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 ...
So, after first measuring voltage with a standard, high-input impedance voltmeter, use a digital multimeter with a low-impedance option, such as the Fluke 117 or 289. These meters offer both a high-input and a low-input impedance function. If the voltage is induced, the low-impedance input...
