ABSTRACT:
A clamp-on multimeter includes a body section, and a clamp section having a pair of clamp cores for clamping a conductor to be measured. The front ends of the clamp cores are capable of closing and opening. An input section receives signals introduced from a conductor. A display section simultaneously displays a first parameter corresponding to an induction voltage induced in the clamp section, and a second parameter corresponding to the measured signals input via the input section. A control section controls the simultaneously display of the first parameter and the second parameter on the display section.
