Thaum siv DC tswj fais fab mov, thaum kho qhov hluav taws xob, nws pom tias tsis muaj -load voltage tsis tuaj yeem hloov kho.
Some operators like to turn the "current adjustment" potentiometer to the left, so that the no-load voltage of the power supply cannot be adjusted. This shows his lack of substantial understanding of "current regulation". Because the power supply consumes a little current even if it is no-load, and if you turn off the "current regulation" to zero, even a small current will not be released, and of course the no-load voltage will not rise. Therefore, "current regulation" is generally not adjusted to zero (the above situation will not occur if it is adjusted to the right to about a quarter of a turn).
Txoj kev ua haujlwm dav dav: Thaum cov zis hluav taws xob ntawm qhov chaw tswj tau siv, lub qhov rooj hloov kho tam sim no yuav tsum tig mus rau lub moos kom kawg thiab khaws cia. Kho lub qhov hluav taws xob hloov kho qhov rooj kom tswj tau qhov tso zis DC voltage tus nqi. Thaum tso zis tam sim no raws li qhov chaw nyob ruaj khov, tig lub qhov hluav taws xob hloov kho qhov ntsuas lub moos mus rau qhov kawg thiab khaws cia. Kho qhov hloov kho tam sim no los tswj cov zis DC tam sim no tus nqi.
