10.2 Sensor Simulator: P/N: 186-0137

Instructions for Use
Insert 2CH/4CH BIS Sensor Simulator service tool into patient interface cable. Impedance
test will be initiated by BIS Monitoring System when it detects that simulator has been
inserted.
Description of tool:
The 2CH/4CH BIS Sensor Simulator is a service tool that allows for the verification of
proper impedance values being detected by the BIS Monitoring System during the "Sensor
check". This test is part of the initial test that each monitor performs. The simulator also
allows for safety testing of BIS monitors in the field by allowing connection of the test
equipment to the monitor via the patient interface cable (PIC).

Figure 8 - Schematic of the BIS Sensor Simulator

Schematic of the 2CH/4CH BIS Sensor Simulator circuitry. IO3 – IO6 connect to 4 input
signal pins on a 2 channel patient interface cable. ( IO1 – IO6 connect to 6 input signal pins
on a 4 channel patient interface cable.) The Inputs (+ and -) are where one connects the test
signals to test the BIS Monitor.
Test types allowed:
Sensor check
This checks and verifies that the monitor is reporting the proper impedances that it sees
from the BIS Sensor Simulator. This procedure verifies the proper functionality of the BIS
monitoring system. Connect the BIS Sensor Simulator to the BIS Monitor at the patient
interface cable. See Section 6.3.3 "PIC Checkout Procedure" for instructions.
The monitor should proceed to recognize that a sensor was connected and report the proper
impedance values as shown below:
