Maximum measurement
error for current inputs and
outputs
Typical measured errors:
< 20 μA (with current values < 4 mA)
< 50 μA (with current values 4 to 20 mA)
at 25 °C (77° F) in each case
Additional measured error depending on the temperature:
< 1.5 μA/K
LOD (limit of detection) 0.5 µg/l (ppb)
Repeatability
4)
CA80SI-**AH*: ± 0.5 µg/l (ppb) or ± 1 % of measured value
CA80SI-**AJ*: ± 1 % of the measured value
