Performance
Downstream occlusion time to alarm for occlusion pressures adjusted to LOW (6 psi), MEDIUM (13
psi), and HIGH (19 psi)

:
All safety related sensing systems are automatically checked for proper operation periodically during
setup and pump running conditions. Faults are identified by SYSTEM ERROR codes.
See the Specifications section of the Operator’s Manual for additional specifications.
Effect of Fluid Container Height
2
The performance of the infusion pump will be influenced by the forces of gravity on the fluid being
administered to the patient. When a fluid container is positioned above or below the patient’s admin-
istration site, pressure forces associated with the fluid’s head-height (distance measured from the cen-
ter of the pumping mechanism to the top of the fluid in the source container) will cause deviations in
the nominal specification for device flow rate accuracy. The nominal head-height used for the flow
rate and the graphical presentation is 24” (61 cm). For example, the deviation from the nominal
flow rate accuracy from +24” to -20” (-51 cm) head-height has an influence of a possible -4% in
flow rate accuracy when the flow rate is set to 25 mL/hr.
Bolus Accuracy
The SIGMA Spectrum IV pump may have an optional bolus mode of operation. This feature allows
the user to perform a BOLUS SETUP action. To use this feature the pump must be programmed with
either a specific rate or a specific amount to be delivered in a certain amount of time.
