How to return the vernier caliper to the closed position?
When the vernier caliper is closed, what should be done to get it back to the closed position?
If you happen to press the zero button while measuring an object, it will start measuring from that point. However, if you close the jaws after the point where you pressed the zero button, it will read a negative number because you passed the zero point. Simply close the jaws completely, and then press zero again to recalibrate the zero to the closed position.
