Measuring principle
Conversion and cycle time:
Integration time can be assigned parameters
•
•
•
•
Noise suppression for f = n x (f1 ± 0.5%),
(f1 = interference frequency)
•
•
Crosstalk between the inputs
Operational limit

(operational limit at 25°C)
Temperature error (with reference to the input
range)
Linearity error (with reference to the input range)
Repeatability
(in steady state at 25°C with reference to input
range)
