Best Automotive Multimeter Buyers Guide

A general question may come into your mind that why getting a separate multimeter for automotive use if already have one in your tools kit. Answer is simple you can,t open all screws from same size of wrench. You must have a right tool for a right job, in simple words automotive applications demand a sensitive multimeter with relatively lower impedance. Low impedance make sures that meter will not effect any circuit or device performance when applied to it.

Now you don,t have to worry for honest selection of best automotive multimeter. If you are not satisfied after reading above reviews you should must read this buying guide which can resolve all your queries related to automotive digital multimeters.

Below are some main points to consider before make decision, in simple these are top features which should be included in all top automotive multimeters.

Low Impedance

Automotive circuits are mainly consists of five categories which are charging, ignition , starting , lighting and accessory. As batteries are only primary source of power in cars and other vehicles so all these circuits are powred by 12v or 24v dc systems. Small voltage system means they needs a multimeter which has low impedance so it will not effect circuit or device performance.

It,s the most important thing to consider before selecting an automotive circuit for you. These multimeters usually comes with 10 mega ohm impedance max.

Auto/Manual range

Diy electronics hobbyist don,t know much about using multimeters in start. In that phase it,s good if they get a multimeter which has auto range capability. So they don,t needs to set ranges before every test. On other hand trained professional electricians and auto mechanics can adjust range according to their needs.

So it,s fine if you select a multimeter with both auto and manual ranging options otherwise you should according to your skills level.


In all types of fields and their applications the first demand of troubleshooting is accuracy. Everyone wants accurate results so they may not detrack to find causes of faults and malfunctions. Many top notch multimeter making brands offers supreme accuracy and reliability. We tried our best to present you the most accurate meters in our list so you can do your work conviniently.

Many famous brands like fluke, klien , amprobe , innova and mastech has good accuracy level and they can be trusted well to finalize decision while selecting best multimeters for you.


As a common saying “ safety comes first “ it applies to all fields of life wherever you work wherever you live you has to be always vigilant for safety. In case of multimeters it has to be make sure that multimeter you are using is properly safety rated. Many agencies like UL and ETL are working on product and material safety certifications.

Overload and fuse protections are most basic safety considerations in multimeters. Some standard multimeters built according to IEC standards and completely safe for heavy load installations like CAT2, CAT3 AND CAT4.


Budget is also an important factor for right multimeter,s purchase. As everyone of us don,t have extra bucks to buy expensive multimeters. We give solutions to you by adding low, medium and high price range multimeters in our list. As fas as cost is concern, it depends on nature of use and applications.

If you need a general multimeter for homeuse you don,t need to go for fluke or other expensive stuff. But for commercial and industrial use we strongly recommend you to only select that meters which are properly caliberated and safety rated. Definitely you had to spend extra money for it.
