Note
Basic error with an integration time of 2.5 ms.
With an integration time of 2.5
ms, the measured value is changed by the following values
based on the additionally obtained basic error and noise:
•
with "voltage", "current" and "resistance" by ±0.1 %
•
with "Thermal resistor Pt 100 Standard" by ±0.4 K
•
with "Thermal resistor Pt 100 Climatic" by ±0.3 K
•
with "Thermal resistor Ni 100 Standard" by ±0.2 K
•
with "Thermal resistor Ni 100 Climatic" by ±0.1 K
