It is a lightweight, half rack size power meter. They improve basic accuracy and bandwidth and are widely used in power measurement from low-frequency equipment to frequency converters. In addition, the WT210 has the same 5MA current input range as the WT200 and can measure small currents in energy efficient design and intermittent operation equipment.
