When inserting Measurements, users must always consider the location where that Measurement is requested. Inside a Measurement, whether Analog or Discrete, users can insert one or more Measurement Sources, indicating how information is received by an application. These Measurement Sources can be input ones or from a Hydraulic Study. To insert a Measurement Source, right-click a Measurement, select the Add option and then the type of Measurement Source, according to the next image.

By default, each Measurement is created containing an Operator-type Measurement Source. For input Measurement Sources, except for the Operator-type Source, users must configure which variable provides their values. This configuration is performed in the Tag property of an Analog or Discrete Measurement.
