Coach 6 - Measurement

The Coach Measurement Activities are used to collect data from sensors and to display, analyze and process the measurements. A sensor, connected to interface, measures a physical quantity and transforms it into an output voltage, which is read by an interface. The interface, connected to computer, converts an analog voltage signal into a digital signal that is transferred and interpreted by the computer.
Coach collects measurement data according to the measurement settings after pressing the green Start button. In most of Activities the time-based measurement method is used, measurements are stored at regular time intervals according to the sampling frequency. In the event-based measurement method measurements are taken each time a pulse (event) is received on an interface counter input. In the manually triggered measurement the single measurement is taken every time you press a button. This method allows type-in data from keyboard.

During the measurement data can be presented in graphs, tables, meters or displayed as digital values.

In Coach data acquisition is made easy with many features like:

	easy experiment setup
	different measurement methods
	extensive sensor library
	sensor calibration (linear and advanced)
	synchronization of data collection and video capture
