3.
Verify that no more than 0.5 mL of fluid is allowed to flow in the first 60
seconds, and that no gravity flow occurs after 60 seconds. Measure the
fluid gravimetrically with a scale by collecting the fluid with a pipettor
(recommended size 1000
μ
L) or by counting drops in the administration
set drip chamber:
Q
For a drip chamber with 10 drops/mL,
≤
0.5 mL
≤
5 drops
Q
For a drip chamber with 60 drops/mL,
≤
0.5 mL
≤
30 drops
4.
Repeat this procedure for the other pump.
Electrical Safety Tests
Ground Impedance
1.
Using an equivalent NFPA-99 tester, measure the resistance between one
of more accessible dead metal parts such as the communication port or
the mounting nut of the PANEL LOCK switch and the ground pin of the
attachment plug.
2.
Flex the cord at the strain relief at each end of the cord during the test.
The resistance must not exceed 0.5
Ω
..
Current Leakage
1.
Measure the current leakage at the communication port of the mounting
nut of the PANEL LOCK switch. Perform all four leakage current test
modes per UL 544 (Normal Polarity/Normal Ground, Normal Polarity/
Open Ground, Reverse Polarity/Normal Ground, Reverse Polarity/Open
Ground).
2.
Record the highest reading. The leakage current must not exceed 50
μ
A
in any mode.
Accuracy Tests
Any one of the tests described in this section can be used to test the accuracy
of the pump. You can perform just the One-Hour Accuracy Test (“One-Hour
Accuracy Test” on page 10-14), or one of the shorter tests (“Measurement by
volume per time” on page 10-13 or “Measurement incorporating VTBI
option” on page 10-13). The One-Hour Accuracy Test should be performed if
either of the shorter tests fail.
