How are the CI-202 measurements stored?

All measurements are associated with a file name. The user may create, delete, truncate, or close any file. If all files have been deleted from the device, the Measurement Menu will temporarily be hidden. To allow measurements, just create a new file. Follow the instructions found on page 10 of the User Manual for further details. All measurements are stored as 16-byte records in a circular buffer in serial flash memory. If record to be stored crosses a page boundary, that page will be automatically erased and then the record will be written to flash. Page size is 256 bytes with current hardware version. This approach gives the user the illusion of infinite storage size, and flash wear out is minimized. This approach also means that the user needs to download important data to a computer before it gets overwritten.
