The electronic appliances may often create trouble due to problems in  internal circuits. For their safety diagnosis must be carried out. Multimeters are best suited for detecting electrical issues but you need to choose a type of multimeter that is most compatible with your requirements.

Similarly, the multimeters that are designed specially to solve vehicular problems are called Automotive multimeters. Their features are best suited for diagnosing problems in car engine, battery, sound systems. Here we are some of the most efficient automotive multimeters. The automotive multimeters need to be highly accurate.

The accuracy is most required feature by a DIY mechanic. The automotive multimeters can help you solve many other vehicle issues such as checking your speaker. Almost all the automotive multimeters are designed with easy to use features and even a non professional can use it for troubleshooting. It's easy use saves the money you pay to a technician.

Things to Consider Before Buying Best Automotive Digital Multimeter:

In order to make smart choice, you must acquire the prior knowledge for buying. Here we are discussing some aspects that will help you make correct decision when buying an automotive multimeter.

i). True RMS

The true rms in multimeters is used to measure the waveforms with greater accuracy. All multimeters can measure the rms values from the smooth sine waves when there is distortion in wave forms it becomes difficult for normal meters to measure them accurately. 

The True RMS meter will can measure the sinusoidal and non sinusoidal waveforms accurately. Although these are expensive but the correct working will make you believe that you have invested money on right place.

ii). Overload Protection

Find multimeter with reliable circuitry protection thermositers or fuse.To safe an instrument from hazard of voltage stresses it must have overload protection feature. The multimeters must be equipped with good fuses and advanced circuitry protection like PTC and HRC fuses which provides enough protection.

iii). Auto Ranging

The manual ranging features in which the user has to set the voltage range manually can irritate you if you don't have knowledge of the color codes.In auto ranging the range is automatically set by the multimeter that saves your time and effort.

iv). Non Contact Voltage Testers

Non contact voltage testers are the safest way of checking power.

For verifying the presence or absence of power you don't have to touch the conductors therefore the personal safely is well maintained by non contact voltage testers.

v). Protective Covering

The rubber covers provides a little more protection. In case of drop the smooth rubber covering would protect it from damage. This will definitely increase the life of your multimeter.

FAQs:

Q1) Are all the multimeter suitable for the measurement of non sinusoidal waveforms?

No, all the multimeters can't measure the non sinusoidal waves accurately. The true rms multimeters are designed to measure the non sinusoidal waveforms with higher accuracy. It can measure sinusoidal and non sinusoidal waveforms as well.

Q2) How can we test car battery with automotive multimeter?

First do the multimeter setting and adjust voltage to 20 V DC current because the car battery uses DC current. After that turn off lights and ignition. Then, connect the wires to their respective terminals. Black wire is connected to the negative terminal and black wire is connected to the positive terminal.

Q3) How can we find a meter with good overload protection?

To find out a multimeter with good overload protection you should ask that what kind of fuse or circuitry protection has been used in it. Sometimes the cheap fuses like gas fuses can not giveenough protection. The HRC fuses advanced cirtuit protection like PTC must be present in multimeters.

Q4) What is the advantage of auto-ranging over manual function?

The auto ranging function is time and effort saving because you don't have to set the range and the range is automatically set by multimeter but you have to manually set the range when you use manual function.

Q5) How do we know that the circuit is complete while carrying out a continuity test?

When you do continuity test and the circuit is complete. The meter notifies you through beef. If the circuit is not complete, the meter will not beep.

Q6) Which factor must be considered for long-lasting use of multimeter?

The durability of the material is an important factor for the long life of multimeter. The material quality must be asked for the long-lasting use.

Final Words:

We have discussed multimeters for vehicular use detail and observed the criteria for buying an efficient multimeters.

The most valuable features have been recognized that can help in solving automotive problems such as engine issues and battery check. 

A number of important features like overload protection, True RMS and non contact voltage testers. Further, the features that adds to the ease of use like auto-ranging, backlight, large LCD.

The overload protection is possible by PTC circuit protection or high quality HRC fuse. The true RMS function can provide enhanced accuracy with the ability to measure sinusoidal and non sinusoidal waveforms. The non contact detectors will detect the presence or absence

The presence or absence of power without the need to touch and give greater safety. The  auto-ranging function automatically sets the voltage.The backlight help electricians working in dark areas and a large LCD that gives the large and clear display of the numbers and graph.

We have observed all these attributes in above mentioned multimeters and these attributes make them perfectly usable in solving automotive problem.
