Bahwan Engineering Refrigeration and Air Conditioning Mechanic Interview Questions and Answers

Height of instrument is the vertical distance between the instrument and a reference point on the ground.

• It is used in surveying to determine the elevation of points on the ground.

• It is measured using a leveling instrument such as a level or a theodolite.

• The height of instrument is calculated by subtracting the height of the reference point from the height of the instrument.

• It is important to maintain a consistent heig...read more
