Whether you are looking to test car engines at your auto shop or check all sorts of electrical equipment in your home, getting a new insulation multimeter can help you out immensely. With such a device, you can check for damage, ensure long-term performance for a variety of electrical appliances, while also preventing future problems.

About insulation resistance problems

In an ideal world, electric current would travel through an aluminum or copper wire from the source to the destination. Since all conductive wires have some sort of insulation in the form of a sheathing, there shouldn’t be any problem.

In reality, for various reasons such as aging or damage insulation, electricity is not perfectly contained, which means that it can sometimes escape. Just like water in a broken pipe, current can ‘leak’ out of an electric system and lead to damage or loss of performance. This is where an insulation multimeter can help out.

With a good multimeter, you can now test various devices and systems and spot trouble before it becomes serious.


Conduct insulation testing

There are lots of factors that can lead to a deteriorated insulation. Excessive cold or heat can accelerate the aging of the insulation, and so can high relative humidity in the environment. Spilled oils, dirt, vibrations, or even vapors from corrosive chemicals can all contribute to a loss of performance and trouble down the road.

With a modern multimeter, you can test the integrity wiring or equipment by measuring the resistance of the insulation. You can do that by applying an output DC test voltage to equipment and then by measuring any ‘leaking’. You can then use charts with nominal voltage ratings to help you determine whether the insulation meets the minimum insulation resistance values.


Spot problems early on

You can spot damaged or low-performing insulation, which allows you to decide on repairing or replacing wires and other parts to restore functionality as well as to prevent damage or malfunction. The saying about prevention being better than treatment applies here as well.

It’s far better to invest in a quality multimeter to test a faulty insulation because you’d be able to take preventative measures before anything goes wrong. It’s also easier to replace a few wires or other components than to risk major malfunctions and then have to prematurely replace parts or, in the worst case scenario, entire devices.


Save time

Whether you work as an auto mechanic for a living or deal with any appliance that has electrical wiring in it, a multimeter can save you a lot of time. Rather than blindly looking for problems, you can perform extensive insulation resistance tests to check all the wires in a component and ensure that it is working properly.

In our modern era, cars have become even more reliant on digital technologies, which has resulted in a great increase of electrical components installed in a car. You can test the engine as well as other systems quite fast once you learn to use a multimeter properly.

Doing so eliminates all the guesswork while also allowing you to fix stuff a lot faster, saving you time and actually earning you more money in the process.

Prevent damage and save money

While you might not think of a multimeter as a money saver, it can actually save you hundreds, if not thousands of dollars in repair costs. With the advancement in technology, lots of devices are becoming cheaper.

The downside is that more and more are becoming stuffed with electrical circuits, and that means more things can now break or at least perform poorly when there’s a loss of current. The greater threat, however, is the fact that there are now more electrical things that can break. That’s especially true when there’s a serious problem with the insulation.

With a multimeter, you can replace a few wires on the cheap and save an expensive device from a major malfunction which can be either costly to repair, or even costlier to replace.


Prevent injuries and damage to property

The problem is that faulty insulation can also pose injury risks, as faulty insulation can sometimes lead to someone getting electrocuted. That’s probably one of the last things you want to experience, which is why testing all wires beforehand is a great idea.

You might remember from school that electricity chooses the path of least resistance. Insulation with a lower resistance can leak current which can often lead to short-circuits. These usually generate a lot of heat and sparks, which can easily destroy a device or even cause a fire that could damage your home.

You can prevent all that by getting a decent multimeter and learning how to use it.


Multimeters are affordable

One of the best things about multimeters nowadays is that they are quite affordable. Combine that with the huge variety of makes and models, and you get loads of options that can accommodate any pocket. Getting a multimeter shouldn’t be a huge investment unless you’re a professional who needs to use it every day.

Enjoy a lightweight and portable device

Another advantage of multimeters is that most of them come with a compact and lightweight body. This is not one of those huge devices that you need to haul every day. You can simply put a multimeter into your pocket and carry it anywhere. This allows you to perform tests in other locations without extra effort.


Get loads of functions

A standard multimeter or VOM (volt-ohm-milliammeter) can be used to measure resistance, which is the subject of this article, as well as voltage and current. That makes it quite versatile in itself. You can test a lot of equipment with this little device and get help in many ways.

Modern multimeters sold nowadays come with extra functions as well, as you can measure conductance and capacitance as well as other things such as frequency and temperature. A quality device might also allow you to test diodes, transistors, high voltages, making it a highly versatile tool to have, which can offer long-term performance every time.
