Answer 1

Answer:

Zero error occurs when the measuring instrument registered a reading when there should be none. Note: You can check out Measurement Of Length for information on how to deal with zero error for vernier calipers and micrometer screw gauge. Accuracy is a measure of how close the ..

Answer 2

Any indication that a measuring system gives a false reading when the true value of a measured quantity is zero, e.g. the needle on an ammeter failing to return to zero when no current flows.

A zero error may result in a systematic uncertainty.

e.g. a top-pan balance shows a reading when there is nothing placed on the pan.

e.g. Zack and Zoe are measuring the rebound height of balls dropped onto a bench. Zack's ruler starts at zero, but Zoe's ruler has a 0.5 cm systematic error at both ends: the scale doesn't begin or finish at the ruler's ends. So all her heights are about 0.5 cm too small.
