After proper calibration procedure obtain specifications for the best cheap switching power supply available on the market.

Original item description:

Features:

Output Terminal On The Front Panel, Use More Friendly
Has Both Lock And Power Display Function (WATT)
Voltage And Current Setting Selector Used Tack Switch Instead Of Slide Switch, Improved The Reliability
Setting And Reading Are More Accuracy,The Resolution of Amp meter is 1mA,Volt meter is 10mV
Ripple & Noise (peak-peak) less than 10mV
Zero overshoot (c.v mode and c.c mode),Protect sensitive device
High efficiency 87%
Intelligent protection: Output short circuit protection, Tracking Over Voltage Protection (OVP), Tracking Over Current Protection(OCP), Over Temperature Protection (OTP) SMD components: Reflow soldering process, higher reliability.

Hello Costel Ban.
Could you please show the calibrating procedure sequence?

Just I killed my device.... Now I see the indication - ECL ECL
