PROCESS CALIBRATION
A Process Calibration (PROCESS CAL) can be performed only if the analyzer has successfully passed a
2-Pt calibration. During PROCESS CAL, none of the solenoid valves are energized and the instrument is
calibrated directly to the sample running through the flowcell. The analyzer calibrates by changing the
offset of the strength/slope taken during the last 2-Pt calibration.
To perform Process Calibration:
From the Commands Window, press the “PROCESS CAL” button. Press on the “0.0 ppb” to open the
numerical keypad.
Enter in the expected concentration of the sample and press “ENT.” You will then see the
entered value in the “Process cal. value” window. If you wish to make changes to the entered
value, press the number “XX.X ppb” to edit the value and hit “ENT” again. Press
“CALIBRATE” when ready. The Process Calibration will begin.
