What does the always remember the zero point, mean? if this is set and zeroed, can i turn it off and not need to re-zero it?

Hi. That means every time you turn on the device, it is absolute zero. You could set the zero point according to your need when you want to measure relative angle. While when you power it off and on again, the zero back to absolute zero. So you could turn it off for anu angle you wish.
