delivery volume. This is the inaccuracy volume.

8.Divide the inaccuracy volume by the intended delivery volume and multiply by 100. This is the accuracy error percentage. (See Table 15.)

9.If the accuracy error percentage is greater than ±6%, repeat the test with a new reservoir. If the pump fails a second time, call Deltec’s Customer Service Department.
