IF ANY FAILURES ARE NOTED:
•
Swap BISx with known good one to verify that problem does not exist with the
monitor.
•
If failure is isolated to this BISx, it will need to be serviced. See section 8.12 “What
To Do With a Component That Requires Service.”
8. Press [HOME] to exit. If PIC and Sensor are available, perform PIC Checkout
Procedure. See section 6.3.3 “Patient Interface Cable (PIC) Checkout Procedure.”
6.3.3 Patient Interface Cable (PIC) Checkout Procedure
The successful completion of this test will verify function of the BIS VIEW system from the
BISx circuits to the patient connector. Since the conductors used are located both in the
BISx and the PIC, use a swapping technique to isolate the faulty component.
Use a Sensor Simulator (P/N 186-0137) or make a Test Sensor for this test. (See Section
10.3 “Test Sensor” for details.)
IF ANY FAILURES ARE NOTED, SEE SECTION 7.3,
“BIS VIEW System Messages And Corrective Actions”.
1. Using a known good BIS VIEW monitor (see section 6.3.1 “Monitor Checkout
Procedure) and a known good BISx (see section 6.3.2 “BISx Checkout Procedure)
connect the PIC that you are testing to the BISx, and connect the BISx to the BIS
VIEW monitor.
2. Press the monitor’s ON/Standby button to start up the monitor and BISx. At the
completion of the power up self-test, verify that the screen message “Connect sensor
or cable” displays.
3. Connect a Sensor Simulator (see Section 10.2) or Test Sensor (see Section 10.3) to
the PIC cable.
4. A sensor check is initiated when the sensor and PIC are connected to the BISx. (It
may also be initiated by pressing the
[SENSOR CHECK] soft key. Note that if a
BIS Extend Sensor is in use, you must press [CONTINUE] to initiate the check.)
The message, “Sensor Check in Progress” appears. When the sensor successfully
passes the test, the BIS Trend screen displays.
5. If the Sensor Check is not immediately successful , the Sensor Check Graphic
Screen displays automatically. This screen shows a sensor with each electrode
numbered. Colors indicate the status of each electrode.
•
White hollow circle – No status is available (Lead is off).
•
Green circle – The electrode impedance is within the acceptable range.
•
Red blinking circle – The electrode impedance is not within the acceptable range.
The impedance value for each electrode, in kilo ohms, appears on the screen along
with its status:
