distilled water into Positions 0-0 to rinse the baseline. You can place the calibration standard and
samples to be measured in Positions 1-4 first.
5.2 Calibrating the measurement system for determining
osmolality
Start osmolality measurement by clicking File and then selecting New Measurement-070 followed by
Osmolality Measurement.
Figure 5-1: Osmolality measurement Start screen
In the Start screen, you will be prompted to enter the measurement temperature, sampling time and
probe serial numbers. A measurement temperature of 37°C is recommended for measuring the
osmolality of aqueous solutions. The sampling time is determined in the same manner as described in
Chapter 4.1.1.2. You can enter comments.
If a calibration has already been carried out previously, the cell constant is entered and it is not
absolutely essential to perform another calibration. You can start the measurement immediately.
However, it is advisable to check the calibration occasionally. The cell constant is the result of the
calibration and indicate the number of digits that correspond to a mOsmol. After you have entered the
parameters, quit the screen dialog by clicking Next.
