As you move the slider to the right, towards Chart, you will notice the allocated internal flash
memory space for the chart data will increase in the bar above the slider. As you move the
slider to the left, towards Log, you will notice an increase in the internal flash memory for the
Log data in the bar above the slider.
The Total Available Space bar also contains minimum chart and log memory allocation, this
is shown in the hatched areas at both ends of the bar. You cannot use this reserved internal
flash memory.
The Reset button will return the slider and the memory allocation to its original position when
you entered the Storage Bias screen.
The screen also shows chart information regarding how many pens are currently enabled
and how much time it will take to fill the chart memory depending on the chart speeds se-
lected. When you move the slider to increase the chart memory the amount of time to fill the
chart memory will also increase. If you decrease the chart memory, thus increasing the log
memory, the amount of time to fill the chart memory, ie. chart history, will decrease accord-
ingly. Note that as you allocate more chart memory the recorder gives preference to medium
and slower chart speeds.
The log information displays how many pens are currently set for logging/recording. The
shortest pen means the pen that will take the shortest amount of time to fill it's part of the
log memory before it starts recycling, that is, overwriting the oldest data with the newest. The
longest pen is the pen that will take the longest amount of time to fill it's part of the log mem-
ory before it starts recycling. The recorder will, where possible, balance the times so the
shortest and longest pens fill the log memory at approximately the same time. Depending
on the different log rates, the allocation of memory will vary per pen.
When the configuration is complete select the Finish button to Commit, Discard or Commit
Later. Select the Back button to return to the previous menu.

NOTICE
Because pens only begin to use extra memory when it is required there will be some
delay in how quickly other screens update the memory allocation information. Eg. the
Recording screen will adjust "Export Required In" time depending on chart speeds,
pens rate and how far the slider is moved.
