Using the Miniware DT71 Digital Tweezers is a breeze. First, make sure the tweezers are fully charged. You can charge them using the 3.5mm audio power interface for about 2 hours. Once charged, the tweezers can operate continuously for up to 10 hours. To start using, simply touch the hidden touch button. The smart gesture recognition feature will detect whether you're using your left or right hand and adjust the screen display accordingly. The 360° rotatable OLED screen makes it easy to read the measurements from any angle. When taking measurements, choose the appropriate gold - plated tweezer tip for your specific needs to ensure high accuracy. Be careful when handling the test arms as they use magnetic elasticity for easy clipping. For maintenance, keep the tweezers clean and dry. If you need to replace parts like the tweezer tips or test arms, it's easy due to the unique ternary structure. Always refer to the Miniware DT71 Manual for full specifications and safety instructions.
