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.
good accuracy good precision
Accuracy is a measure of how close the results of an experiment agree with the true value.
When accurate, small systematic error
accuracy and precision
Precision is a measure of how close the results of an experiment agree with each other. It is a measure of how reproducible the results are.
small uncertainty, increase precision, small random error.
A scalar quantity is a physical quantity with magnitude only.
A vector quantity is a physical quantity that has both magnitude and direction.

zero is also a reading, its not right to say ‘when there is none’

Although zero is a number, the instrument registered a zero for the quantity being measured
