Measure by using a tachometer:
i.
Close the door. Set the pump speed to 10 ml/min. Use a tachometer to
measure the rotational speed of the pump head. The accepted tolerance is 1.95
rpm ± 25%.
ii.
Press PUMP SPEED again to change the pump speed to 100 ml/min. The
accepted tolerance is 19.65 rpm ± 10%.
iii.
Press once more to change speed to 500 ml/min and repeat the measurement.
The accepted tolerance is 97 rpm ± 10%.
iv.
Press once more to change speed to 750 ml/min and repeat the measurement.
The accepted tolerance is 146 rpm ± 10%.
v.
For 1000 ml/min option, press once more to change speed to 1000 ml/min and
repeat the measurement. The accepted tolerance is 195 rpm ± 10%.
e.
Input and Output Temperature Probes and “Over Temperature” Alarm
Prepare at least 2 liters of 37º - 43ºC fluid
i.
Connect the fluid supply to the disposable. Remove the patient line from the luer
connector. Insert the thermocouple approximately 2” into the connector
previously connected to the patient line.
ii.
Press the RIGHT VALVE key to set the valve to the infuse position. Open the
fluid supply and set the pump speed to 500 ml/min.
iii.
Let the temperature stabilize, wait at least 2 minutes. The INPUT
TEMPERATURE and OUTPUT TEMPERATURE value readings (the values not
between the parentheses) should be within (2ºC).
iv.
Compare the numbers displayed, on screen, to the thermocouple reading. The
accepted tolerance is 1ºC for fluid temperature between 30ºC to 40ºC and 2ºC
outside this range.
v.
Press PUMP SPEED to set the pump speed back to 0 ml/min.
vi.
Press CANCEL to return to the Calibration/Set-Up screen.
vii.
Press EXIT SERVICE to return to PRIME screen.
viii.
Prime the unit and the patient line with room temperature water.
Prepare at least 2 liters of 43º- 45ºC fluid.
ix.
Connect this fluid supply to the disposable. Infuse at 500 ml/min.
x.
Compare the numbers displayed, on screen, to the thermocouple reading. The
alarm sounds when the screen reads between 42º
– 42.5ºC.
xi.
Record the temperature when the “Over Temperature” alarm occurs. The
accepted tolerance of the temperature between the thermocouple and on the
screen should be within 1º
to 2ºC of each other.
