For troubleshooting purposes, I am needing step by step instructions for assessing the DC output voltage for a Gateway AC adaptor. The brick of this adaptor indicates the DC output voltage should be 19v and 3.42A. The instrument available to determine the DC output voltage is a Velleman (DVM850BL) Meter. Any multimedia link, like a YouTube video, would be perfect for addressing this interest if one is available.
Any guidance or direction given to this technical interest will be deeply appreciated.
