For this step to work out smoothly, you need to do a basic test first. The next thing to do using a multimeter is to check for voltage and resistance. Read more:- In-Circuit Testing Step-4: Measure Voltage and Resistance: Then switch it on and make sure that you do not touch any of the wirings. Thus, to know if all parts are working in sync with each other, you first need to unplug the device and the housing. We all know that circuit boards are made up of many components in general and are placed inside an electrical device. The circuit board and the overall voltage will then be displayed on the device. In case you have to test the power or voltage, turn the function knob or select the AC or DC voltage. Multimeters are modeled in such a way that they can measure both voltage and resistance.
Here comes the critical step wherein you need to select the multimeter function first to check a circuit board. While the red one is the positive probe, the black one is the jack at the end of the probe wire. Every multimeter device comes with two types of probes, namely red and black. For this step to work out, you first need to observe the polarity and then probe in the multimeter. This is the first and basic step in circuit board testing. Guide To Test A Circuit Board Using Multimeter: Step-1: Plugging : Below we have outlined the different steps that can be used to test a circuit board with the help of a multimeter. Today the advent of science and technology has introduced many types of equipment, which gradually lessens our work.Įven if you don’t know the basics of an electrical circuit board and multimeter, you can easily learn the same using this blog. But the main question that arises is how to test a circuit board using a multimeter. Only then you can track down the faults and adopt a logical approach for doing so. Not many people know this, but before using a multimeter for finding faults in a circuit, it is necessary to have a little knowledge about electrical types of equipment. However, when it comes to test a circuit board with a multimeter, there are many discrepancies.
Multimeter today come in two variants, i.e., one is analog and the other digital. One of the main reasons why Multimeter are widely used today is because they can find faults within a piece of electrical equipment very easily. While the former is used for troubleshooting, circuit boards, on the other hand, are used in varied electrical equipment. Multimeter and circuit boards are two things that go hand in hand.
