Or is it non-adjustable?** A: I don’t think or I don’t know of a feature to calibrate the wrench. On a normal car it is 100lbs. And, it varies depending on make and vehicle. You will have to google it. But, 100lbs it is tight. **Q: Does this does angle measurement for engine head bolts ??** A: When you power it on, you need to leave it on a flat surface when you see 00000. It is calibrating the Angle accelerometer. If you keep moving it around, it will take forever to boot. **Q: What size battery ?** A: 2 AA batteries ## Customer Reviews ### ⭐⭐⭐⭐⭐ Buy it. *by N***C on May 10, 2017* ### ⭐⭐⭐⭐⭐ Precise *by D***N on June 15, 2025* ### ⭐ Error message 1 week after use. “Err110” message.
