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: 824°C).
• If you press “Emi: 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 which occurs with the new
temperature. This is displayed immediately and can be used for further temperature
measurement.
10.9
Measurement online trend
This window displays:
• temperature as graphical diagram
• current temperature
• quantity of the measured values
and file size of the current meas-
urement
The example shows a sample reading over
the period of approx. 12 seconds with a tem-
perature range between 0 and 300°C. The
final temperature (at the end of the reading) is
115.3°C.
If the pyrometer is
equipped with a laser tar-
geting light this can be
switched on or off.
• 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 tempera-
ture to keep the file size small.
• With “Scaling trend“ the view of the temperature 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.
10.10 Listing (analyzing)
For analyzing the measured values in
this field all measured data appears in
a numeric list.
The date beside the time gives more exactly
values to see what happened on time units
smaller 1 s. The value specifies the time in sec-
onds after midnight (0:00 h). The amount of data
depends on the frequency that readings were
taken (settings at 10.13 PC sampling rate). As
the amount of data increases, so does the
amount of storage space required to save it. In
order to save room, all .i12 data files are stored
by a binary code.
