Abstract
The present invention relates to a watchdog timer dedicated to the display controller of a voltage detector wherein the watchdog determines a malfunction in the microcontroller and triggers a visual warning to be displayed via the display controller. This prevents inaccurate voltage information from being displayed in the case of a microcontroller malfunction and thereby the user from being exposed to the risk of extreme injury through, for example, a high-voltage shock.
