3) Check if there is a short circuit or even an open circuit in the capacitor. Step 4: Check the integrated circuits related to the circuit board, as well as the indicators of resistors and other related devices. 3.Online measurement method 1) Power on the circuit board and check if the...
Set your multimeter to the lowest setting for resistance (the word "ohms" or an "Ω" symbol can also denote resistance). Touch the red probe to the black probe. Check the display to make sure that it reads "0," as there should not be any resistance between the two probes. Find a ...
Check continuity of the capacitor. Set the multimeter to the continuity check setting. Touch the black lead to the ground side of the capacitor and the red lead to the other side. If continuity exists (you'll hear a long beep), the capacitor is short-circuited and should be discarded. St...
This course will transform you from a beginner to a Pro. Topics that we will be discussing in this course are : How to use the Multimeter in the correct way. Definition & Types of Resistors; Resistor's Symbols & Code Calculation;
How to test Integrated Circuits using the multimeter; How to test the TRIAC with multimeter; How to test all types of diodes on a circuit; How to test the Relays and Transformers; How to test Voltage Regulators; How to test Current Sense Resistors; How to test 3, 4 and 8 pin MOSFETs ...
How to Measure AC Voltage with a Multimeter The next in learning how to use a multimeter is to learn how to check AC voltages. The setup is basically the same. First, make certain your red lead is plugged in to the V or voltage banana jack and not one of the others! Move the rotar...
A multimeter provides one of the easiest ways to measure alternating and direct current (AC & DC). We provide some of the key guidelines . . .
They cost less than 1 cent each, but humble resistors are an essential tool no matter what electronics you are building. In this reference guide we look at using them in projects, and how to identify the correct resistor for your project.
First take a look at the speaker driver: take a multimeter, set it to measure resistance and check the driver’s terminals. If you get the reading around 2, 4, 8 or 16 Ohms, then the driver’s coil should be OK. If you don’t get any reading at all (the circuit is open) that...
