RST board
This screen allows the user to test the RST line and RST board operation, and to linearize the
following parameters:

Atmospheric temperature.

Temperature of the sampling head.

Relative humidity at time of sampling.
For each parameter, it is possible to modify the A and B values.
For each X parameter, the value indicated on the left is the signal value stated in mV, from which it is
necessary to substract the reference voltage value. The value indicated on the right is the
corresponding value stated in the standard measurement unit.
The Head heating field is used to test the heating control of the head. To activate this control, press
down the [

] key in order to switch OFF to ON.
The Other cmd. field is used to test the operational control, when it is available on the RST board. To
activate this control, press down the [

] key in order to switch OFF to ON.
REMARK : During the first starting up, a test report is provided with the meteo sensors of the RST
line. The A and B factors enabling to linearize the relative humidity value, stated in %, can
be calculated with the help of the following table :
