8.7.1 Method of Operation
The CA6 analyzer measures the LED intensity to attain the Reference and Sensor values. The absorbance
value is calculated by comparing the Sensor value (Reading) and the Reference value.
As the Colorimetric cell becomes fouled, the LED supply voltage yields a lower and lower Reference
value. When the Reference value drops to the Minimum Reference value a Fault Alarm is initiated but
the analyzer continues to make measurements. When the reference value falls 25% below the Minimum
Reference value that is set in the service screen, the Analyzer goes into a Failure Alarm and stops
working.
Clean the Colorimetric cell. Press RUN and START ON-LINE to restart the analyzer.
