Dear All,
for my lab, i'm building a 4 channel power supply, with two digital DC buck converter (0-36V) and two analog (from different suppliers) XL4015 with display DC buck converter (1.2 to 36V) .
I have two DMM, one Fluke and one ordinary.
By turning on, i get differences, where the DC converter show 14V5, the Fluke shows 14V8 and the ordinary shows 14V7 as example.
And these differences appears on all 4 channels (buck converters).
Is this normal, a difference of 2% to 4% by measuring what the buck display and what the DMMs shows?
Thx in advance!
