Morphology
The meaning 'to reset an instrument to zero' is directly derivable from the parts: 'turn' (move/rotate) + 'back' (to a previous/starting position) + 'zero' (the zero mark). The construction 'turn ... to zero' is a straightforward, compositional instruction found across languages and follows normal motion/directional+goal patterns, so a B1 learner who knows the constituents would understand it.
Etymology
The phrase turn back to zero comes from the image of a dial or counter that you turn by hand so the pointer goes back to the start at zero. So it means 'to reset' an instrument or gauge to its starting point.
