Electrical conductivities above 23.1 are truncated to this maxi-
mum value. The 5TE uses the
σ
Raw
value of 1023 to indicate
the electrical conductivity portion of the sensor is not working
as expected.
Temperature
The raw temperature value, (T
Raw
), is valid in the range 0 to
1022. The 5TE uses a compression algorithm to extend the
range of temperatures that can be represented by a 10-bit
value. The sensor sends temperature with 1/10 of a degree
Celsius resolution for the range -40 to 50.0°C. For the range
50.5 to 111.0 the sensor sends temperature with a 1/2 of a
degree resolution. Temperatures outside this range are trun-
cated to the maximum or minimum values as appropriate.
The 5TE uses the T
Raw
value of 1023 to indicate the tempera-
ture portion of the sensor is not working as expected.
