Memory
The measurements are stored in the memory with a sliding window (older data is deleted and replacedby the more recent data).
The memory allows you to to read data preceding the current data with a time which varies depending on the amount of data stored and the
data backup interval
TAB.1
Shows the amount of data stored according to the type chosen.
TAB.2
Indicates the depth of data reading (expressed in hours) depending on the type of backup selected and the selected backup
interval, e.g. data type 0 interval 2 min. You will be able to access stored data up to the previous 1092 hours.
TAB. 3 Indicates the reading depth of the energy data and average power (expressed in days and depending on the selected range, e.g. 5 min
will have 444 days (14 months) back up.
Energy measurements are stored every 5-10-15 min / programmable
● = Data stored
✘ = Data stored on request.

FORMULA FOR TYPE 4 DATA
For type 4 data, you can obtain an estimate of the backup depth with the following formula:
Floor = Function which returns the whole part
Time
= Time interval in seconds
sec
Rlength = Record lenght in byte e.g.: 3V + 3I = 24 +
