5.4. Checking disengagement system
1.Start the device.
2.Place a 50/60 ml syringe in the INJECTOMAT
3.Activate the disengaging lever.
q
Ensure an acoustic and visual alarm is present.
4.Maintain the disengagement lever in high position and move the driving block
q Check easy driving block displacement (manual displacement).
5.Release the lever
q Ensure there is no alarm.
q Check driving block locking.
5.5. Checking force sensor
1. Proceed to test 9 (see section 3.3: checking the INJECTOMAT)
2. Use the disengagement system to pull the pusher backward so no force is applied to the sensor.
q Displayed value should be between 0 and 100 g
3. Press and release the force sensor
q Displayed value should be between 0 and 100 g
4. Apply a known force (about 5 Kg) on the pusher.
q Displayed value should be 5 Kg +/- 250g.
5.6. Checking back-pressure
NOTE: The Injectomat 2000 Anästhesie initiates the sensor after pusher engagement. When testing
back-pressure, the infusion should be started with no pressure on the line.
1. Start the device by pressing the ON key.
2. Place a manometer (or any other pressure measuring instrument) at the syringe outlet.
3. Select Braun Perfusor 50 ml Syringe.
4. Select the Medium Limit Pressure by pressing the LIMIT PRESSURE key.
q M = (medium limit pressure) = 500 mmHg +/- 75 or 0.65 bar ± 0.1 bar.
1. Select maximum flow rate
2. Start the infusion (press START/CONFIRM).
q Ensure there is no acoustic and visual alarm (back-pressure Led off),
q
Check infusion indicators are flashing.
q Check visual and acoustic alarm for a 500 mmHg +/- 75 or 0.65 bar ± 0.1 bar pressure.
NOTE: If the pressure value measured according to the selection made falls outside the reference val-
ues, refer to the "
EtA9 EtA9
" calibration test (see Chap.3.2.3.).
NOTE: Before calibrating the force sensor, check the voltage between point J09.1 (earth) and J09.4
using an oscilloscope. Voltage value = 0.6 V + 0.05 V (square pulse).
