An engineer sets the pressure in a supply tank using a very accurate manometer as a guide and then reads the output of a 20-psig pressure gauge attached to the tank as 10.2psig. Sometime later she repeats the procedure and obtains values of 10.4 and 10.3 psig. Discuss the following gauge properties: (a) Precision (b) Accuracy (c) Resolution (d) Repeatability Express these answers on a percentage of full-scale basis.
