INFRATHERM pyrometer ISR 50-LO

The open / save button enable to store and recall own pyrometer configurations.
„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
section 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
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- or ratio-mode)
• emissivity
ε
or emissivity slope K, depending on
the adjusted measuring mode
• 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 warning level and switch-off level can be set in
this window.
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.
Relative signal: In ration mode the bar graph “relative signal” shows the intensity of the current measuring
signal (see also 9.1.2 Signal strength as bar graph). Additionally this value is shown directly under the bar
as percent value. A wrong adjustment of the emissivity slope K results in relative signals above 100%, in this
case K has to be adjusted correctly.
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.
Switch-off level: If the signal strength falls below the entered value for the switch-off level, the pyrometer
interrupts the measurement and displays 1° below of beginning of the temperature range (at a temperature
range of 800 ... 2500°C this would be 799°C). See also 9.6 Switch-off level).
