6.3. Pressure calibration
6.3.1. General
The volumetric infusion pump ARGUS 707 V contains two pressure sensors:
- One upstream sensor, bottle side (left input)
- One downstream sensor, patient side (right output).
A pressure calibration becomes necessary if:
- the pressure control measurement is not
accurate enough
- a pressure sensor is replaced
- the main board is replaced or a new set is configured
Needed equipment:
- a manometer with a resolution of 0.1 bar
- a 3-way stop cock and a clamping shears
- the chosen IV set (refer to the list including the
recommended IV set in the user manual)
CAUTION!
The pressure calibration procedure always includes all of the follow-
ing steps, including a control measurement.
Key functions during pressure calibration:
By the "MODE" key you can switch to the next calibration step.
By the "START/STOP" key you can store the value of the involved pressure
sensor, this will be acknowledged by a sound (beep).
By pressing the "1" key you can switch off and on the actual value of the
pressure sensor in the display. The value is displayed in mV.
By pressing the "10" key you can switch off and on the motor.
Don't use it by the standard calibration.
By pressing the "100" key, the pump rate can be changed from 100 to 200
ml/h and back (toggle action).
It is recommended to reduce the rate when the pressure is near 1.2 (1.0) bar,
this allows a more precise calibration.
