Condition internal RAM memory
5 pages (selectable with “LEFT” and “RIGHT” keys) of information on
condition internal RAM memory.
The internal memory is divided in 5 sections:
•
storage values average powers [Avg. Powers]
•
storage values relative minimum and maximum [Min/Max]
•
storage values harmonic components [Harmonics]
•
storage values samples [Samples]
•
storage energies and generic counters [Counters]
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 – Hour Counter
The Digital I/O pages show the status of the digital
inputs and outputs, for each is indicated if the contact is
closed (ON) or opened (OFF). The symbol "---" indicates
that none output/input is present on the hardware (these
are inputs / outputs optional).
On the page
Hour Counter is showed the incremental
time of activation outputs.
