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]
Each section is displayed in own sub page.
The page shows the following information:
•
Type of section of memory (for examples samples).
•
Status , "ON" if memory enabled or "OFF" if memory disabled.
•
Record(s) , number of stored events in memory.
Memory (Kb)
•
Available , static memory, expressed in Kb, which is available to store
data for this section.
•
Used , dynamic memory, expressed in Kb, which is used by data already stored (record stored).
•
Free , 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.
Digital I/O
The page shows the "ON" "OFF" status of the digital
inputs and digital outputs.
The symbol "---" indicates that none output/input is
present on the hardware (these are inputs / outputs
optional).
