product description

This device is a 0.05 (0.1) single-phase AC and DC standard device designed in accordance with the requirements of the Verification Regulation JJG124-2005 "Verification Regulations for Ammeters, Voltmeters, Power Meters and Resistance Meters".

The signal part of the source adopts DSP and 16-bit high-speed digital-to-analog converter to form a controllable sine wave and distortion wave signal source.

The display adopts a standard graphic 240×128 dot matrix LCD monochrome screen, and the chart characters are displayed clearly.

The circuit design is perfect, the operation is reliable, and the operation is convenient.
