High Current Contact Resistance Tester With Color Touch Screen

As a professional manufacturer in China, Weshine would like to provide you quality High Current Contact Resistance Tester With Color Touch Screen, which is an upgraded intelligent resistance meter made for high-voltage device contact testing. Injecting large test current strips away interference from surface oxidation layers and unstable contact points, so testers get trustworthy readings for equipment pre-maintenance inspection and factory acceptance checks. Bulk purchasers can match this unit to their full electrical testing tool kits for one-stop procurement.

Users can pick adjustable output current from 50A up to 600A, matching test criteria and rated parameters of different electrical devices. The high-current test mode accurately judges contact condition on circuit breakers, GIS equipment, disconnecting switches, busbars and cable joints, a must-have tool for factory inspection teams and power engineering contractors.

This  High Current Contact Resistance Tester With Color Touch Screen adopts a 7-inch industrial color touch screen with easy-to-navigate operation panel. Staff can quickly set output current, test timing, system language and communication parameters on screen, view real-time test waveforms and manage stored data with minimal training. It cuts on-site operation time for engineering teams handling large batches of equipment inspection work.

Equipped with a large built-in rechargeable lithium battery, the unit supports fully portable outdoor testing without mains power access. After 500A or 600A heavy-current tests, it triggers a 10-second auto cooling cycle to shield internal power modules, extending service life and lowering long-term replacement costs for buyers with frequent field testing tasks.

It carries multiple data transmission modes: Bluetooth wireless link, RS232 wired connection, USB flash drive export and local storage. Operators can browse, save, export or delete test records directly on the machine, speeding up test report sorting and equipment asset management for power station tender projects and factory quality control departments.

Built to withstand harsh outdoor job sites, the VS-5206 merges powerful high-current output, precise digital measurement, multi-layer safety protection and durable housing. It delivers consistent reliable test results for daily equipment maintenance, new project commissioning and electrical fault diagnosis, ideal for wholesale orders from electrical equipment distributors and power engineering firms.

Product Guide

How the  High Current Contact Resistance Tester With Color Touch Screen Works

This tester injects a stable high DC current into the test object through dedicated current leads while simultaneously measuring the voltage drop across the contact using separate sensing leads. Utilizing the four-terminal Kelvin measurement principle, the instrument eliminates lead resistance and calculates highly accurate contact resistance values.

After the selected current stabilizes, the tester automatically performs measurement and stops output upon completion. When operating at 500A or 600A, the instrument automatically activates a cooling cycle before the next measurement to maintain system reliability.
