15.7 Performance characteristics
15.7.1 Maximum measured error
5)
0 to 15 mg/l (ppm): 0.5 mg/l (ppm) CaCO
3
Precondition
1)
>15 mg/l (ppm): 2.4 mg/l (ppm) CaCO
3
1) : Calibration within measuring range
With dilution and dilution factor 5:
additionally 2.0 % of end of measuring range
15.7.2 Maximum measured error for sensor inputs
→ Documentation of the connected sensor
15.7.3 Maximum measured 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
15.7.4 Repeatability
5)
± 0.3 mg/l (ppm)
With dilution and dilution factor 5:
Additionally 1.5 % of end of measuring range
15.7.5 Repeatability of sensor inputs
→ Documentation of the connected sensor
15.7.6 Measuring interval
Continuous (approx. 7 min), adjustable 10 min to 24 h
15.7.7 Sample requirement
Without dilution module
14.7 ml (0.50 fl oz)/measurement
With dilution module
• Sample: 11 to 15 ml (0.37 to 0.51 fl oz)/measurement (depends on dilution factor)
• Dilution water: 17 to 21 ml (0.57 to 0.71)/measurement (depends on dilution factor)
5) According to ISO 15839 with standard solutions. Measured errors include all the uncertainties of the analyzer.
They do not include the uncertainties from the standard solutions used as a reference.
