Loop Contact Resistance Tester

This Loop Contact Resistance Tester is a special equipment for measuring the contact resistance and loop resistance of switch, circuit breaker, transformer and other equipment. Loop Contact Resistance Tester adopts a typical four-wire measurement method, apply DC current between the two end knobs of the measured body, and measured the voltage drop generated by the current flowing through the measured body, and then the DC resistance of the measured body is obtained through the ratio of voltage and current.Loop Contact Resistance Tester is mainly composed of constant current source, preamplifier, A/D converter, indicating device and so on.

1.Adopting high precision electronic circuit and high performance single chip microcomputer, the instrument has the characteristics of fast measuring speed, stable numerical value and good repeatability.

2.Real-time monitoring and display the field resistance value and current value.

3.The output current of Loop Contact Resistance Tester can last more than 1 minute.

4.Test current from high-precision 100A/200A/300A/600A switching constant-current power supply, manual adjustment,with fast test speed and high accuracy .

5.With function of printing, storage, real-time view data ,etc.

6.Large screen display, menu operation, friendly interface, easy to operate.

7.The micro printer is a thermal printer with fast speed and the surface can be directly installed with printing paper.

8.Loop Contact Resistance Tester has the function of interchanging wiring measurement between positive and negative voltage poles and between positive and negative current poles.

9.With RS232 serial port.
