6. Setting System Parameters and Systems Calibration
6-80
2.4
4 ± 3ºC Calibrate
:
2.4.1 Add 4 ± 3ºC water to the 3.0 L Reservoir
2.4.2 Press NEXT to pump water at 500 ml/min into the disposable. If
the procedure has to be abandoned press EXIT and the system
will return to the Calibration/Set-Up screen.
2.4.3 Keep water in the 3.0 L Reservoir at 4 ± 3ºC.
2.4.4 After a minimum of two minutes a numerical keypad will appear.
Wait until the thermometer reading stabilizes then enter the actual
temperature reading, minus 1ºC offset, from the thermometer,
which must be between 1ºC and 7ºC. If not, add more 4 ± 3ºC
water to the 3.0 L Reservoir.
2.4.5 Press UPDATE to save the value. If the temperature was still
fluctuating when UPDATE was pressed, the system will not
update and continue to wait until the temperature stabilizes.
2.5
20 ± 3ºC Calibrate
:
2.5.1 Add 20 ± 3ºC water to the 3.0 L Reservoir. Continue pumping until
the thermometer reading stabilizes before entering the actual
temperature.
2.6
40 ± 3ºC Calibrate
:
2.6.1 Add 40 ± 3ºC water to the 3.0 L Reservoir. Repeat.
2.7
After the last temperature water, 40 ± 3ºC is updated, the system will
return to the Calibration/Set-Up screen.
Verification:
2.8
Press HARDWARE. Enter password 013192.
2.9
Add more 40 ± 3ºC water to the 3.0 L Reservoir.
2.10
Press the RIGHT VALVE key to set the valve to the infuse position.
2.11
Press the PUMP SPEED three times to set the flow rate to 500 ml/min
2.12 Wait at least 2 minutes for the temperature to stabilize. The INPUT and
OUTPUT TEMPERATURE probe readings should be similar and stable
(the values not in the parentheses).
2.13
Compare the displayed numbers on screen to the thermometer reading.
The accepted tolerance is 1ºC for fluid temperature between 30ºC to
40ºC.
2.14
Verify the 20 ± 3ºC and 4 ± 3ºC water. The accepted tolerance is 2ºC.
2.15
Press PUMP SPEED to set the pump speed back to 0 ml/min.
2.16
Press CANCEL to return to the Calibration/Set-Up screen. The system is
temperature calibrated and verified.
2.17
After a temperature calibration has been completed, a power calibration
should be performed. See Power Module and Pump Calibration in this
chapter.
