Sensor Check
The Sensor Check tests the impedance of each electrode on the BIS sensor to verify that it is
within an acceptable range for monitoring. A Sensor Check is initiated automatically when
the sensor and PIC are connected to the BISx. It may also be initiated by the user by
pressing the
[SENSOR CHECK]
soft key.
The message, “Sensor Check in Progress” appears. When the sensor successfully passes the
test, the Main Screen displays and monitoring begins.
If the sensor does not immediately pass the test, or if the user has manually initiated the test,
the Sensor Check Graphic Screen displays. This screen shows a sensor with a symbol inside
each electrode. The symbol indicates the status of that electrode:
•
A circle with a question mark indicates that no status is available (Lead is off).
•
A green circle with a checkmark indicates that the electrode impedance is within the
acceptable range. If all electrodes contain a checkmark, monitoring can begin.
•
A red circle with an ‘X’ indicates that the electrode impedance is not within the
acceptable range.

The monitor continues updating the values until all impedance values are acceptable. To end
the impedance test, press
[EXIT]
. The Sensor Check impedance test must be successfully
completed before normal processing resumes.
The “Show Values” Sensor Check Display:
Additional detail may be viewed on this screen by pressing the
[SHOW VALUES]
soft key.
In this display, the impedance value for each electrode, in kilo ohms, appears on the screen
along with its status:
