¹) For thermocouples, the full measurement range is offered. The specifications of resolution and accu
-
racy are given for temperatures higher than -150°C. For lower temperatures than -150°C, the char
-
acteristics of thermocouples become worse. If thermocouples are used in this very low temperature
range, the tolerance should be calculated using the tolerance specifications for the ±75 mV range and
the thermocouple characteristic.
