Warning level „dirty window“: If the signal strength falls below the entered value for the warning level, the
pyrometer switches a built-in relays which can be used to switch a warning signal (see section 9.7 Contami-
nation limit, or for the relay output section 5, electrical installation). The warning level can be set between
0 and 99%. For all settings below the adjusted value of the switch-off level the lens contamination monitoring
system is switched off (factory setting).
K: AutoFind: In addition, there is an input field K for the emissivity slope in the window. If the emissivity is
changed, the temperature change connected with this can be read off directly.
If the true temperature of the measured object
is known, you can calculate the emissivity
slope of the measured object using the "K:
AutoFind“ function:
• A measured temperature is displayed with
the current set emissivity slope (in this ex-
ample 1) (here: 824°C).
• If you press „K: Autofind “ a window will open which allows you
to enter the "true" temperature.
• Once the temperature entry has been entered and confirmed
with "OK", InfraWin will then calculate the emissivity slope which occurs with the
new temperature. This is displayed immediately and can be used for further tem-
perature measurement.

Measurement online trend
This window displays:
• temperature as graphical diagram
• current temperature
• measuring
mode
• quantity of the measured values and file size of the current measurement
The example shows a sample reading over
the period of approx. 12 seconds with a tem-
perature range between 800 and 1500°C. The
final temperature (at the end of the reading) is
1070.5°C.
• With “Mark zone” a temperature range can
color marked for easier recognition.
• Setting a temperature under “Threshold“
prevents the recording of values above or
below this temperature to keep the file
size small.
• With “Scaling trend“ the view of the tem-
perature range can be limited.
Note: The measuring values of “measurement color bar” or “measurement online trend” are
automatically saved as "standard.i12". Should you need to edit the data later, you
need to save the file as another .i12-file because old values are over-written when a
new measurement is taken.
Files from older program versions (.i10-files) can be opened and saved as .i12.
