Service Tool Procedure, Version 2
This procedure applies only for Service Tool M1012-61601 in combination with C.O. modules with
option C10.
1 In monitoring mode, connect the C.O. interface cable to the module.
2 Connect one side of the service tool to the injectate receptacle of the C.O. interface cable and the
other side to the catheter cable receptacle.
3 Enter Setup C.O. menu and check results for:
– Method of measurement
– Catheter constant
– Tblood
4 Enter C.O. Procedure window and check results. The expected results are
– Tran sp u l m o na r y 341
– Tblood = 37.0

BIS Performance Test
These tests check the performance of the BIS measurement.
PIC/DSC Test
1 In monitoring mode connect the sensor simulator (for maximum usage please refer to the
documentation delivered with the sensor simulator) to the patient interface cable.
2 Enter the BIS menu and select Open Window.
3 Start impedance check by pressing StartCyclicCheck. Check the displayed results. Expected
results are:
– Electrode 1 (+): 4-6 k
Ω
– Electrode 2 (Ref ): 8-12 kΩ
– Electrode 3 (1-): 1-3 kΩ
– Electrode 4 (2-): 1-3 kΩ
Nurse Call Relay Performance Test
The nurse call relay performance test can be performed either at the phone jack type connector (this
only tests one relay) or at the multi-port nurse call connector (to test all three relays).
Phone Jack Type Connector Test
This test checks the operation of the Nurse Call Relay. The Nurse Call Relay test is recommended for
customer sites where the nurse call is in use. The Nurse Call relay functions as follows:
• Standard Operation—Relay open.
• Alarm Condition—Relay closed.
Tools required: Ohmmeter.
1 Plug a phono connector into the Nurse Call Relay connector.
2 Connect the ohmmeter.
3 If no alarm occurs, the relay contacts are open. When an alarm occurs, the relay contacts close.
