Volumetric Test
13. Set the graduated cylinder on a flat surface.
14. Visually measure the fluid in the graduated cylinder from the 40 mL / hr run. Read the level
from the bottom of the fluid meniscus. See Figure 3.
15. Record the volume on the Preventive Maintenance Check Sheet.
If the test procedure fails, review the test set up to ensure that the process has been
followed correctly. Install a new approved IV set and repeat the test.

Gravimetric Test
16. Tare (zero) Scale
17. Weigh (in grams) the fluid in the collection cup from the 40 mL/hr run.
18. On the balance, press Tare (zero) while fluid is in the cup.
19. Remove the cup, empty the cup and dry the inside with a lint-free absorbent cloth.
20. Weigh the empty cup. This value multiplied by negative one (-1) is the weight of the fluid
collected.
21. Record the weight on the Preventive Maintenance Check Sheet.
