SD Card Data Structure
1. When the SD card is first inserted into the datalogger the folder PSB01 is created on the
card.
2. The first datalogging session will then create a file PSB 01001.xls. All data will be saved to
this file until the number of columns reaches 30,000.
3. After 30,000 columns, a new file (PSB01002.xls) is created. This is repeated every 30,000
columns until PSB01099.xls. At this point a new folder, PSB02 is created and the process is
repeated; PSB10 is the final folder.
Transferring Data to a PC
1. Remove the memory card from the datalogger and plug it into the SD card slot on the PC.
For PCs that do not include an SD card reader, external SD card readers are generally
available and can be connected to the PC's USB jack.
2. Launch Excel® and open the data file on the memory card from within the spreadsheet
program. The file will appear similar to the one shown below.
