10.1 Sensoface
The Sensoface feature is active whenever Sensocheck is active. This
feature monitors the sensor for defects in the sensor or cable, and
indicates the maintenance status of the sensor (
Table 22 ).
10.2 Sensocheck
Important Note: Sensocheck must be switched off for Type B sensors.
The Sensocheck feature monitors the sensor electrodes and wires for
open circuits. When problems are detected, the error message “Err 33”
is displayed, along with an icon corresponding to the type of problem.
Table 23 shows the sensor types that Sensocheck monitors.
Sensocheck can be switched off in the configuration menu.
Note: For confirmation a Sensoface is displayed after calibration.
