Testing Pressure Output
Note the following test guidelines:
Guidelines Requirements
Maintenance Interval Once every three months is suggested.
Equipment • Digital Multimeter (DMM), 1 mV (resolution)
• PMIO cable (part # 025420)
• DC bench power supply (10 V DC)
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 rear of the monitor, connect a PMIO cable to the PMIO connector, but not to an external patient
bedside monitor.
3. Using the DC bench power supply and the Digital Multimeter (DMM), do the following:
A. Set DC power supply to 10 ± 0.1 volts and connect “ + ” and “ - ” leads to pins “ 1 ” and“ 4 ” of the six pin
cannon connector, respectively.
B. Connect the “ + ” and “ - ” leads of the DMM to pins “ 2 ” and “ 3 ” of the six pin cannon connector,
respectively.
4. Turn on the monitor. On the touch screen, press Synchronize to Monitor to test the following ICP
values.
Simulated Pressure (mmHg) Simulated Voltage (mVDC)
0 0.000 ± .25
25 1.250 ± .25
50 2.500 ± .25
100 5.000 ± .25
Note that pressing Check Additional Values each time will advance to the next fixed ICP value:
5. Turn off all test equipment, power down monitor, and then disconnect all test equipment.
