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 conductor resistance of current-carrying conductors. It can output current stably for a long time and complies with the relevant provisions of DLT845.4-2004 "General Technical Conditions for Resistance Measuring Devices, Part 4: Loop Resistance Tester".
The switch loop resistance tester model 500A loop resistance tester adopts 100A, 200A, and 500A constant current output. The maximum output voltage reaches 10V, allowing the use of test leads with smaller cross-sectional area, greatly reducing the labor intensity of field testers. The entire testing process is controlled by a single-chip microcomputer, featuring high precision, good repeatability, single-button operation, simplicity, and LCD display of test data. It is suitable for measuring contact resistance values in different working environments.
