The unit displays voltage just as expected. The "panel mount" listing is optimistic - there is hardly any plastic to the tiny tabs that are supposed to grip a panel to prevent the unit from popping out. Be prepared to glue the unit into place - outside of the mentioned tabs there is no other provision for a mechanical mount.
