PZ158AB series DC digital voltmeter and ammeterDetailed product description：

The PZ158AB series DC digital voltage and current meter is a high-precision electronic measuring instrument with a 6 half bit word length, 0.1 μ V voltage resolution, and 0.1 µ A current resolution, equipped with single-chip microcomputer technology. Due to the use of advanced single-chip microcontrollers and precise analog-to-digital conversion technology, this series of instruments can automatically calibrate and effectively filter digital signals at regular intervals, thereby endowing the instruments with extremely stable zero positions, excellent reading linearity, and strong anti-interference capabilities. This series of instruments adopts an eight digit LED display, which is soft and eye-catching. The excellent performance of this series of instruments can play a significant role in fields such as scientific research, industry, agriculture, and national defense. This series of instruments comes with an RS232C interface output, which can be directly connected to a computer with a serial port to form a testing system.
