Is there a simulator available for checkout purposes?
XP SYSTEM
SENSOR SIMULATOR: P/N: 186-0137 INSTRUCTIONS FOR USE:
Description of device
The 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.
NOTE: The life expectancy of the Sensor Simulator is 25 connect / disconnect cycles.
S1 - S4 connect to 4 input signal pins on the 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 Sensor Simulator. This procedure verifies the proper functionality of the BIS monitoring system.
Connect the Sensor Plus simulator to the BIS Monitor at the patient interface cable.
The monitor should recognize that a sensor has been connected and report the proper impedance values:
|
Electrode # |
1 |
2 |
3 |
4 |
|
Acceptance Range in Kohms |
4 - 6 |
8 - 17 |
3 - 5 |
2 - 4 |
The monitor then proceeds to display the BIS screen. BIS is blank and after a few seconds
SQI = 100.
Safety Testing: Leakage Current.
Leakage Current testing should be performed by a qualified Biomedical Engineering Technician or authorized personnel only.
- Connect Sensor Simulator to the patient interface cable of the BIS monitor as if it was a sensor connection.
- Short the two circular terminals at the end of the simulator using conventional methods such as jumpers or alligator clips. Wire attached with screws will work also.
- Connect the test signal to the shorted terminals. Make sure that you are not touching the simulator beyond this point.
Proceed to test instrument for Leakage current as per established facility protocols and procedure for safety testing of medical devices.
