14 | Covidien
•
No drip sensor attitude independence
•
Transmitter and receiver on either side of tube track
•
Ultrasonic signal requires a medium
•
Without fluid: little or no signal received
•
Fluid provides a medium to receive a stronger signal

17 | Covidien
•
Perform at room temperature (22 ± 2 ºC) with AC power
•
Use a new Feed-Only set filled to 500mL mark with water
•
Hang set with top of water column 15.2cm above pump •
Run in continuous mode at 125 mL/hr for 15 mins.
•
Collect water in calibrated cylinder for 30 mins.
•
Accuracy is ±7%. Water further overdelivers by 4%.
•
Amount collected should be: 60.63 – 69.38 mL
