6.4.3 Water Density Calibration
NOTE
Make sure that the temperature reading is calibrated before starting the water calibration.
The high end calibration of the density measurement is normally done with tubes filled with water, but
any other liquid with well-known density can be used as well.
In the automatic mode the unit performs an automatic calibration, assuming that the tubes are filled
with water.
In the manual mode the three parameters temperature, tube frequency and reference density can be
altered individually. This is necessary if the water calibration is performed with a liquid with a density
different than water. In that case make first the automatic calibration and then override in the manual
calibration the density value by the density of the medium used for calibration.
Before starting an automatic calibration, make sure that the TCM is completely filled with the test
medium. Any pollution (air bubbles, solid particles or rests of other liquids) will spoil the calibration.
