Volumetric Accuracy Testing
Description
A predetermined amount of water is delivered into a collection device
such as a burette or graduated cylinder. The amount of water delivered is
compared to the amount that the pump is programmed to deliver.
Nominal system accuracy is given in the technical specifications section
for the pump. That is, under the test conditions described below, the ac-
curacy of the pump and Medication Cassette Reservoir will be nominal
with a 90% confidence level. The nominal test conditions are as follows:
degassed water at 25 ± 5°C without back pressure.
