The Memory Usage tab shows the capacity of the FCO770’s data logging repository
and the current usage. All data written to the repository is compressed to save space.
•
DATA units are consumed at the rate of approximately 1 per single test and less for
products containing multiple steps.
•
GRAPH units are consumed at the rate of approximately 1.5 per single test and less
for products containing multiple steps.
•
The Max Datalog memory reserved for storing graphs: setting can be adjusted
from 0 to 100% . This is the percentage of repository space you are allowing for
storing Graph plots. Graphs are more memory consuming and may not be considered
essential when data logging, and so the user can choose a threshold at which the
FCO770 will reserve for graphs should its memory become full.
