Abstract

An invention relating to a series resistance measuring device is disclosed. The disclosed series resistance measuring device is characterized by comprising: a first probe made of a conductive material and electrically connected to one side of a body; a second probe made of a conductive material and electrically connected to the other side of a body while being prevented from being directly connected to the first probe, and connected together with the first probe to a vehicle continuity test target to detect whether the continuity test target is short-circuited; and a test kit that integrates the first probe and the second probe by connecting them with an insulating material, thereby allowing one to hold at least one of the first probe and the second probe with one hand and guide the detection of whether the continuity test target is short-circuited.

Description

Series Resistance Measurement Apparatus The present invention relates to a series resistance measuring device, and more specifically, to a series resistance measuring device that provides convenience in short-circuit testing of a fuse by connecting a first probe and a second probe, which are each electrically connected to a body, to each other as a test kit so that the first probe and the second probe can be held simultaneously with one hand to test for a short circuit of the fuse. To check for a short circuit in a fuse applied to a vehicle junction box, you can use a multimeter to touch both ends of the fuse to verify whether the internal connection is short-circuited. Typically, a multimeter consists of a main body and (+) and (-) test probes. In particular, open/short circuit testing (conduction testing) of components (junction boxes) can be performed through the current function settings. That is, the operator removes the fuse to be tested from the vehicle, such as the junction box, sets the multimeter to continuity testing, and then contacts the (+) and (-) test probes to both ends of the fuse to be tested. Upon contact, if the fuse is not short-circuited, the multimeter buzzer will sound. Conversely, if the fuse is short-circuited, the multimeter buzzer will not sound. As background technology for the present invention, Korean Registered Patent Publication No. 10-1104846 (Registration Date: January 4, 2012) discloses a "vehicle fault inspection device." The technical configuration described above is provided as background technology to aid in understanding the present invention and does not constitute prior art widely known in the technical field to which the present invention belongs.
