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 13, 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:
• pouring temperature of last reading, graphically and numerically
(current temperature if the pyrometer is used in another mode than pouring stream)
• file size and quantity of the recorded values of the current measurement recording
(file size and quantity of the measurement values of the current measurement recording if the
pyrometer is not in pouring stream mode)
• measuring mode (mono mode, ratio mode or metal mode)
• emissivity slope K or emissivity ε , depending on the measuring mode
• the internal temperature of the instrument (T
int
)
• minimum (T
min
) and maximum values (T
max
) during temperature recording
strength of the relative signal
The measuring mode, depending of this the emissivity or emis-
sivity slope and values for the warning 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 values in the
white fields on the left and right 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 win-
dow or by dust in the filed 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 meas-
ured intensity compared 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 results in relative sig-
nals above 100%, in this case K has to be adjusted correctly,
see 8.2
Emissivity
ε
/ emissivity slope K ).
Additionally to the bar graph of the relative signal the warning
level and the switch-off level are indicated as vertical lines in
colors corresponding to the windows below.
