If you have other (non-data) files you want to keep, copy them to the internal drive, or to another Flashcard for temporary storage (don't forget to copy them back and delete them immediately afterwards), alternatively copy them to your PC using RCOM or SLINK, or the PsiWin program if you have it.

♦On the Workabout, exit from SunData (if necessary) by pressing ∪ +X.

♦In the System Screen, press Menu, Disk, Format disk, Enter.

Then follow the instructions and prompts carefully.

Warning! Reformatting is an irrevocable process - you will get on-screen warnings that files will be deleted. Also, do not format the Internal drive - you will lose your SunData program!

Data memory management

The memory space taken up by a given number of readings can't be specified exactly because it depends on how many notes have been included, the number of data groups used, whether the file is a .PRN or a .CSV file, and so on. The following estimates will however give you a useful guide when planning experiments.

For the standard 256K Flashcard, about 2500-3000 readings can be stored in the LAI and PAR modes. This reduces to about 400-500 in the All mode, which retains the 64 individual diode values for each reading. The optional 1 Mb Flashcard can accommodate about four times these amounts.

You can check the available memory space on your Flashcard from the Psion system menus as indicated in the previous paragraph. Bear in mind the note about creating space on the Flashcard.

Warning! Don't be tempted to store data files in the internal memory even though it may appear to have plenty of free space. The SunData program uses a lot of this space when running, and will refuse to run without it.

Configuration and data file handling

Opening and closing files in the SunData programs follows a somewhat different routine from that used by applications run in desktop PCs because of the Workabout's Solid State Disks.

Two sorts of files are involved: data files which are used for storing measurements made by the SunScan; and configuration files, in which you can retain the settings of different sites and experiments.

SunData Configuration files

Configuration files contain information on the state of the SunData program, which includes the following Settings menu and readings information:

•SunScan probe and External sensor settings

•Site and local time details.

•Leaf constants (Absorption and leaf angle distribution parameters).

•Display mode for readings (LAI, PAR or All).

•Title and reading Group names.

•The Plot and Sample numbers of the last reading taken.

•The filename, subdirectory and file type (.PRN or .CSV) for data storage.
