Error Codes and Device Messages
Error messages are indicated as "ERROR ..." on the display. Information on the sensor
condition is indicated by the "Sensoface" icon (friendly, neutral, sad) possibly accom-
panied by an info message ("INFO ...").
Example of an error message:
ERROR 8 (identical calibration media)
Sensoface (the "smiley" icon) provides
information on the sensor condition (main-
tenance request). Measurement can still be
performed. After a calibration, the corre-
sponding Sensoface icon (friendly, neutral,
sad) is shown together with the calibration
data. Otherwise, Sensoface is only visible in
measuring mode.
The most important error messages and
"Sensoface" info messages are shown on the
inside of the protective cover.
A complete list of messages and their mean-
ings is provided in the following tables.
Example of a "Sensoface" message:
