Pressure sensor calibration
1
Go to the program mode (without IV-administration set).
2
Enter in address 399 the value 1234.
3
Press the key "START/STOP"
The display shows e.g. [Set] [-2- ]. Choose the IV set (no. 1 to 4) by pressing the key [1].
4
Press the key "START/STOP" (The pump mechanic runs with a rate of ca. 200 ml/h).
The display shows [CAL.] [door]. By pressing the key "1" it is possible to show the stored value in mV
in the display.
5
Press the key "START/STOP". The offset voltage, without IV-set, will be stored.
The stored value will be acknowledged by a sound.
6
Press the key "MODE".
The display shows [CAL.] [0bAr]. By pressing the key "1" it is possible to show the stored value in mV
in the display.
7
Install an used (milled) IV-administration set (Open the roller clamp).
8
Start the pressure build-up by occluding the tube on the patient side to control the mechanical pressure
limit.
Minimum 1.2 bar has to be reached for a successful calibration.
9
Gradually decrease the pressure by removing the occlusion.
10 Wait ca. 30 sec., then activate the key "START/STOP". The reference value for sensitivity calculation will
be stored. The stored value will be acknowledged by a sound.
11 Press the key "MODE".
The display shows [CAL.] [1bAr]. By pressing the key "1" it is possible to show the stored value in mV
in the display.
12 Start the pressure build-up again, wait until the manometer shows 1 bar, then activate the
key "START/STOP". The absolute value at 1 bar will be stored. The stored value will be acknowledged
by a sound.
13 Gradually decrease the pressure.
14 Turn the pump off- and on again.
15 Select the rate at 500 ml/h.
16 Press the key "START/STOP".
17 Start the pressure build-up to control the electronic pressure limit.
18 The alarm must be activated at ca. 700 mbar
±
100 mbar if the default value = "7".
If the result is not satisfactory repeat the sensor calibration.
19 Switch the pump off.
