4. Recording the pressure value
After inserting the needle through the septum and injecting the sample, the “INJECT”- LED
goes off and LED 2 indicates that the measurement sequence has started.
Figure 6-5
It takes approx. 30 seconds up to a maximum of 4.5 minutes for the balance of the osmotic
underpressure to stabilize in the lower measuring cell filled with solvent. This balanced state is
detected by the electronics and the measurement value is shown on the digital display.
Figure 6-6
At the same time, the LED 2 and LED 3 go off and the “RESULT”- LED comes on.
This presents the measurement result, which is representative of the osmolal concentration of
the colloids (colloid osmotic pressure).
The display is in mmHg. Pressing the "cm H2O" or "k-Pascal" button will show the result in the
corresponding measurement unit. You can also select the measurement unit prior to starting
the measurement.
