The figure named Temperature is shown as follows:
D07
SPR
Temperature
FLAG
Byte 10
It is the Temperature recorded in the interval. The number should be considered as an unsigned 7 bit
integer. In order to avoid negative figure an offset of 40 degrees centigrade is added thus, to get the
correct value of the temperature, the following formula is used: T Centigrade = Temp - 40.
SPR Flag is a reserved one and should be masked (for example Temp & 0x7F).
If, for example, 8 bit figure named Temp is 0x3f (decimal 63) then the temperature will be 23°C
The figure named ALARM is shown as follows:
D07
ALARM ABAT
Byte 11
It is the block of alarms recorded in the interval. Each bit should be considered individually as follows:
•
ABAT When High it flags that the battery voltage was out of the safe limits.
•
ARH When High it flags that the relative humidity is out of working range.
•
ATMP When High it flags that the temperature was out of working range.
•
ALCK When High it flags that the case was unlock.
•
ASENS When High it flags that a Sensor failure was detected.
•
AWRN When High it flags that the RMS field value overcame Warning threshold.
•
AALR When High it flags that the RMS field value overcame Alarm threshold.
The figure named PERTs is shown as follows:
D07
PERTs Reserved
Byte 12
It is the block of every single perturbing occurrence recorded in the interval. Each bit should be
considered individually as follows:
•
TXON When High it flags that RF Modem was ON during sampling.
•
USB When High it flags that the USB connection was ON during sampling.
•
CHG When High it flags that the external Charger was connected by cable during sampling.
•
ETH When High it flags that the Ethernet connection was ON during sampling.

The presence of one of the above flags indicates that the record has been
perturbed by external influence and the result, in the best case, could be
unreliable.
