6.0 Data Management Data management is the collecting and saving of data from your test runs and the reporting of result using printouts. L3 Series software is designed to allow data to be managed easily. Files of raw data from a test run or files of your results are saved in a .csv format. This makes it easy to convert into Microsoft ® Excel ® , Word ® or Access ® for advanced data management and reporting, and the ability to interface your data and result into 3rd-party statistical process control applications. L3 Series systems can save up to 1,000,000 rows of data for a test run. The maximum test run duration is 24 hours. This would include a cyclic test or a creep test. Therefore, the maximum sampling rate for a 24 hour test is 10Hz (864,000 rows). 6.1 Post Test Setup The Post Test stage has functions that may be used to manage your results and data: • Export Raw • Export Results • Print Results • Runs Limit The Pre Test stage also effects how data is collected. The Sampling Rate (Hz) is used to specify the frequency that data is collected during a test run. The Sampling Rate (Hz) may be set from 1 to 2000 Hz.
Post Test Stage
6.1.1 Export Raw Data The Export Raw option lets you specify how your raw data for a test run is saved. You have the following options: • No • Overwrite • Auto Number When Export Raw = No, data is not exported to the Exports sub- directory. No .csv file of your raw data for a test run is saved. When Export Raw = Overwrite, a .csv file is created for each test run. The .csv file has a row based on the Sampling Rate that was setup in Pre Test for this test setup. “Overwrite” means that the current .csv file for this test is over-written with new data at the completion of each test run, e.g. there is only one (1) .csv file for this test. The .csv file is named [Test Name]_RawData and is saved to the Metlogix/Exports directory. NOTE When Overwrite is selected, there is always only one (1) .csv file for the test setup. At the completion of a test run, the data from the previous run is replaced by the new data.

Specify the data acquisition rate. 100 Hz is 100 data samples per second.
