For negative temperatures, use the value displayed L and not its absolute value.
Temperature coefficient: < 10 % of precision/°C from 0°C to 18°C and from 28°C to 50 °C.
The above precision is given for a 4-wire connection to the temperature sensor.
You should also take into consideration the actual error of the temperature sensor used, as well as the conditions of its
setup.
