Delivery accuracy
• Delivery accuracy for basal rate is ±5%.
Delivery accuracy for bolus volumes < 0.1 unit is ±20% and delivery accuracy
for bolus volumes ≥ 0.1 unit is ±5%.
• All Normal boluses are delivered within 50 minutes ±3 seconds at Standard
rate (75 units, at 1.5 units per minute), and within 5 minutes ±3 seconds at
Quick rate (75 units, at 15 units per minute).
• The maximum infusion pressure generated and the occlusion threshold
pressure is 86.12 kPa (12.49 psi). The bolus volume generated is 0.01225 mL.
