  • Page 12: Recommended Media

    Racelogic LabSat department. Formatting LabSat3 Media Formatting an SD card or a HDD is important when using LabSat 3, to make sure that the card cluster size is set to an optimum level. Cluster size is the minimum amount of data that can be written in a single operation. So, the larger the cluster size, the better the performance of the card (up to a point).
  • Page 13 If the speed test does not bring up any warnings, this means that the cards read and write speed should be fast enough for use with the LabSat 3. Note, this is not a guarantee that recording a large amount of data will be successful, as the speed test cannot check if the card is fragmented and has other files stored on it.
  • Page 14 • Power Save – When selected, will power down display backlight and internal monitor during recording. • CLK REF ◦ Internal - As the default setting LabSat 3 will use it internal reference clock. ◦ External 10MHz – Allows the user to connect a 10 MHz reference signal on the REF input.
