Portable current detection recording device

Abstract

The invention discloses a portable current detection recording device. The portable current detection recording device comprises a shell, a power supply, current sensing modules, an A / D conversion module, a controller and a display control module, wherein the current sensing modules are connected in parallel in a plurality of different current sections; the display control module is used for displaying detection data, storing the detection data and inputting the selected current section; and each current sensing module comprises a current sensor and a sensor switching relay. The portable current detection recording device is simple to carry and convenient to detect, the detection data can be stored and analyzed for a long time, long-term data tracing can be carried out, moreover, the detection range is large, the current section selection is flexible, and different equipment current requirements can be met. In addition, by arrangement of a USB flash disk interface, the detection data can be read and analyzed on a computer. By arrangement of a network cable interface, networking can be implemented, and remote real-time monitoring is realized.

Description

technical field [0001] The present invention relates to the technical field of current detection, and more specifically, to a portable current detection and recording device. Background technique [0002] Devices that can detect small currents and record data are generally fixed or bulky devices that are inconvenient to move, and some are developed for a special purpose device. Therefore, for the existing small current equipment, equipment with micro-leakage current, and production line leakage current detection, it is mainly to use a multimeter or related equipment to detect the current value, but some current values ​​change, or even change irregularly. Equipment is difficult to monitor for a long time and perform effective analysis. Moreover, in addition, the current limit of general detection equipment is relatively rigid, and it only detects the current of one section, which has poor flexibility. For example, Chinese patent CN206411185U discloses a large current detec...
