1)

Format of the input data (

13.1−6).

2)

Tolerance of the input range at an ambient temperature of 25 °C and 15 conversions/s. Sensor inaccuracies were
not considered.

3)

Transition resistances on contacts and cable resistances were not taken into consideration.

4)

Cold spot compensation must be effected externally.

5)

The cold spot must be compensated internally. The temperature of the terminal is taken into consideration.
Connect the conductors of the thermoelements directly to the terminal; if necessary, operate with thermoelement
extension cables.
