The M4000 M4100 is a high performance test set that features a 300 milli-ampere output current at 10 KV. It has the capability to generate its own sine wave test signal for accurate measurements. This test set measures power factor, tan delta, excitation current and capacitance. Depending on the environment in which the testing is being performed, electrical interference can significantly affect the test results. To address this potential problem, The M4000 M4100 features interference rejection capabilities to reduce the impacts of electrical interference on measurement accuracies.
