The system is a set of Holzer effect, magnetoresistance, I-V characteristic test in one of theautomatic test system. The system fully considered the instrument configuration, the circuit connection (including connection and low temperature chamber) and other users often ignore the problem, select the electrical measuring instrument American Keithley, magnetic fieldaccording to user needs by electromagnet or without liquid helium superconductive magnet,equipped with measuring sample rod smart, full automation special test software plus, can let the user sample test quickly and easily, and get the accurate and reliable data.

Electric transport measurement system is a set of Holzer effect, magnetoresistance, I-Vcharacteristic test in one of the automatic test system. The system fully considered the instrument configuration, the circuit connection (including connection and low temperaturechamber) and other users often ignore the problem, select the electrical measuring instrumentAmerican Keithley, magnetic field according to user needs by electromagnet or without liquid helium superconductive magnet, equipped with measuring sample rod smart, full automationspecial test software plus, can let the user sample test quickly and easily, and get theaccurate and reliable data. In addition, there are a variety of cryogenic system options, and can carry out special modification of existing instruments according to user requirements andthe special software, is a powerful tool for scientific researchers to study the resistivitymeasurements on samples.

The main features:

1) standard system uses plug-in sample sample fixture, easy installation;

2) the basic configuration at a time can be attached with four samples, and also can be testedon a sample of two;

3) standard system of random distribution of a probe sample card;

4) standard measurement system can I-V characteristics of the Holzer effect, the differentmagnetic field;

5) resistance wide measuring range: 0.1M 50G (omega - Omega high resistance system), the uncertainty of measurement is 2%;

6) test procedure and calculation process is automatically performed by the software, and save a lot of time;

7) software can display the measurement results and measuring curves;

8) the closed-loop control system can provide high stability of the magnetic field, magnetic field, and solves the problem of realizing zero magnetic field magnet remanence, real;

9) select temperature options, can be measured Holzer effect measurement and the characteristics of I-V under different temperature.
