Collecting data

The data logger writes to data tables based on intervals and conditions set in the CRBasic Campbell Scientific's BASIC-like programming language that supports analog and digital measurements, data processing and analysis routines, hardware control, and many communications protocols. program (see Creating data tables in a program for more information). After the program has been running for enough time to generate data records, data may be collected by using data logger support software LoggerNet, 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 in LoggerNet Setup. Use these instruction or follow the Collect Data Tutorial .

Collecting data using LoggerNet

1. From the LoggerNet Campbell Scientific's data logger support software for programming, communications, and data retrieval between data loggers and a computer. toolbar, click Main and Connect , select the data logger from the Stations list, then Connect .

2. Click Collect Now .

3. After the data is collected, the Data Collection Results window displays the tables collected and where they are stored on the computer.

4. Select a data file, then View File to view the data. See Viewing historic data.

Collecting data using RTDAQ

1. Click Connect on the main RTDAQ Real Time Data Acquisition software for high-speed data acquisition applications. RTDAQ supports a variety of telecommunication options, manual data collection, and extensive data display. It includes Short Cut for creating data logger programs, as well as full-featured program editors. window.

2. Go to the Collect Data tab.

3. Leave the default Collection Options: 

   • Collect Mode should be Data Since Last Collection

   • File Mode should be Append to End of File.

   • File Format should be ASCII Table Data (TOA5)

4. Select the check boxes for tables in the Table Collection list to indicate which tables will be collected.

5. Click Start Collection.

6. After the data is collected, the Data Collection Results window displays the tables collected and where they are stored on the computer.

7. Select a data file, then View File to view the data. See Viewing historic data.

Collecting data using PC400

1. Click Connect on the main PC400 window.

2. Go to the Collect Data tab.

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 for What 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 of PC400 and 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. Click Start Data Collection.

6. After the data is collected, the Data Collection Results window displays the tables collected and where they are stored on the computer.

7. Select a data file, then View File to view the data. See Viewing historic data.
