5.4.2 Reference point compensation
A thermoelectric temperature measurement measures a
(thermoelectric) voltage generated by a thermoelectric cou-
ple. The value of the thermoelectric voltage depends on the
temperture difference between the measured point and the
reference point.
In order to define accurately the temperature at the measu-
red point, the temperature of the reference point must be
constant and/or known. To do so, the internal and external
reference points are differentiated.
For the internal reference point compensation, the device is
fitted with an internal temperature sensor that measures
the current temperature of the terminal. This temperature is

used to compensate the measured thermoelectric voltage.
This measuring method requires to connect the sensor with
the terminal of the display by means of appropriate com-
pensation lines. These terminals are the internal compen-
sation point.
When using the external reference point compensation, the
temperature of the reference point is maintained at a con-
stant and known value by means of appropriate measures.
The temperature sensor ist connected with the device,
which is set to the constant temperature of the reference
point, by means of a simple copper wire.
