The figure named PROC is shown as follows:
Reserved
D07
MISC
Byte 13
This figure ( PROC ) reports how the process took place in the period.
•
RMS (D05) flags whether the averaging has been made linear mean (AVG) or Root Mean
Square(RMS). If the Flag is 1 then the RMS was taken otherwise was AVG.
•
AVGPeriod is a 4 bit unsigned integer which shows the interval (expressed in minute) related to
the time span used to get the average (RMS or AVG).
The figure named MONTHS is shown as follows:
Reserved
D07
MONTHS
Byte 14
MONTHS is a 7 bit unsigned integer which indicates how many months have been elapsed since 1
January 2014. Being the range limited to 127 the overlapping period is more than 10 years.
D07 is reserved and should be masked.
If, for example, MONTHS is 0x10 then the meaning will be:
•
MONTHS =16 (May 2015). Indeed 0x10 = 16 =12 + 4
The figure named DateTime is shown as follows:
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
DateTime
Byte 15/16
DateTime should be considered as a little-endian unsigned 16 bit integer and indicates how many
minutes have been elapsed since the beginning of the current month (previous MONTHS data).
If, for example, DateTime is 0x95AE (decimal 38318) then the record will be related to the 27
month at 14:38.
Indeed :
Day = 1 +Int(DateTime / 1440) = 1 +Int ( 38318 / 1440 ) = 27
Hour = Int((DateTime Mod (1440)) / 60) = Int ( ( 38318 Mod (1440 ) ) / 60 ) = 14
Minute = (DateTime Mod (1440)) Mod 60)= ( 38318 Mod ( 1440 ) ) Mod 60 ) = 38
Merging the data with MONTHS we can get the full date of acquisition which is 14:38 27/05/2015
