This section outlines the procedures for calibration of the Alaris® GW Volumetric Pump.
All of these calibrations should only be carried out by qualified biomedical engineers. If in any doubt about how to perform the tests,
in particular the pressure sensor calibration checks, contact your local Cardinal Health Service Centre who will be able to assist.
Calibration procedures
Recommended Calibration Equipment
Specialised test equipment is not required for the majority of the functional tests to be carried out on the pump. In order to calibrate
or verify the occlusion alarm point or volumetric accuracy, the following equipment will be necessary:
IV infusion set, suitable for the Alaris® GW Volumetric Pump with standard LUER lock taps for connecting to other test equipment.
If the standard sets are not available, it is possible to order a basic "test set" that is available from your local ALARIS® Service Centre
- part number 0000TG00074. Note that all sets should only be used for a single calibration operation.
Pressure gauge for measuring liquid pressure, with a full scale of 0-2 bar (0-1500mmHg) ±20mmHg.
either:
Class A 50ml glass burette with graduations down to 0.1ml and calibrated down to ± 0.05ml.
or:
Calibrated scales accurate to at least ± 0.01g.

Displaying the Volumetric and Pressure Calibration Values (CODE )
Use of this access code simply displays the calibration values stored in the software.

Enter the access code 2.
2.
Press

3.
Switch the pump "OFF" if there are no further tests to be done at that time.
Battery Calibration (CODE 4)
The pump must be connected to the AC power source throughout the duration of the test. The test can be aborted at any time by
switching the pump off using the
pump. This calibration should only be performed on a fully charged battery. Ensure the pump is plugged into the mains for at least
4 hours before starting this procedure.
1.
Plug a mains lead into the pump.
2.
Prepare a fluid-filled looped tubing, load it into the pump and close the door.
Enter the access code 4.
3.
4.
The test will start automatically. The pump infuses at 999 ml/h internally switching to the battery power source to discharge the
battery; the air-in-line alarm is disabled. Throughout this test the time indicator will increase in minute intervals.
5.
As soon as the pump detects that the battery is discharged, the time shown on the main display will stop increasing and begin to
flash.
6.
If the time is greater than two hours and the low point voltage value is within the allowable range of 6.5 to 7.8 volts, then the
display shows "PASS" / "xx:xx" / "bx.x", the pass indication, elapsed time and battery low point value in volts. Otherwise the
display shows "FAIL" / "xx:xx" / "bx.x".
