ABSTRACT:
An auto-measuring universal meter is disclosed. The auto-measuring universal meter includes a main unit having a display and a single button. A pair of test probes is electrically connected to the main unit in a removable manner to detect a first input signal; an inductive clamp is formed on and electrically connected to the main unit for gripping a current-carrying conductor to detect a second input signal indicative of an alternating/direct current flowing through the current-carrying conductor. The main unit is designed so as to take measurement of the input signals in a self-judging mode based on the presence of and/or the differences between the input signals so that the alternating/direct current can also be measured.
