Hi.
You are measuring a line with no load. Take that into consideration. An LM2596 regulator can vary 0.1%, with a tolerance of 4% of the set voltage of the ADJ(ustable) model... so a 5.0V set ...

5.0 and 5.22 ?? eh? so it differs slightly? i wonder whether the diffrence is much higher in upper voltage levels
Tarafından pesoft16/04/2017Product work fine but it first showed unprecise voltage value but it can be calibrated (both input and output separately that is good point)
Press left button to display input voltage, press right button for 3 secs, display go off, then release button, display will blink, then adjust using left/right buttons according to your voltmeter and press right button 3 seconds again to save.
Now to calibrate output, press right button to show output voltage, press right button 3 secs... calibrate... press
Tarafından Belik23/11/2013Очень качественная плата. Выполнена отлично. Все функции заявленные продавцом,работают. Вольтметр показывает достаточно точные значения с довольно хорошей реакцией. Можно замерять как входное так и выходное напряжение, а так же выключать вольтметр при необходимости. Очень
