6.- DATA COLLECTION INTO MEMORY
6.1.- Characteristics
The CVM-BDM power meter is equipped with an internal memory to store
some all the electrical parameters measured or calculated by the analyzer.
Data collection into memory is automatically carried out every user-defined
period. Either this recording period as the parameters to be saved are defined
through a PC set.
#
Point to consider
The internal memory is a rotary type memory:
Once the internal memory of
the
CVM-BDM
is full, newest values will replace oldest ones.
6.2.- File types
The
CVM-BDM
executes the integration of all measured values, calculates the
average, maximum and minimum value of the defined period, and collects data into
memory according to the set recording period (the available period can be set from 1
s to 240 min (4 hours )).
Following files are saved into memory
:
Extension

size
DATA saved into the file
xx.STD
variable
Only saves into memory the selected parameters:
instantaneous, maximum and or minimum values.
Parameter selection is done via PC (maximum 130
parameters).
xx.EVE
6 bytes
Power ON - Power OFF (DATE - TIME):
date/time of voltage supply loss, and restoring date/time
-
The CVM-BDM... calculates every second values of all parameters, regardless
its configuration.
-
Internal values in the internal memory can be retrieved from a PC, via RS-485.
