ACDelco ARM303-4A-340 1/2" Heavy Duty Digital Torque Wrench with Buzzer and LED Flash Notification - ISO 6789 Standard with Certificate of Calibration

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?

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 ??

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.
