Routine Maintenance
Dry Set Pressure Verification (Test 12)
When servicing the pump perform the following pressure calibration verification procedure.
Note: If the pump fails this test, perform the 'Dry Set Pressure Calibration' procedure. See Chapter 2. for instructions.
Procedure:
1. Connect the pump to the AC mains and set up the equipment as shown below..
Note: Set the pressure unit selector switch (on the back panel of the pump) to mmHg .
2. Enter self-test mode, press the

MMHG
.
Allow the pump to warm up for approximately 30 minutes before continuing with this test.
3. Load an IV infusion set and close the door.
4. Apply a pressure of
000
mmHg and verify that the pump displays a reading of
