EMA10 - USER MANUAL
Variable reading total harmonic distortion and harmonic components
of voltage and current (option).
6 pages of visualization of THD and harmonic components (up to 31st with
fundamental frequency 50-60Hz) of voltage and current of each line
expressed in numerical and graphic form. Once entering in the harmonic
analyzes page, it may be possible with the right + enter & left + enter keys
to page through the order of the harmonics up to the 31st. The pages show
the histograms, the order of the harmonic and value referred to the
fundamental.

STATUS AND INFORMATION PAGES
The status and/or information pages include:
• the displaying of clock and internal calendar
• the condition of internal RAM memory
• the condition of digital I/O
• warnings
• general info of the instrument
Clock/Calendar
• time format: hours, minutes, second (hh:mm:ss)
• date format: day, month, year (dd/mm/yyyy)
• day of the week
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.
