+ | ====== measurement ====== | ||
+ | |||
+ | When powering the device on, I noticed that the voltage on the display did not change while I was turning on the knob. | ||
+ | But the Digital Multi-Meter (DMM) actually shows that the voltage actually does change. | ||
+ | Just the reading on the screen is inaccurate. | ||
+ | |||
+ | It was time to measure how inaccurate this power supply is. | ||
+ | But doing that manually just takes to long. | ||
+ | So I decided to implement the protocol to control the the power supply, and I will measure the set output using a DMM connected to the computer. | ||
