Basic Contact Resistance Tester

1. High current: For latest power supply technology, the tester can continuously output high current which overcomes the weakness of instantaneous current produced by pulsed power. It can effectively breakdown/puncture the oxide layer of the switches and then get precise results.

2. Strong anti-interference ability: The last number of test data will stably show in the LCD screen only with ±1 error even in strong Interference situation.

3. Long service life: All the precise resistances used in the tester can reduce the temperature's impact on the measurement results and connectors can enhance vibration resistance.

4. Convenience: Small size, light weight.

The operation panel of JH1001 Loop Resistance Tester adopts an ergonomic design that conforms to operating habits. It adopts high-frequency switching power supply and digital circuit technology, and is suitable for contact resistance measurement test as well as measuring the circuit resistance of switch control equipment. The testing current adopts the DC 100A recommended by the national standard. The circuit resistance can be directly measured at a DC of 100A, and the test results are displayed on a large LCD screen with functions such as data storage, output printing, and time setting. There is also a 50A gear available for users to choose from; Customized testing time, with a maximum set time of 599s, which is much longer than the standard requirement of 600s; It is the only one in China that can reach 0.01 μΩ resolution and very stable performance surpasses the imported high current micro ohmmeter. Meet the requirements of on-site high-voltage switch maintenance and high-voltage switch factory circuit resistance testing by the power and power supply departments.

Suitable for high-precision measurement of contact (circuit) resistance of high and low voltage switches and DC resistance of cable lines, as well as other occasions that require high current and micro resistance measurement.
