This procedure should be used to measure if there is anything wrong with the circuit, like in normal mode a circuit uses for example 100mA, if one now only uses 50 or 150, there must be something wrong.
Load the software and run it; use a multimeter to measure current consumption.
Later you can replace the multimeter by something more advanced which can measure current consumption and compare against known limits.
If you only want to test the processor, just build something with a ZIF socket and measure the current consumption.
