„1 meas.“ shows the current measuring temperature in the pyrometer parameters window for
approx. 1 second.
A click on the “Test” icon opens a window that
allows the direct communication with the py-
rometer via the interface commands (see sec-
tion 14, Data format UPP
®
).
After entering an interface command (00 is the
adjusted address ex works, “ms“ is the com-
mand “reading temperature value“) and a click
on “Send“ the following window is opened:
This window already shows the answer of the pyrometer in
1
/
10
°C. The last temperature (or actual tempera-
ture if the pyrometer is used in another mode than pouring stream) reading is 1513.8°C.
“Len“ indicates the length of the answered data string, incl. Carriage Return (Chr(13)).
In the lower part of the window the connection with the preset baud rate can be checked. Here the command
was send 500 times with 19200 baud. It has taken 4.65 seconds without transmission errors.

Measurement color bar
This window displays:
• current temperature, graphically and numerically
• file size and quantity of the measured values of
the current measurement
• measuring mode (mono- , ratio- or metal mode)
• emissivity
ε
or emissivity slope K, depending of
the measuring mode
• the internal temperature of the converter (T
int
)
• minimum
(T
min
) and maximum values (T
max
)
• strength of the relative signal
• Warning level, graphically and numerically
• Switch-off level, graphically and numerically
The measuring mode, the emissivity or
emissivity slope and values for the warn-
ing level and switch-off level can be set in
this window. The laser targeting light can
be switched on or off with the PL-button
(
).
The color bar display shows the span of the temperature
range or the adjusted sub-range. Entering temperature val-
ues in the white fields on the right and left side of the color
bar, limits for the color change of the color bar can be set.
These limits can also be changed by moving the small bar
with the PC mouse. The color bar displays temperatures
within the two limits in green color, outside the limits in red
color
The bar graph “relative signal” shows a signal weakening. This can be caused by contamination of the optics
or a viewing window or by dust in the field of view or a too small measuring object. Normally this bar graph is
used for surveillance of the level of contamination of optics or window. It shows the measured intensity com-
pared to the intensity, a black body radiation source would have at a determined ratio temperature of the
pyrometer. Precondition for this is the correct adjustment of the emissivity slope K (a wrong adjustment re-
sults in relative signals above 100%, in this case K has to be adjusted correctly). The display of the type
ISR 12-LO also shows the intensity of the relative signal if the laser targeting light is switched on.
