Multimeter Buying Guide For Beginner

You cannot just go to the market and buy any multimeter. Each multimeter is made for a certain cause. Not all are made for your cause. Some are made for commercial use, some are made for home use and some are made for automotive industries. There are many things that you need to keep in mind before buying a multimeter. That is why we have made a buying guide for you so that you can distinguish between multimeters that are for your cause and the multimeters that are not made for your purpose.

True RMS

It is important that your multimeter is a True RMS meter. True RMS refers to true Root Mean Square.  If the machine is True RMS then it would give precise results as it can easily measure varying AC waveforms. Sometimes the waveforms are irregular and sometimes the AC waveforms coming to your homes are regular. So, only a True RMS can measure them accurately. On the other hand, an average multimeter would provide inaccurate results with varying measurements.


You should know for what purpose you are buying a multimeter. If you are planning to buy a multimeter for the automotive industry then your multimeter should be capable of measuring current, and voltage from batteries of old cars.  Your machine should also be equipped with alternator output, tacho check, a clamp, and also RPM checks that are needed for regular and non-distributor ignition systems. On the other hand, if you need a multimeter for homes, the criteria change dramatically. You might not need all the above features for home purposes. So, decide on what purpose you want to buy the multimeter.


It is preferred that you should buy a multimeter that lies between the range of $50 to $100. The multimeter from this price range has all the necessary features. However, if you don’t have financial means then you can go for the multimers that are cheap. Our list contains a few multimers that are cheap but have high-class features. Rest assured, all your requirements will be fulfilled.


Most of the modern multimeters come with auto and manual mode features. Autoranging feature is paramount, nowadays, as it lessens the burden on you. You just have to put in the range and everything will be done by the machine itself.


As a mechanic, you require a machine that provides accurate and precise results with hardly any discrepancies in the final result. However, it depends on many factors such as tolerance level. If the multimeter’s tolerance level is high it will be pretty accurate and precise.
