CuVoodoo #011 – believe in what I do, not what I say

testing the accuracy of a power supply:
It was time to get a decent power supply, and so I found the EA-PS 2084-03B. It fulfilled all my criteria: good quality, silent, wide voltage range, and most importantly with PC connectivity. But somehow the reading on the LCD does not match what is output. So I implemented a program to remotely control and monitor this power supply, and with a PC connected UT61E multimeter I can compare what is set to what is output. This way I can measure the power supply's accuracy.
