Thermocouples
shortest span: 100°C
Measurement accuracy:
±0.1% referred to range limits. On Type J
this applies only from –200 °C upwards, on
Type U and T only from –150 °C, on Type K
only from –80 °C and on Types E und N only
from –100 °C upwards.
shortest span: 500 °C
Measurement accuracy:
±0.15% referred to range limits. On Type B
this applies only from 400 °C upwards, on
Types S and R only from 0 °C upwards.
Within the range limits the start and end of
range can be freely programmed in 0.1°C
steps.
