1. Purpose: PZ96-A3V3 digital display instrument is a new generation programmable intelligent voltage and current meter, which is used for real-time measurement and display of AC voltage and current in electrical circuits. It has the characteristics of high precision, good stability, long-term operation without calibration, and can set parameters on site through panel buttons. It is an ideal replacement product for original pointer instruments or ordinary digital instruments.

2. Technical features: This series of instruments adopts large-scale integrated circuits and high-performance single-chip microprocessors, and is designed in a modular manner using digital signal processing technology and SMT process. The instrument keyboard can easily set the transformer magnification of the instrument. The internal calibration potentiometer of the instrument has been eliminated, and software calibration has been adopted for production. The modular and universal design significantly reduces the production cost of the instrument, making this series of instruments have a high cost-effectiveness.
