In this guide we’ll show you why multimeters are so useful and where to purchase the best multimeters around! Multimeters are electrical instruments used to measure parameters such as voltage, current and resistance. Multimeters are designed as either analog or digital, analog multimeter measurements are displayed by means of a scale and needle and digital multimeters display results on an LCD screen.
Digital multimeter manufacture and design are more aligned with the way of the world, where technology has become an aspect everyone needs to be mindful of as it makes life easier and enables efficiency when measuring parameters.
Why Do You Need a Multimeter?
So if you are an electrician by profession, you obviously know the answer to this and owning a multimeter is imperative to running your business right? Using a multimeter to test electricity and electronics is how you make a living. If you have ever booked appliances in for repair, only to get a call that the only solution is to replace it, has probably made you want to pull your hair out! Solve the problem by purchasing a multimeter easy enough for you to use at home and then you can check your appliances yourself. Most digital multimeters are so advanced that the variety of LED color lighting is able to tell you whether to get something fixed or just replace it.
How To Use a Multimeter
All multimeters generally work on the same basis, it is however imperative to read the instructional guide that comes with the device before use. Ensuring that you match probes to the correct polarity terminals (positive or negative) is as difficult as it gets when using a multimeter. The red probe is positive and the black probe is negative. After using the probes to measure voltage or current the most common means of getting your multimeter back to ‘zero’ is by touching the two probes together. Ensuring that electricity is turned off (preferably at the main switch) will ensure that you do not shock.
The Most Common Uses of a Multimeter
The vast majority of items in your home and your motor vehicle is powered by electrical current. There are two types of current AC (alternating current) and DC (direct current). AC powers most of the items in your home and DC is the electrical power current found in your car. Depending on the settings you choose you can measure whether or not there is an electrical current flowing through electrical plugs, extension cords or motor vehicle batteries. The device allows you to measure this while electric current is off and this is the first point of establishing whether you have to call in a professional (if you are not one already) or whether there is just a power outage.
