.3 “Previous Count” button

Whenever samples are counted, results are automatically saved to the internal memory of the

instrument. These data can be exported as a “.CSV” file to the USB drive for further analysis.

.3.1 Pressing the “Previous Count” button on the left side of the “Review” menu will bring up a new

window. The “Previous Count” window contains up to 1,000 previous counting results that have been

saved in the memory of LUNA-FL.
