5. Select the following values: Nominal pressure: 150 mmHg
6. Press the START/STOP key. The START operating mode LED (Fig. Front of the
device [
}
22]
(3)
) lights up. The roller wheel starts to turn.
7. Fill tube set completely with fluid. Wait until the instrument recognition has
finished.
8. Close the clamp (Fig. Tube set elements [
}
26]
(3)
).
Performing the basic function test 1. Empty measuring beaker.
2. Open clamp (Fig. Tube set elements [ } 26]
(3)
) and stop after 30 seconds.
3. Press the START/STOP key once this time has passed. The graduated measuring
beaker must contain approx. 0.75 l (±10 %) of fluid.
The basic function test has been successfully completed once these values have
been reached.
10.3 Pressure Measuring Test
The pressure test checks the pressure chamber, the pressure sensors, and the pres-
sure measuring to ensure all elements are functioning properly.
Preparing the pressure measuring test 1. Insert a test tube set into the device (without connected instrument).
2. Connect the tube set with a fluid bag.
3. If necessary, open the clamps on the fluid bag and press the START/STOP key to
completely ventilate the tube set.
4. After ventilating the tube set, press the START/STOP key again.
Performing the pressure measuring
test
• Press the "Reduce Pressure" (Fig. Front of the device [
}
22]
(11)
) and
"WASH" (Fig. Front of the device [ } 22]
(9)
) keys simultaneously for 3 seconds.
• Set the display to "P" by pressing the "Increase Pressure" (Fig. 5-1 Front of the
device [ } 22]
(10)
) or "Decrease Pressure" key (Fig. 5-1 Front of the device [ } 22]
(11)
).
• Press the START/STOP key to confirm.
• Hold the fluid-filled tube end with the Luer Lock connection exactly 1 m higher
than the pressure chamber of the tube set.
• Read the measured pressure value. The value should be 74 ±5 mmHg.
• Exit test mode by pressing the WASH key.
The familiar nominal pressure display is now depicted again in normal operating
mode.
