Product Features of High Precision Loop Resistance Tester: The loop resistance tester, also known as contact resistance tester or high-current micro-ohmmeter, is mainly used for
high-precision measurement of circuit breaker contact resistance and current-carrying conductor resistance. It can output current stably for a long time, complying with the relevant provisions of DLT845.4-2004 "General Technical Conditions for Resistance Measuring Devices, Part 4: Loop Resistance Testers".
The switch loop resistance tester model 500A loop resistance tester adopts constant current output of 100A, 200A, and 500A. The maximum output voltage reaches 10V, allowing the use of test leads with smaller cross-sectional area, greatly reducing the labor intensity of field test personnel. The entire testing process is controlled by a single-chip microcomputer, featuring high precision, good repeatability, single-button operation, simplicity, and liquid crystal display of test data, suitable for measuring contact resistance in different working environments.
