Some of you may be wondering what those hand-held devices electricians use when troubleshooting wiring systems in your homes and offices are. They are called best multimeters. Best Multimeters have been used in so many applications for many years now. Manufacturers, over the years have developed and redesigned multimeters, adding more features and innovating this device for convenience and versatility. Multimeters are undoubtedly necessary for any type of electrical work- from installing an exhaustfan to changing a circuit panel, multimeters can determine if wires are hot or not.
What are Best Multimeters?
A multimeter, also known as a Volt-Ohm meter is a diagnostic tool used by technicians in both electronic and electrical industry. A multimeter, as the name implies, measures current, voltage, resistance and continuity. There are various applications that multimeters are used for, mainly involving electrical engineering design, diagnostic testing and other applications. These handy, hand-held devices are handy and useful to troubleshoot electrical problems regarding wiring systems, appliances, circuit, motor controls, power supplies, HVAC(Heating, Ventilation, and Air Conditioning) systems, Ham radio applications, mobile repairing,and a lot more.Multimeters are very useful pieces of equipment especially when you know how to use it properly and how to utilize its capabilities, it can distinguish the cause and solve almost all electrical problems, and you can keep your family and your environment safe from electrical hazards.
Types of Multimeters:
There are two types of multimeters- Digital and Analogue. Both Digital and Analogue multimeters share a common factor- they serve as exceptional devices and perfect tools for measuring electrical current, voltage, resistance and capacity. But, how different are these two multimeters? Which is better?
To simply differentiate the two- the type of circuit being used:
An Analogue multimeterunlike a Digital multimeter does not display numbers on the screen, instead, it utilizes a needle or micro ammeter moving over a scale to show the readings. Analogue multimeters are cheaper too, but requires careful handling, accidentally dropping thus type of multimeter may damage the unit. Analogue multimeters are ideal to use in detecting slow voltage changes, as it shows you the micro ammeter moving over the scale. It is the ideal to use when set as an ammeter because of its lower resistance and higher sensitivity, however, when used as a voltmeter, an Analogue multimeter is not as accurate as a Digital multimeter.
Over the years, technology has made innovative changes to multimeters, manufacturers redesigned them and came up with Digital multimeters. A Digital multimeter displays numbers on a digital screen(LCD).And unlike the Analogue multimeter with a needle scale that can be burdensome to read most of the time, Digital multimeters display the test results accurately on LCD screens. This advanced feature is extremely useful as it lets you clearly see and get accurate results instead of guesswork and a rather difficult to read and fluctuating result on a scale. As Digital multimeters are getting more popular and in demand
In terms of functionality and features- several Digital multimeters possess a variety of additional functions a lot of units can test temperature using type K thermocouples, others can measure power levels while others have additional functions like True RMS which amplifies accuracy when testing AC. Data hold freezes result on the screen. And then there’s auto and manual ranging, and a whole lot more.
That said, Digital multimeters, however, since they are in demand and more popular than Analoguemultimeters aredistinctly more expensive.
Different Types Of Digital Multimeters:
The Clamp Digitial Multimeter
This type of Digital multimeter is used to measure electrical flow. The clamp feature of the unit is used for measuring amperage that is flowing through an insulated cablewhile the probes measure the volts. One good feature is its different types of settings- it allows you to choose the setting that is appropriate for what you are measuring.
The most expensive yet the easiest to use among all the types of digital multimeters. The main knob has fewer positions and need to be shifted.
These are multimeters ideal to use for identifying electrical problems and measuring electrical properties in vehicles. Automotive multimeters can come in handy for people who prefer fixing their own cars. These are practical devices to have in your garage as it minimizes the number of meters needed to get separate readings on your cars.
HVAC(Heating, Ventilation, and Air Conditioning)Multimeter
This type of digital multimeter is frequently used by HVAC technicians to diagnose and troubleshoot systems accurately without too much effort.( we have also written about impact wrenches)
How Safe Is it to use best multimeters?
Multimeters are safe to use- mind that each application you use best multimeters for has potential safety hazards that must be taken in carefully when taking electrical measurements. Consulting the included manual before using any electrical test equipment is a must
Categories of best multimeters
There are four categories of multimeters based on their applications- from low risk – CAT I to high risk CAT IV. – Category I is for testing electronic devices, Category II – for testing appliance and domestic loads, Category III – for small-sized industrial circuits and Category IV – for testing power lines and feeds of residential and commercial electrical mains.
Multimeters can measure a variety of quantities- Voltage, alternating and direct, in volts. Current, alternating and direct, in amperes.Resistance in ohms. Some multimeters can measure Capacitance in farads,Conductance in siemens, Decibels, Duty cycle, Frequency in hertz, Inductance in henrys, Temperature in degrees Celsius or Fahrenheit. Digital multimeters may also feature circuits for- Continuity, it beeps when a circuit conducts, Diodes, and transistors.
What to look for when choosing best multimeters:
Choosing the ideal multimeter for you need not be tasking, knowing what you need, what you would use it for and how often you would use it. There is a multitude of different kinds of brands with different useful features. Compare the models and see which features suit your needs.
Suitable for You
Multimeters are used not only by professional electricians, but the DIYers and home owners too. Each user has specific needs- digital multimeters with more advanced features are ideal for a professional electrician or an electronic technician. A commercial electric multimeter would fit a construction worker who has to use it on a regular basis, and for the occasional DIYer, a pocket multimeter would be perfect.
Choose a multimeter constructed from durable materials that could take a few falls and still survive. Multimeters can be sensitive and may stop functioning well if dropped heavily. A well-built multimeter should be tough and sturdy.(we have also written about the best generator brands)
Most electricians and technicians prefer handy multimeters, convenient size that can fit their pockets. You may also choose large sized multimeters with easily readable figures/values.
Look for multimeters that are certified and conforms to the latest safety standards.
If you are opting for a multimeter that has features to make your job easier then you can go for wireless multimeters- these multimeters are ideal and specially designed for engineers, these wireless multimeters feature optimized hardware and software guaranteed to produce accurate measurements andsend measurement data to your phone. Another important feature to look for is a built-in thermometer that would let you take temperature readings without having to use a separate instrument. Multimeters with large display screens and LED backlight are extremely convenient for when you have to work in poorly lit areas. Other features are added useful accessories such as tweezer probes, alligator clipsprobes with banana plugs, needle tip probes, and a temperature probe.
Warranties for each brand and model vary, some manufacturers offer a lifetime warranty, some only provides one-year warrant. A lifetime warranty is ideally, a much better option, as this warranty provides peace of mind and an assurance that you are purchasing a unit that’s guaranteed to last.
Prices vary, depending on the features, brand, model, materials used, accessories included. Some multimeters are significantly pricier than others- well-known brand, packed with features, tried and tested, safe and durable. One thing that’s important to remember is to never compromise safety and durability for the price.
