In the lower part of the window, the connection with the preset baud rate can be checked. Here
the command was sent 100 times with 19200 baud. It has taken 0.800 seconds without
transmission errors.
Emi: AutoFind: If the true temperature of the measured object is known, you can calculate the
emissivity of the measured object using the Emi: AutoFind function:
A measured temperature is displayed with the
current set emissivity (in this example 100%)
(here: 707.8 °C).
If you press Emi: Autofind a window will open
which allows you to enter the “true”
temperature (here 720 °C).
Once the temperature entry has been entered
and confirmed with Calculate, InfraWin will
then calculate the emissivity which occurs with
the new temperature (here 84.0%). This is
displayed immediately and can be used for
further temperature measurement.
5.5 Relative Signal
The relative signal bar graph provides and indication of the signal strength.
InfraWin Software Relative Signal Indicator
In the above image, the relative signal bar indicates a signal intensity of 25.2%. This can be
caused by the object’s emissivity, contamination of the optics or viewing window, dust in the
field of view, or a small measuring object.
Normally, this bar graph is used to monitor if the signal level due to contamination of optics or
window decreases over time. It shows the measured intensity compared to the intensity a
blackbody radiation source would have at the determined ratio temperature of the pyrometer.
The shown relative signal depends on the entered emissivity slope K (a wrong adjustment results
in relative signals above 100%).
