Collecting data

The data logger writes to data tables based on intervals and conditions set in theClosedCRBasicCampbell Scientific's BASIC-like programming language that supports analog and digital measurements, data processing and analysis routines, hardware control, and many communications protocols.program (seeCreating data tables in a programfor more information). After the program has been running for enough time to generate data records, data may be collected by usingCloseddata logger support softwareLoggerNet, RTDAQ, and PC400 - these Campbell Scientific software applications include at least the following functions: data logger communications, downloading programs, clock setting, and retrieval of measurement data.. During data collection, data is copied to the computer and still remains on the data logger. Collections may be done manually, or automatically through scheduled collections set inLoggerNetSetup. Use these instruction or follow theCollect Data Tutorial.

Collecting data usingLoggerNet

  1. From theClosedLoggerNet坎贝尔科学的数据记录器support software for programming, communications, and data retrieval between data loggers and a computer.toolbar, clickMainandConnect, select the data logger from theStationslist, thenConnect.

  2. ClickCollect Now.

  3. After the data is collected, theData Collection Resultswindow displays the tables collected and where they are stored on the computer.

Collecting data usingPC400

  1. ClickConnecton the mainClosedPC400Free entry-level data logger support software that supports a variety of communications options, manual data collection, and data monitoring displays. Short Cut and CRBasic Editor are included for creating data logger programs. PC400 does not support scheduled data collection or complex communications options such as phone-to-RF.window.

  2. Go to theCollect Datatab.

  3. By default, all output tables set up in the data logger program are selected for collection. Typically, the default tables (DataTableInfo, Public, and Status) are not collected.

  4. Select an option forWhat to Collect. Either option creates a new file if one does not already exist.

    • New data from data logger (Append to data files): This is the default, and most often used option. Collect only the data, in the selected tables, stored since the last data collection from this instance ofPC400and append this data to the end of the existing files on the computer.

    • All data from data logger (Overwrite data files): Collects all of the data in the selected tables and overwrites (or replaces) the existing data files on the computer.

  5. ClickStart Data Collection.

  6. After the data is collected, theData Collection Resultswindow displays the tables collected and where they are stored on the computer.
