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

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
