Abstract

The invention discloses a multifunctional clamp meter comprising a master control unit, a signal switching unit, a sound-light alarm module group, a display unit, an electric torch control unit, an operation indication unit, a universal meter detection unit, a digital current measurement device and a noncontact voltage test device. The noncontact voltage test device also comprises a range finding module. An AC / DC current detection module group is the digital current measurement device. A data transmission module is also arranged. The multifunctional clamp meter is simple in structure, and the range finding module is additionally arranged on an existing clamp meter so that detection is enabled to be safer; a high-speed AD sampling module is adopted in the master controller so that data acquisition is enabled to be more rapid and accurate; and finally the data transmission module is additionally arranged so that monitored data can be transmitted to a central control room or mobile storage equipment in real time and the acquired information can be backed up timely.

Description

technical field [0001] The invention relates to a clamp meter, in particular to a multifunctional clamp meter. Background technique [0002] Traditional digital multimeters are popular in the market for their intuitive display, accurate measurement and portability. However, with the development of science and technology, various mechanical equipment, communications, and electronic devices have become more intelligent. On-site inspection and fault diagnosis put forward higher requirements for test tools. High-speed sampling of the measured signal is realized on the basis of the function of the digital multimeter. Reappearance is the demand of the market, and it is also an inevitable trend in the development of tool-type measuring instruments. [0003] The appearance of the clamp meter makes the measurement more diversified, and it is more convenient and fast for high-speed measurement of the measured signal. The existing clamp meter has basically complete functions, incl...
