Table 2 Electrode icons
Icon Description
Sunny icon:
The calibration has been performed on the electrode present in the system. Everything
is just right!
Cloudy icon:
The electrode calibration of the electrode present in the system should be performed
within 12 or 24 hours.
Stormy icon:
The calibration date has elapsed for the electrode present in the system.
If acceptance limits have been set for the calibration: at least one calibration result lies
outside the programmed acceptance limits.
Question mark:
There is a problem in the editing of the electrode system. You need to be in Supervisor
mode to solve the problem. Check the sequence/method parameters of the reagent or
the electrode.
Check the sequence or method, (press 1 in the Main window). The instrument indicates
the possible errors and prompts you to correct them until ? disappears.
