At the same time, the resistance tester is a relatively sophisticated instrument and its safety during carrying needs to be ensured to prevent it from being bumped or dropped. Based on this, the present application proposes a portable resistance tester that can effectively overcome the above problems and ensure the portability and safety of the resistance tester.
