Features: 1. High Accuracy & Speed: Measure resistance (0-100Ω) and voltage (-110V to +110V) with 0.5% precision using 1KHZ AC method and four-wire Kelvin clips. 2. Smart Sorting Mode: Set custom voltage/resistance thresholds to instantly classify lithium batteries (soft pack/cylindrical) and screen defective units. 3. Portable & User-Friendly: Compact lightweight design. The 2.8 inch TFT screen offers clear readings, while the portable build and long-lasting battery make it ideal for workshops or on-the-go use. 4. Personalize display colors, shutdown timers, and save calibration values for consistent performance.
