Multifunction hand-held Working Standard of power and energy for on site meter testing
The Working Standard WS 2×20 is a single-phase (WS 2120) and three-phase (WS 2320) precision reference meter for electrical power and energy measurement, dedicated to on-site meters testing. The device can be used also as hand-held unit for local data exchange with smart meters (programming and data readout of meters). The device is designed for operation in single, two and three-phase systems, where it evaluates and displays all individual quantities per phase and cumulative three- phase ones as well. Universal inputs can be equipped with any combination of interchangeable precision voltage sensors working up to 600 V and current sensors working up to 6000 A or more. Measurement is based on precision A/D conversion and DSP technology and enables accurate high-speed real time evaluation of all main and informative quantities. Beyond measurement of power, voltage, current and phase the device indicates voltage sequence, evaluates active, reactive and apparent energy and measures distortion and wave-form of measured signals.
