This test is used to confirm that the pumping accuracy of the system as a whole, including the tubing, is within the specified limits.
In the most controlled conditions, a needle should be used to pump liquid into the weighing beaker to prevent liquid touching the
sides of the beaker and to provide some back-pressure so that leaks/overflows do not affect the readings. As a result of these and
other errors, if the system fails just marginally, it is worth performing the test a second time. If it still fails, return the pump to your local
ALARIS® Service Centre for further analysis. The head height on IV infusion set should be approximately 30cm.
