Condition internal RAM memory
4 pages (selectable with “LEFT” and “RIGHT” keys) of information on condition internal RAM memory.
The internal memory is divided in 4 sections:
•
storage values average powers [Avg. Powers]
•
storage values relative minimum and maximum [Min/Max]
•
storage values harmonic components [Harmonics]
•
storage values samples [Samples]
The page shows the following information:
•
Status (S)
, "On" if memory enabled or "Off" if memory disabled.
•
Record (Rec.)
, number of stored events in memory.
Memory (Kb)
•
Used (U)
, dynamic memory, expressed in Kb, which is used by
data already stored (record stored).
•
Free (F)
, dynamic memory, expressed in Kb, which is free to store data.
Used
&
Free
memory are working together, blocks of memory are transferred from
Free
memory to
Used
memory in order to store the values on the RAM of the instrument. Initially the available memory
will be totally free but at own exhaustion it will be totally used.
These information are very important to avoid to delete stored data, to choose how to storage the data
on the basis of available memory.
The storage is organized as FIFO (first in first out) type memory. When the memory is full, older data
will be overwritten by new data.
The data downloaded on PC using NRG software or communication protocol does not come deleted
and for this reason it’s possible to recover them using the function of communication protocol.
Warning. If any of the above mentioned parameters has been enabled for storage, by exiting the setup
menu a brief message will appear, asking the operator to erase all the previous stored data, in the
memory, in order to enable a new recording campaign at empty memory with no residual information.
