Single Phase Multifunction Reference Energy Meter (0.05/0.1) HC3101B

HC3101B single-phase reference standard meter adopts the latest international digital electronic technology, with 32-bit ARM high-speed processor as the core, plus various advanced methods such as transformer active compensation technology, 16-bit high-speed AD conversion technology, and digital compensation technology. The instrument achieves a high accuracy better than the relative error of 0.05% RD.

HC3101B single-phase reference standard meter can simultaneously measure and display voltage (V), current (A), active power (W), reactive power (Var), frequency (Hz), power factor (PF), phase angle (θ), Apparent power (VA) and other electrical quantities; perform harmonic analysis on voltage and current input signals, calculate and display harmonic content, initial phase angle, power, etc.; can also output electrical energy pulses (active energy, reactive energy, harmonic energy,etc.) to facilitate inspection or provide standard pulses for other devices. The display adopts liquid crystal display, so the picture is clear, the operation is simple, and the function setting is convenient. It is an intelligent power measuring instrument

HC3101B single-phase reference standard meter has a wide range of signal input and auxiliary power supply, which can be applied to various systems and environments.The meter is equipped with a serial port (RS232), to allow connection and control on PC and all the testing parameters also could be acquired from PC as auto-measurement.
