Now we're going to add the 4-pin socket into P4. These pins provide test points where you can connect a voltmeter and ammeter across the power supply to take power measurements.

A multimeter is a device that allows you to measure voltage and current in an electrical circuit. With this socket, you can determine the power consumption of your LameStation.
