Table 2: Inputs specifications for each mode
The measuring current was chosen to be the best compromise between the reso-
lution and the sensors self-heating effect, which is negligible for most of the sen -
sors and applications. Even in bad measuring conditions with Pt/Ni1000 sensors
with a low thermal coupling as 4 mW/K, the maximal error produced by the sen-
sors self-heating is lower than 0.3°C.
