DSC Checkout Procedure
Periodically the DSC and associated cables and connectors should be inspected for
physical damage.
1. Inspect the DSC case to ensure the plastic is not cracked or broken.
2. Inspect the gasket seal around the perimeter of the DSC to verify the physical
integrity of the seal.
3. Inspect the cables and strain relief mechanism.
4. Inspect the connector that plugs into the monitor for damage or poor strain relief.
5. Inspect Patient Interface Cables (PIC) for damage to cable or connectors.
6.
Perform DSC Self Test. See section 6.2.3.1.
5.2.5
Patient Interface Cable (PIC) Checkout Procedure
The sensor check can be done using a Sensor Simulator (P/N 186-0105), following the
instructions in Appendix 9.2. If a simulator is not available, use the following procedure to
make a test sensor:
1. Remove a new sensor from its plastic carrier sheet and place on flat surface with the
adhesive facing up.
Note:
Be careful that gel does not leak onto hands or connector during this
procedure.
2. Place the end of a small paper clip at the midpoint of electrode element 1 then lay it
across element 2. (Elements 1 and 2 are the two closest together.)
3. Fold electrode element 3 over onto electrode 2, pressing adhesive surfaces together
and making sure the paper clip remains in place.
4. Fold electrode 1 over on itself, securing the other end of the paper clip and pressing
adhesive surfaces together. If necessary, secure it in place by wrapping a piece of
tape around the outside.
5. Connect this test sensor to the sensor PIC. All impedance tests should complete
successfully, with low impedance values. Typical values using this alternative test
sensor are less than 5 Kohms.
