The KDZD2020 is a portable, handheld dual-clamp phase volt-ammeter designed for field power testing. It features a 3.2-inch color TFT display and intuitive GUI, supporting measurement of AC voltage (0~AC600V), current (10A~2000A), phase (-180°~+180°), and power parameters. With built-in data storage (10000 records) and USB export, it enables efficient analysis of transformer wiring, phase sequence, and relay protection systems. Its lightweight design and long-lasting lithium battery make it ideal for field use.
