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 further
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.
Display in ° C, ° F and K.
It is possible, except for the thermocouple B, to choose by programming the position of the cold junction with 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 value displayed L and not its absolute value.
Temperature coefficient: < 10 % of the accuracy/° C.
The above accuracy is given for a 4-wire connection to the temperature measurer in continuous mode and for a 1 mA
measurement current for PT50, PT100, NI100, NI120, CU10 and CU50 probes and 0.1 mA for PT200, PT500 and PT1000
probes. For measurement currents included in the measurement range (0.1 mA-1 mA), the constant accuracy term for 1
year has to be multiplied by 2 (e.g., PT100 at 0.1 mA, accuracy is 0.006% + 0.07° C).
Taking into account, also, the intrinsic error of the temperature sensor used and its conditions of use.
