9.2.4 Fluid Deficit Measurement Test
The test setup is depicted in Fig. Fluid deficit measurement test [} 50]. It is critical
that the collection container be placed on the scale as shown in Fig. Fluid deficit
measurement test [} 50].
1.
If the basic function tests described in the Chapters Scale Test [} 44], Flow Rate
Test [} 43] and Pressure Measuring Test [} 49] have been conducted, skip to
step 2. If not, conduct the Basic Function Tests described in Chapter Flow Rate
Test [} 43] steps 1 to 11.
2.
"Zero" the fluid deficit display by pressing the Zero button (see Fig. Front of ir-
rigation pump unit [} 25], item (9)).
3.
Press the Pause/Resume button.
4.
Let the system run for 1 minute. The container should have ~800 ml of fluid
but the fluid deficit display should stay at ~0 ml.
The acceptable tolerance is ± 100 ml for AQL-100 respectively ± 60 ml for
AQL-100S.
Record results in the test log in the Appendix [} 62]. The test is successful if res-
ults are within acceptable tolerance limits.
