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) 0.06mg/l (ppm) N

Repeatability
4)
Measuring range Repeatability
0 to 10 mg/l (ppm) N 0.06 mg/l (ppm) N or 3 % of the measured value
0 to 20 mg/l (ppm) N 0.12 mg/l (ppm) N or 3 % of the measured value
0 to 50 mg/l (ppm) N 0.3 mg/l (ppm) N or 3 % of the measured value
0 to 100 mg/l (ppm) N 0.6 mg/l (ppm) N or 3 % of the measured value
0 to 200 mg/l (ppm) N 2 mg/l (ppm) N or 5 % of the measured value
4) Measurement errors include all the uncertainties of the analyzer. They do not include the uncertainties from the standard solutions used as a
reference.
