Preventive Maintenance 7
SIGMA Spectrum Infusion System Pump Operating Software Version 6.02 and 6.05
Preventive Maintenance For Use With MDL Version 6
CAUTION Perform Preventive Maintenance Annually.
Pumps should be tested for proper performance annually and also
whenever damage from drops, fluid intrusion and other causes is
suspected.
CAUTION Avoid Bright Natural Sunlight or Artificial Overhead Light.
Bright Light (equivalent to greater than or equal to 100 watt
incandescent bulb) within 30.5 cm (1 ft) above the Pump’s keyhole
(load point #1) may affect the Pump’s ability to recognize the IV set
slide clamp during set loading. To prevent alarms or continuous
system errors:
Increase the distance between the Pump and the light source.
Move the Pump to an adjacent location.
CAUTION Avoid Overheating.
When operating the Pump, keep out of bright sunlight or direct heat
sources to prevent overheating.
Equipment Required
■ SIGMA Spectrum Infusion System
■ IV set compatible with the Pump being tested (must not include a backcheck valve)
Recommended test set: Preventive Maintenance (PM) Kit P/N 42059, (1 each P/N 99004
Alternate Test Set, 10 each P/N 99051-1 38 cm (15 in) segment.
■ 3-way valve (P/N 55568)
■ IV container (250mL minimum or 1000 mL recommended) to be used as pumping source.
■ Balance or scale with a minimum resolution of 0.1 g calibrated to a range of 0 to 100 g (used
for gravimetric flow rate accuracy test).
■ A 25 mL class “A” graduated collection vessel (used for volumetric flow rate accuracy test).
Volumetric vessel should be TC (to contain) with a resolution of 0.2 mL.
■ Pressure gauge with at least 207 kPa (30 psi) accuracy of 0.5%
■ IV Pole or test fixture
■ One hemostat
■ Saline, Deionized Water (ISO class III) or distilled water
■ Collection vessel (cup, bag, or equivalent)
NOTE: All measurement tools should be calibrated to National Institute of Standards and
Technology (NIST) standards.
NOTE: Do not use tap water.
NOTE: Do not use IV sets that include backcheck valves when performing preventive
maintenance tests.
