Memory Size
The total amount of SRAM in the datalogger.
Memory Free
The amount of unallocated memory on the CPU (SRAM).
All free memory may not be available for data tables. As
memory is allocated and freed, holes of unallocated
memory, which are unusable for final storage, may be
created.
Errors
Watchdog Errors
The number of internal watchdog errors that have occurred
while running the current program.
Skipped Records
The number of records that have been skipped for a given
table. Skipped records are normally caused by skipped
scans.
Low 12V Count
The number of occurrences of the 12VLow signal being
asserted. When this condition is detected, the datalogger
ceases measurements and goes into a low power mode until
proper system voltage is restored.
Low 5V Count
The number of occurrences of the 5VExtLow signal being
asserted.
