2-3-3 DATA LOGGING
The Data Logging screen shown on page 13 is presented as a result of selecting the Data Logging tab.
Logging Data
To start logging data:
• Set Wireless Remote Display to “Passive” mode. Mode selection is available from MAIN MENU > Device Settings > Wireless Settings > Mode.
• Select the Data Logging tab from the main display screen.
• Select or create a folder where the data files will be stored by clicking on the folder icon next to the text box titled “Folder for log files” As log files are
created DataLogger will place the files in this folder. It may be most convenient to create folder on computer Desktop.
• Set the sample interval in seconds in the text box labeled “Write to file every _______second.” If “0” is entered in the text box data will be written to the
file as soon as data is available from Skystream. This may be multiple times a second.
• Create the file name and format. The file name and format controls the size of the file and how often a new data file is placed in the Log File Folder
created previously. See “Creating File Names, File Format” below.
• Select “Start auto logging” to start collecting data.
To end logging data:
• Depress oval shaped “Start auto logging” button on data logging screen a second time to stop data logging. Green “light” on switch will turn off.
Creating File Names, File Format
A new file is created and the old file moved to the file Folder specified on the Data Logging page. A new file is created on a time basis using special
characters in the file name. The special characters and associated time intervals are listed below.
%Y = Year %H = hour %m = Month %M = minute %d = day
For example if the file string is specified as “Skystream%H” a new file is created every hour since the smallest time interval character is %H – an hour.
The time interval is based on the PC clock running the DataLogger software. Also be aware that in the above case only 24 files will be created since
the first file will be appended (data will be added to end of file) the next day at the same hour. For this reason it is recommended to use the complete
YearMonthDay_Hour code in most cases.
File sizes are not limited. If a time interval of a year is selected and the sample rate is set to one second expect a very large file. Data is stored as comma
separated data and is readily imported into spreadsheet programs such as Excel for analysis.
2-3-4 TURBINE SETUP
Use of the Turbine Setup Screen is described in detail in Section THREE - Setting up for Battery Charging.
