How to Choose the Best Multimeter
A. Basic Features
A basic multimeter can measure AC/DC storage, AC/DC current, resistance, continuity, and diodes. At the very least, these are the things that the multimeter you will buy should be able to read.
The multimeter you should buy must have a higher main voltage rating than what is used to operate household appliances that you intend to test.
In terms of resistance and continuity measurement, the multitester you should buy should indicate small resistance either through beeps or visual alerts. What’s important is that the alert doesn’t delay.
Lastly, the digital multimeter should have a diode check function displaying the forward voltage drop of the diode.
B. Advanced Features
There are also advanced features that may affect your buying decision. However, you should know what these features are and if they are of relevance to you.
For one, a multitester with graphic functions is a good buy as it can display the AC measurements in real time. This is a very good feature especially if you are looking for irregularities.
Another advanced feature that you may be interested in is data logging. It lets you monitor and document measured data over a long time frame.
Other advanced features that you may want in a multitester are low pass filter which comes in handy when troubleshooting motor drives, and low impedance mode to prevent induced voltages from the measurement.
There are two types of multimeters--- digital and analog.
Digital multimeters use digital circuits, measuring current in discrete currents. Digital meters are considered the more accurate of the two types of multitesters.
These are accurate up to within half of a percent. The lower the number of accuracy, the more precise the multimeter is in measuring current.
There are three types of digital multitesters—fluke digital, clamp digital, and autoranging multimeter. Fluke digital has different calibration functions while clamp digital is used for measuring the flow of electricity. Auto ranging multitester is the simplest to use among the three.
Analog multimeters may be cheaper than digital multitesters but these are also a lot more difficult to read. You should be a skilled electrician in order to properly use this type of multimeter.
- Price—multimeters aren’t really expensive. You can get one for as low as $20. But don't just buy the cheapest. Consider the features, too, and whether or not you need them.
- Brands—usually, the multitesters from reputable brands are more reliable compared to those from virtually unknown manufacturers. Some of the brands that you can trust when it comes to multitesters are Fluke, Klein, Beckman, HP, Extech, Aligent and Wavetek.
- Safety certifications— most reputable brands like Fluke also have get safety certifications from independent, third-party testing agencies.
Shopping for a multimeter or multitester can be really intimidating especially with all the functions that this device typically has. But you should not be frightened at all because these are very handy and easy to use tools that you will find practical at home.
Whether you are checking appliances, wall outlets, or even working on your vehicle, a multimeter can be a very handy tool to have.
Just remember the various features that a good multimeter should have, such as AC/DC storage, AC/DC current, resistance, continuity, and diodes. Advanced features like data logging and graphic functions will also make it easier to use the tool.
