Measuring period
Now the sample is heated to the selected temperature. The current heating temperature is
shown in the digital display (F).
In the diagram (G) the current total amount of water is shown in [mg]. That means both the
amount of water from the sample and the amount of water from the ambient air introduced
during the filling procedure are displayed.
The duration of the test depends on the type of sample and the amount of water contained
and is between 12 – 40 minutes. After a time dependent on the measurement process (mostly
500 seconds), a display (D) of the relative humidity of the material sample appears as a
percentage. This is a prognosis that interpolates the function of the water increase over time.
Only when the HydroTracer has finished the measurement the result will be displayed
correctly.
Furthermore are shown, the time at the start of the measurement (A), the material (B)
selected under Input Mask 1 and the button (C) to terminate the current measurement
prematurely and the selection menu (E) which is only displayed after the measuring end.
