When the Results Manager receives the measurements during testing, it will compare the value to the Grading Conditions and determine if the value \u2018Passes\u2019 or \u2018Fails.\u2019<\/p>\r\n\r\n<p><span style=\"font-size:larger;\"><strong>Results Destinations<\/strong><\/span><\/p>\r\n\r\n<p>Results Destinations are constructs set up to export the data generated by the Results Manager. A Results Destination is a consumer which receives data from the producer, the Results Manager. Results Destinations handle formatting and delivery of the data to a desired location. Examples of past Results Destinations include:<\/p>\r\n\r\n<ul class=\"wp-block-list\">\r\n <li>Web database via RESTful API<\/li>\r\n <li>Text, CSV, and TDMS files<\/li>\r\n <li>Live user interface display<\/li>\r\n<\/ul>\r\n\r\n<p>The Results Manager can write to multiple Results Destinations at once, allowing for parallel logging of any individual Measurement (i.e., logging a measurement to a text file and a database concurrently). In the background, the Results Manager handles distributing data to each configured Results Destination to keep the user\u2019s code clean and the Results Manager API simple.<\/p>\r\n\r\n<p>Creating new Results Destinations is simple and follows the same LabVIEW Object-Oriented approach as a measurement: the user overrides the _Results Destination class and implements the data formatting and exporting to fit their application needs.<\/p>\r\n\r\n<p>These features are part of a powerful suite of tools called the DMC Flex Framework.\u00a0<a href=\"https:\/\/www.dmcinfo.com\/services\/test-and-measurement-automation\/labview-programming\/flex-framework\">Find out more about all of these tools here<\/a>.<\/p>\r\n\r\n<p><strong>Learn more about DMC&#8217;s <a href=\"\/services\/test-and-measurement-automation\/labview-programming\">LabVIEW Programming Expertise<\/a>.<\/strong><\/p>\r\n","protected":false},"excerpt":{"rendered":"<p>Results Manager Structure The goal of the Results Manager is to enable easy creation and logging of test information in a variety of formats.
