AC panel meters require periodic maintenance to check for linearity, hysteresis, and accuracy. A device that can accurately and reliably sweep voltage and current across a wide range would be ideal for this task. In this video, Yokogawa applications engineer Larry Walsh demonstrates how to use the 2558A AC Standard to ramp AC voltages and perform needle sticking tests on analog current and voltage meters.
An AC voltage and current standard is used as a trusted reference for the cost effective calibration of AC measuring instruments. The 2558A can be operated manually with intuitive front panel controls or programmatically via a remote computer interface.
Power Meters and data acquisition systems are used in many applications in the test and measurement industry. However, other situations require standalone devices that can source a variety of precise voltage and current waveforms, as well as allow integration into a larger test system.
