Product Description

Loop Resistance Tester

I. Purpose and Features of the Instrument

According to the new "Regulations for Handover and Preventive Tests of Power Equipment", the test current for measuring the conductive circuit resistance of various switchgear shall not be less than100A. To this end, our factory has designed and developed a new generation of intelligent loop resistance tester products according to the new regulations. This product is suitable for testing the contact resistance of main contacts of high and low voltage switches, and the DC resistance of high and low voltage cable lines.It adopts100A constant current output. The maximum output voltage reaches10V, allowing the use of thin test leads, greatly reducing the labor intensity of field test personnel. The test process is fully controlled and automatically implemented by a single-chip microcomputer, with high accuracy, good repeatability, simple operation, LCD display of test data, and result printing. Suitable for different working environments.

1. High Current: Using new power supply technology, it can continuously output high current for a long time, overcoming the drawback of instantaneous current in pulse power supplies, effectively breaking through the oxide film on switch contacts, and obtaining good test results.

2. Strong Anti-interference Capability: Under severe interference conditions, the last digit of the LCD screen can stabilize within ±1 digit, with stable readings and good repeatability.

3. Long Service Life: All high-precision resistors are used to effectively eliminate the influence of ambient temperature on measurement results, and the use of military-grade connectors enhances vibration resistance.

4. Portable: Small size, light weight.
