¹ ThetemperaturecurvesfortheNTC10karenotstandardizedandmaybedi󰀨erentforeachmanufacturer.
For this reason, the curves can be loaded by the user program using the linearization FBox. The curve of
theNTC10kfromProdualisavailableinaCSVleandcanbedownloadedfromtheSupportWebsite.

Withaninputconguredin“Diode0…5000mV”,itispossibletouseintegrated
circuit temperature sensors operating as a 2-terminal zener. A typical sensor for
this measurement is the LM235 for example.
