Final answer:
Adding positive and negative dial indicator readings can be used as 'total indicator readings' to measure displacement or deviation from a reference point.
Explanation:
Adding positive and negative dial indicator readings can be used as total indicator readings. When we add the positive and negative values of the dial indicator readings, the resulting sum will give us the total displacement or deviation from a reference point. This can be useful in various applications, such as measuring the distance traveled by an object or the change in position of a machine part.
