If input measured quantity to the instrument is steadily increased the output reading varies in the manner shown in curve A . Steering Committee Meeting. October 10, 2011. Background:. Order Signed Sept. 21, 2011. First Annual Meeting to be held Nov. 7, 2011. Ground Water Rights Included. All irrigation ground water rights > ½ acre. ABE425 Engineering Measurement Systems. Agenda. Null methods (calibration and highly accurate measurements). DC bridges (Resistance measurement). Wheatstone. Capacitor and inductance (coil) models. AC bridges (Inductance / capacitance measurement). These are RATIOS. A measured distance on a map represents a measured distance on the ground.. Examples. 1:25 000 means 1 cm on the map is equal to 25 000cm on the ground. 1:50 000 means 1 cm on the map is equal to 50 000cm on the ground.. Speaker: Yee Wei Law. Collaborators: . Umith. .
