Ask any electrician about their most-used tool and the answer hardly changes. Long before the fancy imagers and analyzers come out, a Digital Multimeter is what settles the basic question on every job: is this line live, and is it behaving the way it should? It is the first tool reached for and often the last one packed away. In fact, industry surveys consistently show multimeters among the top three instruments technicians carry daily, which says a lot about how much trust rides on that little screen. When the reading has to be right, guesswork is not an option.
