How to get a good result from the digital tape measure?
1. Choose the right measure mode, pls check the upper left corner for the MODE.
2. The breathe light should be located at the STARTING point and ENDING point exactly.(pictures below)
3. The product is set in 100% accuracy when you got it, but everyones rolling habits or speed is different, this 100% accuracy for you might be just like 90%, pls set your own " accuracy" ---ACC MODE (pictures below)
4. This digital tape measure is fun and needs patience to get the skill of accuracy, if you dont get the correct result, pls check POINT 1 and 2, and if the routing is correct, for instant, you want measure a straight line, but you didnt roll a straight line...the ±0.35inch difference is depends on your rolling.
