Calibration; Setup; Zero Compensation (Aztec 600 Color Only) - ABB Aztec 600 User Manual

Aztec 600 aluminium, ammonia, color, iron, manganese, phosphate
Single- and multi-stream colorimetric analyzers

6.3 Calibration

There is one tab in the Calibration screen for the aluminium, ammonia, iron, manganese and phosphate analyzers.
There are two tabs the Calibration screen for the color analyzer:

6.3.2 Zero Compensation (Aztec 600 Color only)

Fields
Zero Compensation
Frequency
IM/AZT6CR–EN Rev. J
Description
The time the analyzer calibrates.
The next date when a calibration is due.
Frequency at which an automatic calibration is performed.
The concentration of the low standard.
The concentration of the high standard.
The gradient coefficient is an indication of the variation between the actual calibration curve and the
ideal calibration curve.
A limit to the gradient coefficient can be set (ideal coefficient =1).
Above this limit the analyzer fails a calibration.
Default fail criteria occurs when the coefficient exceeds 1 ± 0.6.
If this is set to 'FAIL' (default) after a calibration failure the analyzer stops and displays a failed
calibration message.
If the feature is set to 'ATTENTION' the analyzer continues running after a failed calibration (using the
last valid calibration data). The failed calibration data can be viewed in the 'Audit Log'.
Description
Frequency at which the analyzer performs a zero compensation measurement to account for any
optical variations such as cell fouling when measuring manganese rich waters.
