The precision is guaranteed for a reference junction temperature of 0°C.
When using the internal reference junction (except couple B) add an additional uncertainty of 0.2°C at 0°C. For other
temperatures, account must be taken of the sensitivity of the thermocouple to the temperature (T) in question, giving an
additional uncertainty of 0.2°C * S(0°C)/S(T).
Temperature coefficient: < 10 % of the accuracy/°C from 0°C to +18°C and from +28°C to +50°C.
Display in °C, °F and K.
It is possible, thermocouple B excepted, to choose the location of the cold junction by programming from the keyboard:
external at 0°C,
internal (compensation for the temperature of the terminals of the unit).
by programming the temperature.

For negative temperatures, use the displayed value L and not its absolute value.
Temperature coefficient: < 10 % of the accuracy/°C from 0°C to +18°C and from +28°C to +50°C.
The above accuracy is given for 4 wire connection of the temperature sensor ("Y shaped lug" connection).
The above accuracy takes into account the intrinsic error of the temperature sensor used and its conditions of use.
