. A multimeter that comes with warranty gives some sense of responsibility the manufacturer holds. Sometimes, meters do not function properly or come damaged. In such scenarios, the warranty becomes essential.
