Product Description

Product overview:

This instrument features an ergonomic control panel designed for user-friendly operation. Utilizing high-frequency switching power supplies and digital circuit technology, it is specifically engineered for measuring loop resistance in switchgear circuits. The test current complies with the national standard's recommended 300A DC current. Capable of directly measuring loop resistance at 300A DC, the device displays results on a large LCD TFT screen while offering essential functions including data storage, print output, and time settings. Users can select from three current ranges: 100A,200A, and 300A. Customizable testing duration allows up to 60 seconds, making it a highly reliable contact resistance tester that outperforms imported high-current microohmmeters. Designed to meet field maintenance requirements for high-voltage switchgear in power supply departments and circuit resistance testing specifications for switchgear manufacturers.
