Cell Failure Checks
Cell failure is covered in detail in Part I: Control Units, section
4.4.1.3, Cell Failure. Cell replacement is covered Part II: Analysis Units
chapter 5, Maintenance.
When the sensor in the 3010P begins to fail, the analyzer will usually
require more and more frequent calibration. If recalibration raises the
readings temporarily only, suspect the cell.
You can check the output of the cell itself by scrolling the MAIN
MENU TO
SENSOR.
When you ENTER the function, the sensor report screen appears.
