Turning the multimeter function dial to the wrong function (amps instead of volts, for example) is one of the most common mistakes people make when using a multimeter. Also, older models that are not auto-ranging could be put into a range that is too high, making the ...
Having a basic toolkit with the following tools is a good place to start. Digital Multimeter (DMM) - A DMM measures multiple electrical quantities, such as voltage (volts), resistance (ohms) or current (amps). Some DMM models include special features that allow you to take minimum, maximum...
