Features: Up to Six-Phase Input on One Unit. Synchronized Measurements Between Two Units Wide Current Input Ranges Data Storing as Fast as 50 ms (20 Times per Second) High Precision and Wide Bandwidth Increased Assured-Accuracy Range for High-Precision Measurements A Variety of Display Formats Display Harmonic Data as Bar Graphs, Vectors, and Lists Built-in Printer (Optional) A Variety of Interfaces (Optional) Integration Function Capable of Handling Rapid Changes in Input Signal Other Special Features The WT1600 is power meter designed for measurement of extremely small currents in energy-saving equipment, as well as measurement of large currents for evaluating large-sized loads. The WT1600 works with voltages ranging from 1.5 V up to 1000 V, supporting a wide range of applications. Because it can accept signal inputs for up to six phases, a signal WT1600 unit can measure I/O signals on inverters.
