- 【4-Digit High-Precision Display】0.001V / 0.001A High-Resolution Four-Digit Display — Simultaneously reads and controls voltage and current with laboratory-grade accuracy. The encoder knob allows for ultra-fine stepless adjustment — ideal for electronics repair, PCB testing, battery charging, and DIY projects.
- 【4 Groups of Storage Memories】Save up to 4 custom voltage/current settings (e.g., 5V/2A, 12V/1A) and recall them with one click. Eliminates repetitive adjustments for frequent tasks, boosting efficiency in production lines, DIY projects, or daily lab use.
- 【Precision Encoder Adjustment】Adopts a high-precision rotary encoder for smooth and accurate adjustment from 0 to 9 in sequence, allowing fine-tuning and quick setting of voltage and current parameters with better hand feel and higher efficiency than traditional buttons.
