## Questions & Answers

**Q: Can you have a set torque of say 30 ftlbs and then have another saved setting of 70* at the same time?**
A: Yes you can

**Q: If it is shown that the torque readings are not correct, can the torque calibration be adjusted by the owner of the wrench? 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
