The Multimeter is also referred to as a VOM (Volt-Ohm-Milliammeter), and it serves the purpose of a measuring instrument. It is used to combine several functions into one unit, and usually, it measures voltage, current, or resistance.
Their field of application can be very wide since a large number of jobs require measuring of some function or the other. For example, every electrician should own a multimeter because their job is to measure the electric output, and that would seem impossible without a multimeter, or some other similar measuring device.
1. The Fluke 87-V Digital Multimeter
One of the most carefully engineered Fluke products, the Fluke 87-V is absolutely amazing. It comes equipped with a selectable filter so that accurate voltage is always read, the Input alert lets you know when you misplace your input jacks, and the analog graph gives you a clear view of unstable and fast changing signals.
- Easy to use and easy to read;
- Highly accurate;
- Selectable Filter;
- The steep price makes it unavailable to everyone;
2. Fluke 117 Multimeter
This particular Fluke model is intended for the same purpose as all multimeters, but with a crucial difference – it was made to be superior. The True-RMS makes your measurements extremely accurate right on the LED screen. The Fluke 117 was ergonomically designed to be compact in size, so it can be used easily with only one hand. It is terrific to use in any commercial application.
- True RMS – the readings are as accurate as can be;
- LED screen – the Screen is very visible, even when used in darker areas;
- Ergonomically designed size – Compact and easy to use;
- Doesn’t include a Holster
3. Fluke 116 HVAC Multimeter
This Fluke was designed to assist in HVAC application due to its built-in thermometer. It was manufactured with a special feature that aids in prevention against false readings (the “LoZ”), and the large LED light makes it very useful in dim areas.
- Built-in Thermometer – Ideal when HVAC applications are in question;
- Microamps – Testing the flame sensors was never this easy;
- High resistance and frequency;
- It is not quite durable due to its plastic design;
4. Fluke 115 Compact Digital Multimeter
The last of the Fluke family we’re going to review, the Fluke 115 is truly special. Highly reliable, accurate, and available, the Fluke 115 is ideal for frequency and capacitance checks. It can measure 20 A with ease, which can be seen on the standard LED screen.
- Perfect for frequency and capacitance checks;
- Accurate and reliable;
- Very durable;
- Not too versatile;
5. INNOVA 3340 Digital Multimeter
Being different does not necessarily mean that something is better. The Innova 3340 is different and IS better than most measuring devices due to its Automotive design – it is perfect for triangulating any and all engine problems. It includes the temperature probe, auto-ranging, and auto shut-off functions. Very affordable and extremely reliable.
- Temperature probe, RPM clamp, and a case are included;
- Hands-free protection;
- Auto-ranging and auto shut-off functions make it very practical and easy to use.
- It has no NIST certificate
How easy is it to use the multimeter?
Well, it may seem that the multimeter is quite hard to use at first sight, but it is not exactly so. It is outfitted with a lot of buttons, input holes, and a turn-wheel that can be set to several different settings, but the manufacturers knew what people need, so most of them use the standard signs and symbols to represent different measurement categories.
On top of that, every multimeter comes with specific, detailed instructions that describe exactly what function, button, and symbol means. The needs professionals and amateurs are taken into consideration when determining the design and layout of each multimeter, so it’s rather easy to use.
There are many different manufacturers that make different multimeters in the terms of functionality, design, and practicality, while all of them share the same purpose – to make your job of measuring different various categories.
What are the different types of multimeters?
There are two main categories of multimeters – the Analog multimeter category, and the Digital multimeter category, both of which have their advantages and disadvantages if compared. It should be noted that the use of Digital Multimeters is more common nowadays.
The Analog Multimeter is a type of instrument that is a bit simpler if compared to the Digital Multimeter, but it provides accurate readings. The Digital Multimeter can be considered as an improvement of the analog Multimeter, mainly because it offers more functions, and usually, a more detailed screen.
The Advantages of Digital Multimeters
It has the accuracy of a standard measuring device, and has many functions, making it usable by virtually anyone, at any time, allowing for the combination of units to be measured by a single device.
Usually, only a single measuring unit needs to be determined before any other job may take place. For instance, when measuring your electricity at your home you need only see the intensity of your own electric output.
However, if an electrician by trade has the job of determining the electric consummation of an entire residential zone after which he has to compare them, the use of multimeter would prove to be much more efficient than the use of any other measurement device.
The Advantages of Analog Multimeters
- Analog movement – The Analogue meter uses a needle that moves in a continuous motion, giving the accurate readings on order of the magnitudes and trends that often slowly change.
- Availability – The Analogue multimeters are more available in comparison to Digital ones.
The Disadvantages of the Analog Multimeter
- Multiple scales – the multiple scales show many simultaneous readings and often cause confusion. Out of this confusion people commonly make mistakes.
- Inferior input resistance – The use of a Digital meter gives for a higher input impedance.
Knowing this, we should proceed with the main topic – the Digital Multimeters and their advantages:
- Various functions – Digital Multimeters can perform various tasks simultaneously.
- High degree of accuracy – They are as accurate as Analog meters, mainly because of the digitalized screen.
- Simplified methods of use – The Digital meter is very easy to use, and the digital screen provides the exact information which is easy to read.
However, the Digital Multimeters have a few disadvantages in comparison to the Analog ones:
- More expensive – The Digital Multimeters are more expensive and less available in comparison to Analog meters.
- Newer technology – The measuring instruments are being used for quite a while now, and for most people who are accustomed to the older technologies, the methods of Digital meters can be confusing.
