Note the following test guidelines:
Guidelines
Requirements
Maintenance Interval
Once every three months is suggested.
Equipment
•
Digital Multimeter (DMM), 1 mV (resolution)
•
Natus Camino Fiber Optic Catheter Cable
•
Natus Camino Fiber Optic Catheter (part # 110-
4BT, ICP/temperature measurements)
•
PMIO cable
•
Resistors (10k
Ω
x2)
•
Potentiometer (10K
Ω
x1, 10 turn)
Notice
Before performing this test, verify that the Camino ICP Monitor is turned off and not connected to any cables.
1.
Plug the Camino ICP Monitor to an AC wall outlet.
2.
On the right side of the monitor, connect a Fiber Optic Catheter Cable to the
ICP
and
Temperature
connectors.
3.
Using a functional Fiber Optic Catheter, firmly connect the pressure transducer connector to the Fiber Optic
Catheter Cable.
4.
Connect the leads of the Digital Multimeter (DMM) to pins
1
(1 Volt) and
3
(GND) of the Fiber Optic Catheter
Cable temperature connector.
5.
Turn on the monitor. Verify the DMM reads 1.0000 ± 0.002 VDC.
6.
Turn off the monitor and remove the DMM leads from the
Temperature
connector.
7.
Connect two 10K
Ω
resistors and a 10K
Ω
potentiometer to the temperature transducer connector.
Connect the leads of the DMM to pins 2 (Vin) and 3 (GND).
