Achievable absolute accuracy with voltage measuring incl. drift correction:
typical ±3 µV
Achievable accuracy for temperature measurement with Pt 100 resistance

rate 1 s, averaging interval 1 min)
without drift correction: ≤ 0.1 °C with ambient temperatures
0 °C...+40 °C
with external drift correction: typical 0.05°C with ambient temperat-
ures
-40 °C...+85 °C
