Measurements are calibrated over operating temperature and voltage and should be interpreted as defined
below. Alarm and warning threshold values should be interpreted in the same manner as real time 16 bit data.
Internally measured temperature
The temperature is represented as a 16 bit signed two’s complement value in increments of 1/256°C, yielding
a total range of ‐128°C to +128°C. The measured range is limited to the operating recommended conditions.
To convert a 16 bit digital value in Celsius, take directly the 16‐bit value and divide it by 256°C. If the result is
greater or equal to 128, subtract 256 from the result.

Internally measured supply voltage
The voltage is represented as a 16 bit unsigned integer with the voltage defined as the full 16 bit value (0 –
65535) with LSB equal to 100 μVolt, yielding a total range of 0 to +6.55 Volts. The measured range is limited to
the operating recommended conditions. To convert a 16 bit digital value in Volt, take directly the 16‐bit value
and multiply it by 100 μVolt.

Alarms and Warnings
An Alarm or a Warning flag is set if the measured temperature or voltage exceed the corresponding Alarm or
Warning threshold value.
