best multimeter

Whether you are a professional auto technician or a do-it-yourself hobbyist, your toolkit will not be complete without a multimeter. There is no doubt that this is one of the most useful diagnostic instruments to have in your garage.

​After all, there are many electrical components found in all new cars. Without checking and making sure that they are all working perfectly, you might suddenly experience your ride breaking down or malfunctioning.

It’s important to have the best multimeter for automotive use so that you can avoid such situations.​

​A multimeter, based on its name, is a combination of different meters so that it can measure different things. This is why this tool is not just useful for automobile maintenance and repair, it is also normally used at home.

​While it can be tempting to buy one with the most features possible, if you are purchasing one to use with your car, you should focus on the functions that you really need.


​Parts of a Best Multimeter

​The multimeter, because of its many uses, will have quite a few parts that have their own purpose:

  1. ​The Dial is found in a display window and is a scale that has the shape of a half circle. The results of readings will be displayed here.
  2. ​The Selector switch makes it possible to move between measuring amps, volts, and ohms.
  3. ​The Lead openings contain 2 sockets, the first one being COM or Common. The second is the V or O, which means volts and ohms.
  4. ​The Test Leads make it possible for your to connect your multimeter to the part of the car you are measuring.
  5. ​The Battery and fuse compartment provides the tool with power as you are using it.
  6. ​The Zero adjustment knob is specifically for adjusting the rate of ohms, or the resistance.

Main Multimeter Measuring Functions


The Ammeter Feature

​This type of meter measures the current flowing through a conductor. In order to do this, you have to detach or switch off the circuit that you want to test.

​Afterward, you connect the two ends into the meter so that the current passes through the machine. It will then state how many amps are flowing through.


​The Voltmeter Feature

​With this meter, the electrical pressure, measured in voltage drops, of a resistance can be tested. In comparison to measuring amps, you will not need the circuits to pass through the meter.

​Instead, it should be connected parallel to the circuit in order to make a reading. What sets a multimeter above a normal multimeter is the fact that a variety of voltages can be checked.


​The Ohmmeter Feature

​A multimeter is also capable of measuring how much resistance components have and at the same time, the integrity of the car’s electrical circuits. All of these readings are shown in ohms.

​The meter’s leads are linked and it will show the maximum resistance. Should the result say OL, or out of limits, it means that resistance is very high and no current is able to flow through.

​It may also be used to check the resistance in coils. Still, you should always check the plastic coil just in case some cracks appear. This may indicate defects, even if no issues come out during self-testing.


​What To Look For In A Multimeter

​Finding the right multimeter for you can be tricky, so you should keep some of these things in mind when scrolling through the options:


​Type of Multimeter

​First of all, it is best to identify what kind of multimeter you need. There are two kinds, analogue and digital. The former is traditionally popular but the latter is well loved due to its innovation.

​If you are also looking for a more general multimeter you can also use around the house, then check the features to make sure that it incorporates the functionality that you need. However, it might still be better to invest in one that is optimized for car use if you will be mostly using it this way.


​Accuracy

​The purpose of the multimeter is to take measurements. Therefore, accuracy is very important to correctly diagnose the electrical components of your car.If you are buying your multimeter online, it is not possible to test it beforehand, so look for one that has great reviews on its accurate readings.


​Ease of Use

​If you are not a professional auto mechanic or electrician, you might find it tricky to get a very advanced but user-unfriendly device. The display should, first and foremost, be clear and easy to read.


​Safety

​Considering that you are dealing with electrical parts, it is very important to get a unit that is safe and will not injure you in case of malfunction. Some multimeters might be cheap, but maybe it is because of its substandard materials.

Of course, there are more factors, like the price for example (if looking budget option, go here), but those four above are essential to focus on.
