Anyone who comes into contact with electricity on a regular basis should own a multimeter. There are many reasons why a multimeter can come in handy. Often it is not complicated problems you need to solve when doing electrical work, but very simple ones. But if your multimeter got old or you are looking for your first one then here are a few reasons why they can be so important.
1. They Help to Determine Whether the Device Is Actually On
This might sound silly, but in actual fact, it can be quite hard to tell if the device is actually on when you are trying to solve a problem with it. Sometimes the external readings might not be working on the device, but the internals is all operating as normal. A multimeter will be able to tell you if there is any electricity coursing through the device, which can save you a lot of time trying to determine this in any other way. Only those who have been through the embarrassment of realising that a machine was actually turned off the whole time they were working on it can know why this can be such an important tool, so don't let yourself be counted amongst that number.
2. They Help You Identify How Many Amps Are Currently Flowing Through Your System
To know if something is working or not you need to know just how much electricity is actually coursing through it. If there is too much electricity, then this could be the cause of the malfunctions. If there is too little, then it could be a problem with the source. A multimeter tells you exactly how many amps are in any given circuit, allowing you to quickly pinpoint where the problem is. Rather than spending precious time completing other complex tasks to come to the same conclusion, simply get a multimeter.
3. They Can Help Determine Whether a Wire Is Conductive or Not
Perhaps the scariest thing when working with a live electric current is not knowing whether or not something is actually carrying an electric charge or not. A multimeter removes the guesswork entirely and will tell you safely whether a wire has any active charge or if it is simply laying there dormant. For those that have to work with dozens of wires, cables and circuit boards on a daily basis, a multimeter is a lifesaving and necessary tool.
