6.4.1 Temperature Calibration
For calibrating the temperature reading of the TCE8000, the medium temperature must be well known.
Before starting the calibration make sure that the temperature reading has been stable for several
minutes for making sure that the medium temperature and the temperature of the temperature sensor
are the same.

6.4.2 Air Density Calibration
NOTE
Make sure that the temperature reading is calibrated before starting the air calibration.
The low end calibration of the density measurement is normally done with empty tubes (filled with air).
In the automatic mode the unit performs an automatic calibration, assuming that the tubes are filled
with normal air.
In the manual mode the three parameters temperature, tube frequency and reference density can be
altered individually. This is necessary if the air calibration is performed with a gas with a density
different than air. 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 empty as any drop of a
liquid inside will spoil the calibration result.
