∗A MODE
The
∗A Mode is used to 1) check the size of Input
Storage, Intermediate Storage, Final Storage,
Program Memory; PakBus and user Settings
memory 2) check the number of bytes remaining in
Flash Program memory; Main Memory, and Label
Memory 3) change the memory allotted to Input
Locations and Settings; and 5) to completely reset
the datalogger.
When
∗A is entered, the first number displayed
is the number of memory locations allocated to
Input Storage. The "A" key is used to advance
through the next 6 windows. Table 1.5-2
describes what the values in the
∗A Mode
represent.
The sizes of Input Storage and Settings Memory
may be altered by keying in the desired value and
entering it by keying "A".

How it works:
The Operating System is loaded into
Flash Memory at the factory. System
Memory is used while the CR10X is
running for calculations, buffering data
and general operating tasks.
Any time a user loads a program into
the datalogger, the program is
compiled in SRAM and stored in the
Active Program areas. If the
datalogger is powered off and then on,
the Active Program is loaded from
Flash and run.
The Active Program is run in SRAM to
maximize speed. The program
accesses Input Storage and
Intermediate Storage and stores data
into Final Storage for later retrieval by
the user.

by 524,288 data values per Mbyte.
