General introduction

Low resistance tester output DC 50A/100A/200A current to test the sample resistance. It is designed according to IEC62271. The main application of the tester is measurement of circuit breaker contact resistance. All the test results of the tester could be print by the micro-printer which is integrated in the tester. Also all the test results saved in the tester could be upload to PC computer and then convert to MS WORD document.

Advantage

1) Design with hardware and software: endowing the instrument with some features such   
    as high measuring speed, numerical stability, and good repeatability and so on by  
    using electronic circuit of high precision and SCM of high performance. 
2) Real-time monitor will display site resistance and current.
3) If the duration of current is over 1 minute, it completely accords with the verification 
    regulation of JJG 1052-2009 loop resistance.
4) 100A/200A/300A/600A or 100A/200A/400A/600A switch constant-current supply of 
    high precision, for testing the current, can test quickly and accurately without manual 
    adjustment.
5) It has the functions of printing, storing, real-time viewing data and so on.
6) It is with a large screen to display characters, menus to operate, and friendly interfaces 
    to understand and process Easily.
7) Miniature printer is thermal printer with fast speed, which can be installed printing 
    paper directly. 
8) It can also measure when exchanging wirings between positive and negative poles of 
    voltage, and between positive and negative poles of current.
9) Manage the data of equipment through serial port RS232 instead of paper.
