Preventive Maintenance Tests
Tests Performed Pass Fail
1. Keypad Test
Perform the keypad test for proper key operation.
Pass criteria:
All keys work as intended
2. Memory Test
Pass criteria:
Rate and VTBI parameters were saved.
(Rate = 100 mL/hr VTBI = 50 mL)
3. Downstream (Distal) Occlusion Sensor Test
Test Results: ___________ (check one: ___ kPa ___psi)
Pass criteria:
All steps completed successfully.
Pump displays a DOWNSTREAM OCCLUSION alarm at a pressure within
the 89 kPa ±41 kPa (13 psi ±6) psi occlusion trip pressure setting.
Pump automatically restarts when occlusion is removed.
(Rate =100 mL VTBI = 50 mL) (48 kPa to 131 kPa) (7 psi to 19 psi)
4. Upstream (Proximal) Occlusion Sensor Test
Pass criteria:
All steps completed successfully.
Pump goes into UPSTREAM OCCLUSION alarm prior to the “infusion
complete” message.
(Rate = 100 mL/hr VTBI = 13.3 mL) (approximately 8 min)
5. Flow Rate Accuracy Test

(Rate = 40 mL/hr, VTBI = 20 mL) (Time = 30 min)
Gravimetric
Gravimetric: ____________ g
Pass criteria:
Collected fluid of 20.0 g ±5% (19.0 - 21.0 g)
(Rate = 40 mL/hr, VTBI = 20 mL) (Time = 30 min)
