ISR 6 Advanced Manual Settings / parameter descriptions · 26
Note: Settings for Minimum Intensity Switch-Off Level: 2% to 50%
Ratio pyrometers are able to measure temperatures correctly even with very low signals. If the
signal is too low for a correct measurement, the pyrometer interrupts the measurement and
displays 1 °C below of beginning of the temperature range.
Although the factory default is set to 10%, switch-off limit can be adjusted between 2 and 50%,
depending on the application.
Note: The smaller the value, the higher the chance that daylight or reflections will
affect a correct temperature measurement.
4.11 Operating Modes
Ratio (2-color) mode is the factory default operating mode for the ISR 6 pyrometer. However,
the device can be set to mono (1-color) mode using the InfraWin software or by using the UPP
Data Format commands.
With 1-color mode, the device adjustments are simplified by
sending the emissivity corrected one channel temperature to the
analog output.
For a correct measurement in the 1-color mode, it is necessary to
adjust the emissivity using the InfraWin software or by using the
UPP Data Format commands. This emissivity is the relationship
between the emission of a real object and the emission of a
blackbody radiation source (this is an object which absorbs all
incoming rays and has an emissivity of 100%) at the same
temperature.
4.12 Sub Range
You have the opportunity to choose a sub range (minimum span 50 °C) within the basic
measuring range of the pyrometer. This sub range corresponds to the analog output.
Example: Range 700…1800 °C, Sub Range 925…975 °C.
The sub range setting also affects the maximum value storage when the Clear Peak Memory
t
clear
is set to AUTO. For more information on the t
clear
AUTO setting, refer to Section 4.6.
Note: Settings for Sub Range: Any range adjustable within the temperature range
with a minimum span of 50 °C.
4.13 Device Address
When connecting several pyrometers to one serial interface with RS485, it is necessary for each
instrument to have its own device address for communication purposes. First, it is necessary to
connect each instrument separately to give it an address. After that, all instruments can be
connected and addressed individually.
Note: Settings for Device Address:
Individual Addresses: 00…97 Global Addresses: 98, 99
Only via own communication program with interface command (not possible with
InfraWin, because InfraWin automatically detects a connected pyrometer): If parameters should
be changed simultaneously on all pyrometers, the global Address 98 can be used. This allows
