What Are The Characteristics of The Loop Resistance Meter?

The loop resistance tester is a professional instrument for measuring the loop resistance of switch control equipment. It is designed according to the latest electric power executive standard DL / t845.4-2004, combined with high frequency switching power supply technology and digital circuit technology. GDZX summarizes several features of the loop resistance tester.

I Large Current

The loop resistance tester adopts the latest switch power technology, which can continuously output large current for a long time, overcomes the disadvantage of the instantaneous current of the pulse power supply, effectively breaks through the oxide film of the switch contact, and obtains good test results.

II High Stability

Under the condition of serious interference, the last data of LCD can be stable within ± 1 word range, with stable reading and good repeatability.

III High Precision

The loop resistance tester adopts two-way high-speed 16 bit sigma delta AD sampling and the latest digital signal processing technology, with the highest resolution of 0.01 μ Ω. At present, it is a contact resistance tester that can achieve the resolution of 0.01 μ Ω and is very stable in China, and its performance exceeds that of the imported high current micro ohmmeter.

IV Long Service Life

The loop resistance tester adopts high-precision resistance. Through the ingenious design of temperature compensation circuit, it can effectively eliminate the influence of ambient temperature on the measurement results. At the same time, the use of military connector enhances the anti vibration performance.

V Intelligence

The loop resistance tester uses imported high-performance CPU, and the system automatically switches the measuring range according to the signal size, ensuring the test accuracy of the product. The over temperature protection circuit can automatically stop the output current when the instrument exceeds the set temperature to ensure the safe use of the instrument.

VI Powerful

The current can be freely selected in 50A and 100A, and the test time can be arbitrarily set in 5s-599s, which overcomes the defect that other similar instruments cannot set the measurement time or the continuous working time is too short, and far exceeds the performance of other similar instruments.

VII Friendly Human-machine Interface 

By rotating the mouse to input data, it is convenient and fast. You can set the date and time of the instrument, save the measurement data in real time, and print the measurement results in real time.

VIII Multiple Communication Modes

It can communicate with the computer through RS232 serial port (9-pin) or USB data line, upload the measurement data to the computer for further analysis and processing by the tester.

IX Use Properties

The loop resistance tester is small in size, light in weight and easy to carry. 

Zxhl-100a loop resistance tester produced by GDZX has the characteristics of small size, light weight, strong anti-interference ability, high precision, convenient operation, perfect protection function, etc., and has various specifications such as 200A, 300A, 600A, etc., which are welcome to purchase.
