Abstract

The invention discloses a multifunctional semiconductor resistance tester, which comprises a mainframe. A detector interface, function buttons, a power button and a display screen are arranged on theouter wall of one side of the mainframe; the power button is located on one side of the display screen, and the detector interface is arranged above the power button; the function buttons are arrangedabove the detector interface; the top end of the mainframe is fixedly connected with a handle; an AD converter, an STC89C52RC single chip microcomputer and a storage battery are arranged inside the mainframe; the AD converter is arranged on one side of the STC89C54RC single chip microcomputer and the storage battery is arranged on the other side of the STC89C52RC single chip microcomputer; and atest board is arranged on one side of the mainframe. According to the multifunctional semiconductor resistance tester in the invention, a lifting platform is supported and fixed through four support rods, thereby avoiding inaccurate measurement data caused by insufficient contact of a detector probe; a clear view can be provided through an LED lamp installed on the lower end of the lifting platform, thereby bringing convenience for an operator to grasp the lifting distance, and improving the operation accuracy.

Description

technical field [0001] The invention belongs to the technical field of resistance testers, and in particular relates to a multifunctional semiconductor resistance tester. Background technique [0002] The resistance tester is an indispensable tool for electrical safety inspection and grounding project completion acceptance. Including ground resistance tester, insulation resistance tester, DC resistance tester, surface resistance tester and loop resistance tester. The loop resistance measuring instrument (transformer loop resistance tester) is suitable for testing the contact resistance value of the main contact of the high and low voltage switch, the DC resistance value of the high and low voltage cable line, etc. The intelligent loop resistance tester adopts 100A constant current output. The highest output voltage is up to 10V (2-3 times that of conventional instruments), and the test line with thin surface can be used, which greatly reduces the labor intensity of on-site...
