The 2558A is a cost-effective, high-precision instrument capable of outputting a wide range of AC voltages and currents for the calibration of AC measurement devices such as analog wattmeters, power meters, clamp-on testers, and current transformers. Intuitive front panel controls and various computer interfaces enable the 2558A to be operated manually or become integrated into an larger system.
