Pressure Control Measurement - Argus green stream 707 Service Manual

5.4. Pressure control measurement

5.4.1. Downstream control measurement
Start an infusion at an infusion rate of 250 ml/h according to the user manual.
Insert a pressure gauge on the downstream (patient) side which monitors the pres-
sure in the tube.
Simulate an downstream occlusion.
The pump must stop and the alarm must be activated at the default pressure limit of
700 mbar ±100 mbar, except a different default pressure limit has been configured.
If the result of this control measurement does not fulfil the stated requirement, a
pressure calibration according to chapter "Pressure calibration" has to be done.
5.4.2. Upstream control measurement
Start an infusion at an infusion rate of 250 ml/h with the roller clamp on the up-
stream side near to the pump.
Simulate an upstream occlusion by closing the roller clamp. To avoid the drop
alarm release, simulate falling drops on the drop detector.
The pump must stop after several seconds and an upstream alarm (right hand LED
in the pressure bar graph) must be activated.
If the result of this control measurement does not fulfil the stated requirement, a
pressure calibration according to chapter "Pressure calibration" has to be done.
