Product description

Product Introduction

　　NR5300 series loop resistance tester is refined with advanced high-power switching power supply technology and advanced electronic circuits. It is a special test instrument for high and low voltage switches, wire and cable and weld contact resistance.

Main Feature

　　◆ Combining hardware and software design: using high-precision electronic circuits and high-performance single-chip microcomputers, the instrument has the characteristics of fast measurement speed, stable numerical value, and good repeatability;

　　◆ Real-time monitoring and display of field resistance value and current value;

　　◆ The current lasts for more than 1 minute, which is in full compliance with JJG 1052-2009 loop resistance verification regulations;

　　◆ The test current is a high-precision 100A switching constant current power supply, no manual adjustment is required, and the test is fast and accurate;

　　◆Menu operation, friendly interface, clear at a glance, easy to operate;

　　◆ It has the function of interchangeable wiring measurement between the voltage positive and negative poles and the current positive and negative poles.

Technical Parameters

　　◆ Input voltage: AC 220V±10%, 50Hz

　　◆ Test current: DC100A DC200A (Test current can be customized according to customer requirements)

　　◆ Accuracy: 0.5 level

　　◆ Resolution: 0.1uΩ

　　◆ Measuring range: 0 ～40mΩ

Remarks: According to customer needs, it can be customized to meet the supporting construction of the National Grid Electrical Equipment Intelligent Internet of Things Platform (EIP) digital factory, the construction of the experimental data collection platform, and the data collection and uploading.
