Operation
Sensoface
®
menu
In the Sensoface
®
menu you see the criteria that
control Sensoface
®
display. Each criterion is dis-
played separately with the corresponding evalua-
tion. This gives you important information on the
condition of you electrode. Sensoface
®
alerts you
in time for possible errors or aging of your elec-
trode.
The worsening of a Sensoface
®
criterion leads to
the devaluation of the Sensoface
®
display. This
devaluation is permanent. An improvement can
only take place after a calibration.
Here, the Sensoface
®
display provides information
on zero and slope of the electrode. For the exact
zero and slope values, refer to the Electrode Data
menu.
Zero and slope of the electrode are okay.
Zero and slope of the electrode are still okay. How-
ever, the electrode should be replaced soon.
Zero and/or slope of the electrode have reached
values which no longer ensure proper calibration. It
is advisable to replace the electrode.
The values for zero and slope are determined dur-
ing calibration only. Therefore, correct information
depends on a proper calibration. Make sure that
you always use correct and pure buffer solutions.
