Review on 📏 Accurate and Reliable VIGRUE Protection Millimeter Conversion Measurement Tool by Born Waheed

Easily switch between imperial and metric units. The LCD screen displays large, easy-to-read numbers, unlike a traditional caliper. Accuracy 0.0005 inches, 0.01 mm, that's enough for me. Comes with two CR2032, very convenient for me. In fact, the caliper only needs one battery. The quality and size suit me too. But I didn't understand how to use the data output jack. The user manual only mentions the data-out port but doesn't tell me how to use it. It will be a bonus if I can find out.
