Abstract: A measuring rod for an electric meter and an electric meter assembly using the same are disclosed, wherein the device to be detected disposed around the front end of at least one of the test probes allows the electric meter to determine the type of currently inserted test probes and whether the test probes are suitable for use under a current operation mode of the electric meter in a situation when the device to be detected is inserted into the electric meter; and the measuring socket corresponding to the device to be detected is disposed with a determination mechanism for allowing the electric meter to determine whether the abovementioned test probes or test probes of different types are suitable for use under a current operation mode of the electric meter.

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.
