When a test instrument is calibrated what improves

The accuracy of all measuring devices degrade over time. This is typically caused by normal wear and tear. However, changes in accuracy can also be caused by electric or mechanical shock or a hazardous manufacturing environment (ex., oils, metal chips etc.). Depending on the type of the instrument and the environment in which it is being used, it may degrade very quickly or over a long period of time. The bottom line is that, calibration improves the accuracy of the measuring device.

Explanation:

cad, or computer-aided design and drafting (cadd), is a software for design and technical documentation, which is an automated process as opposed to the manual drawing of plans. this gives a person an advance in making plans as an architect in a short period of time. one who can render plans through this software will gain a skill that is better than one who makes plans manually. this is a skill some companies look for in an employee.
