2.6.5 Scanning Mirror
The scanning mirror unit SCA 5 allows the measured object to be scanned over a certain range. The measuring beam of the pyrometer moves straight in one line across the object and collects temperature data of this line. This is useful when used in combination with the maximum value storage (peak picker) to measure objects which move out of the target area. The scanning angle of the mirror is 0 to 12° and the scanning frequency 0 to 5 Hz. Both values are easily adjustable at the scanner.
Scanning Mirror
2.6.6 Flange System
The flange system is a modular mounting system to fix the pyrometer on furnaces, vacuum chambers, etc.
Schematic drawing of the flange system
It can consist of e.g. mounting support, tube support with air purge and flange and an open or closed ceramic sighting tube. The mounting support can be equipped with a quartz window for vacuum applications. It may consist of an equipment rack, flange, and an open or closed ceramic tube. The equipment rack can be equipped for vacuum applications with a fused silica.
2.7 Transport, Packing, Storage
With faulty shipping, the instrument can be damaged or destroyed. To transport or store the instrument, please use the original box or a box padded with sufficient shock-absorbing material. For storage in humid areas or shipment overseas, the device should be placed in welded foil (ideally along with silica gel) to protect it from humidity.
The pyrometer is designed for a storage temperature of -20 to 80 °C with non-condensing conditions. Storing the instrument out of these conditions can cause damage or result in malfunction of the pyrometer.
ISR 6 Advanced Manual Introduction ∂ 13
3 Controls and Installation
3.1 Electrical Installation
The pyrometer is powered by 24 V DC ± 25% (very well stabilized, ripple max. 50 mV). It is important to ensure correct polarity when connecting the device to the power supply.
To meet the electromagnetic requirements (EMV), a shielded connecting cable must be used.
LumaSense offers connecting cables, which are not part of the standard scope of delivery.
The shield of the connecting cable has to be connected only on the pyrometer’s side. If the connecting cable is extended, the shield of the extension also needs to be extended. The shield must be open on the power supply side (switch board), to avoid ground loops.
The connecting cable has wires for the power supply, interface, analog output, external laser switch, and external clear of maximum value storage via contact and 12 pin connector. The cable includes a short adapter cable with a 9-pin D-SUB connector. This connector may be used in combination with the RS485 to USB adapter.
Once the instrument has been connected to the power supply, it is immediately ready for use.
Although it does not need to be warmed up, it does need to run for approximately 15 to 30 minutes before achieving full accuracy. The instrument can be switched off by interrupting the power supply or unplugging the electrical connector.
Attention: When connecting the power supply, ensure the polarity is correct.

The connector pin J can be used for 3 different functions:
1. External clearing of the maximum value storage:
When the pyrometer is in operating mode, pin J can be used for external clearing of maximum value storage. When external clearing is selected from the t stored maximum value.

The function “external clearing” is triggered with the following conditions:
∂
The clear time is set to “extern”.
∂
The “dirty window” warning system is switched off. This can be done through the
InfraWin software in the “color-bar” window.
∂
The warning level “dirty window” must be set to 0%.
2. Hold function:
When the hold function mode is activated, the current temperature reading is frozen as long as pin J and pin K are connected. (See section 4.6 for clear time for the maximum value storage).
3. “Dirty Window” Warning system:
The pyrometer is equipped with a “dirty window” warning system. The accuracy of the pyrometer will be seriously affected if the lens is not clean and the sight path is obscured by dirt, process material, smoke or steam (this can also happen if the object is smaller than the spot size of the pyrometer).
To avoid incorrect measurements, a warning signal can be set to detect when the signal level becomes too low or reaches a certain level. When activated, a built in relay (max.
continuous current 0.4 A) connects pin J to pin K (power supply voltage).
The setting of the warning level (0 to 99%) can be done through the “color-bar” window of the InfraWin software. If the warning level “dirty window” is set to 0%
(factory setting), the “dirty window” warning system is switched off and pin J can perform one of the functions of “external clearing” or “hold”.
The “dirty window” warning system is triggered with the following conditions:
∂
The clear time is not set to “extern” or “hold”.
∂
The pyrometer is operating in “2-color mode”.
3.1.2 Connecting the pyrometer to a PC
The pyrometer is equipped with an RS485 serial interface. With the RS485, long transmission distances can be realized and the transmission is, to a large extent, free of problems. The RS485 also allows several pyrometers to be connected in a bus system.
If an RS485 connection is not available at the PC, it can be accomplished using the RS485 to USB connector. When using a RS485 to USB adapter, make sure that the adapter is fast enough to receive the pyrometer’s answer to an instruction of the master. Most of the commonly used adapters are too slow for fast measuring equipment, so it is recommended to use the
LumaSense adapter (order no. 3 826 750).
ISR 6 Advanced Manual Controls and Installation ∂ 15
3.1.3 Connection to RS485
Half-duplex mode: A1 and A2 as well as B1 and B2 are bridged in the 12-pin round connector of the connecting cable, to prevent reflections due to long stubs.
RS485 Bus System
It also safeguards against the interruption of the RS485 Bus System should a connecting plug be pulled out. The master labels mark the connections on the RS485 converter. The transmission rate of the serial interface in Baud (Bd) is dependent on the length of the cable. Values between
1200 and 115200 Bd may be set.
3.1.4 Connection schematic for analyzing devices
For temperature indication of the pyrometer, LumaSense offers pure indicators (series DA 4000).
LumaSense also offers indicators with features to change pyrometer parameters (DA 6000 and
DA 6000-N) as well as a fast digital PID controller PI 6000.
Digital Display Parameterizing Indicator Digital Controller
Additional analyzing instruments, including LED digital displays only need to be connected to a power supply and the analog outputs of the pyrometer (exception: the digital display DA 6000 can also be connected with its serial interface, whereas the digital display DA 6000-N has to be connected with its serial interface).

Controls and Installation ∂ 16
Instruments like an analog controller or printer can be connected to the display in a series as shown above (total load of resistance max. 500 Ohm).
3.2 Sighting
The ISR 6 Advanced can be purchased with Through-Lens Sighting or with a Laser targeting light. These sighting options allow you to easily align the pyrometer to the measuring object.
3.2.1 Viewfinder
The ISR 6 Advanced can be equipped with a viewfinder which offers through-lens sighting. The viewfinder is true-sided and parallax-free. A circle marks the position of the measuring spot, but not the exact spot size.
Warning: To ensure eye protection, make sure you use the shaded filter when viewing objects with temperatures of 1500 °C or higher.
The viewfinder is equipped with an adjustable eye-protection filter, which allows you to view hot objects without exposing your eye to high intensity light. When you are viewing hot objects, turn the adjustment ring on the viewfinder so the filter will let in less light.
When you are viewing low temperature objects, turn the viewfinder adjustment ring so the filter will let in more light.
Note: You can turn the adjustment ring on the viewfinder in both a clockwise and counterclockwise direction to change the filter from light to dark.
3.2.2 Laser Targeting Light
The ISR 6 Advanced can be equipped with a laser targeting light to assist with aligning the pyrometer to the measuring object. The laser targeting light is a visible red light with a wavelength between 630 and 680 nm and a maximum power of 1 mW. The laser is classified as product of laser class II.
The laser spot marks the center of the measuring spot on the target. The diameter does not correspond to the spot size. The smallest diameter of the laser spot approximately indicates the measuring distance.
Never look directly into the laser beam. The beam and spot can be watched safely from side.
Also make sure that the beam will not be reflected into eyes of people by mirrors or shiny surfaces.
The laser targeting light can be switched on and off by pressing the button of the rear cover of the housing.
The laser targeting light can also be switched on and off by using an external contact (see section
3.1.1 “Connector Pin Assignment”) or through the InfraWin software. If it is not switched off by one of the above-mentioned methods, it will be switched off automatically after approximately 2 minutes.
To prevent damage to the laser, the targeting light is also switched off automatically if the internal temperature of the pyrometer exceeds 61 °C. It can only be used again once the temperature falls below 61 °C.
ISR 6 Advanced Manual Controls and Installation ∂ 17
Note: The laser warning signs on the pyrometer should be easily viewable at all times, even after it has been installed.
Laser Beam Safety Warning: The instrument is equipped with a class II laser that emits radiation. To reduce the risk of injury to the eyes, do not look directly into the targeting laser and do not point the targeting laser into anyone's eyes.
3.3 Optics
3.3.1 Spot Sizes
The ISR 6 Advanced has a Vario optics, which can be manually adjusted at all distances between
210 mm and 5000 mm.
The table of spot sizes in relation to measuring distance shows examples of the pyrometer’s spot size M [mm] in relation to the measuring distance a [mm] (min. 90% of the radiation intensity).
Increasing or decreasing the measuring distance will change the spot size.
Aperture D for all temperature ranges is 13 to 15 mm with the aperture being the effective diameter of the lens. This is dependent on the optical setting. The largest value applies to a very small measuring distance, while the minimum value applies to the largest measuring distance.
Note: In the 1-color (mono) mode, the pyrometer can measure objects at any distance
(whether focused or non-focused). However, the object has to be bigger than or at least as big as the spot size of the pyrometer in the measuring distance.
In the 2-color (ratio) mode, the object can be somewhat smaller than the spot diameter.

Focused spot sizes between the listed distances can be found by linear interpolation between the listed values. For example, for range 600 to 1400 °C, the spot size at 1600 mm distance would be about 16 mm.
Note: Effective aperture D for all temperature ranges is 12 mm (focused to longest distance) to 16 mm (focused to shortest distance).
3.3.2 Optional Integrated Line Optics
Besides the standard optical heads these pyrometers are optionally also available with integrated line optics. The line optics feature a special spot in shape of a line and provide additional advantages for some applications such as wire production or pouring stream measurements.
The orientation of the line spot is vertical for MB 14
(wire move horizontally).
The orientation of the line spot is horizontal for MB 25
(pouring stream runs vertical).

3.3.3 Deviation from the focused measuring distance
Spot sizes for non-focused distances (shorter or longer than the focused distance) may be calculated by using the formula below.
Formula for Calculating Spot Sizes
The InfraWin software also includes a Spot Size Calculator that calculates the data for the non-focused regions, if you enter the values of aperture D, focused measurement distance a, and focused measuring field diameter M as found in the above table (see section 3.3.1).

3.3.4 Adjusting the required measuring distance
The measuring distance can be set using the Focus
Adjustment Screw on the back of the device. The focused distance value can be adjusted at all distances between 210 mm and 5000 mm. To focus, turn the focus adjustment set screw to make the target image appear sharp and clear.
The LED Distance Indicator Light (labeled mm) will turn red and the approximate focused measuring distance in mm will automatically be shown on the Digital Display for a few seconds after making an adjustment using the Focus Adjustment Set Screw.
Note: The optics are manually focusable with a measuring distance of a = 210 to
5000 mm.
Note: Turning the focus adjustment screw counterclockwise will shorten the measuring distance.
Turning the focus adjustment screw clockwise will lengthen the measuring distance.

4 Settings / parameter descriptions
The pyrometer is equipped with a wide range of settings for optimal adaptation to the required measuring condition and to measure the temperature correctly.
The digital PC interface allows you to exchange data with a PC either by using the supplied InfraWin software or by using the Universal Pyrometer Protocol (UPP) commands with your own communication program (see Chapter 7 for the UPP Data
Format commands).
Selecting the pyrometer parameters window shows the current settings of the pyrometer. You can change a value by typing a value in an input box or by selecting a preset value from the list field.
The following settings can be made through the RS485 to USB connection.
4.1 Temperature Display
The Digital Display on the back of the pyrometer will show the temperature measurement in either °C or °F. You can select which temperature scale you wish to use through the InfraWin software or by using the UPP Data Format commands.
The Measuring Value can also be viewed at any time through the InfraWin Software or by using the UPP Data Format commands.
4.2 Emissivity ε
Different materials have different emissivities ranging between 0% and 100%. The emissivity is also dependent upon on the surface condition of the material, the spectral range of the pyrometer, and the measuring temperature. The emissivity setting of the pyrometer has to be adjusted accordingly.
Emissivity settings between 20% and 100% can be established through the InfraWin software or by using the UPP Data Format commands.
Note: Emissivity δ Settings: 5% to 100% in steps of 1/1000 (1-color mode).
4.3 Emissivity Slope K
In 2-color (ratio) mode, the pyrometer is measuring simultaneously with 2 sensors in adjacent wavelengths. It calculates the temperature by ratioing the radiation intensities of the two wavelengths. This ratio technique eliminates a number of factors that degrade the accuracy of conventional 1-color instruments. For example, with ratio pyrometers, measurement is independent of emissivity in wide areas. They are also unaffected by dust in the field of view and unaffected by dirty viewing windows or lenses, etc. as long as these disturbances are “grey”
(not colored).
In some cases the emissivities of the two wavelengths can differ so that it is necessary to correct the ratio of the two emissivities (K = δ1 / δ2) to get a correct temperature reading. This correction can be done by adjusting the emissivity slope setting K using the InfraWin software or the UPP data format commands.
The K-factors of metals are normally slightly higher than 1. For a correct measuring result, it is recommended that you make a comparison test. This comparison test may be performed by using a thermocouple probe or by knowing one process temperature point precisely from other
ISR 6 Advanced Manual Settings / parameter descriptions ∂ 21
sources. The K-factor can then be adjusted until the pyrometer shows the same temperature value.
The ISR 6 is factory calibrated for graybody targets that exhibit equal changes in emissivity within its two spectral bands.
Note: Emissivity Slope K Settings: 0.800 to 1.200 in steps of 1/1000 (2-color mode).
4.3.1 Slope Adjustment
In some cases the emissivities of the two wavelengths can differ so that it is necessary to correct the ratio of the two emissivities (K = δ1 / δ2) to get a correct temperature reading. This correction can be done by adjusting the emissivity slope setting K using the InfraWin software or the UPP data format commands.
The K-factors of metals are normally slightly higher than 1. For a correct measuring result, it is recommended that you make a comparison test. This comparison test may be performed by using a thermocouple probe or by knowing one process temperature point precisely from other sources. The K-factor can then be adjusted until the pyrometer shows the same temperature value.
The ISR 6 Advanced is factory calibrated for graybody targets that exhibit equal changes in emissivity within its two spectral bands.
4.3.2 Temperature Errors Cause by Non-Graybodies
A graybody target has emissivity that is the same at each of the two wavelengths used for measurements and is constant throughout the temperature range. The ratio of the emissivities,
δ1 / δ2= 1 and stays constant regardless of the target temperature. When a target deviates from this, that is when δ1 / δ2 does not equal 1.0 and a slope adjustment is required. For many materials, this is a one-time adjustment.
The following table illustrates the ISR 6 reading errors that can occur when the slope setting differs from the actual material emissivity ratio.

ISR 6 Advanced Manual Settings / parameter descriptions ∂ 22
The table shows typical errors that can result when the emissivity of one wavelength differs from the other wavelength by only 1%. The errors can get quite large as temperatures increase.
This error can be much larger than a 1-color IR pyrometer would produce for 1% emissivity change. Therefore, it is important to select the proper mode (2-color vs. 1-color) on the ISR 6 to measure a specific material.
Another source of error is dust or smoke in the optical path which alters the transmission in one wavelength more than the other. If the “dust” transmits 1% less energy at wavelength 1 than at wavelength 2, the error table above also applies. Since not all smoke, dust, or dense steam transmits equally at each wavelength, errors may become larger than expected for a 2-color instrument. Usually the smoke and dust are the result of the material being processed and can be cleared from the sight path by a fan or air purge tube.
In some materials, the emissivity may change at different rates with material temperature. Some materials exhibit great changes in emissivity with temperature or time as oxidation modifies the surface finish of the material. Such materials are not suited for measurement with 2-color instruments. When problems are compounded with spectrally absorbing dust or smoke
(described above), obtaining reliable temperature readings with any 2-color instrument may be impossible. In cases like this, a single color instrument using the shortest wavelength possible would be the better choice. If this problem is encountered, switch the ISR 6 to 1-color mode. In some situations, the single color mode will outperform the ratio mode.
4.4 Transmittance σ
Transmittance is a parameter that can compensate for signal loss due to external windows etc.
For example, if the emissivity of the material is 0.6 and the transmittance of an additional window is 0.9, then the product would be 0.54 which is well inside the allowed range.
The product of transmittance and emissivity (
σ
x
δ
) must not be less than 20%
−
Note: Transmittance σ Settings: 5% to 100% in steps of 1/1000 (1-color mode)
4.5 Response Time (t
90
)
The response time t
90
is the time interval for the analog output of the pyrometer to go from a low temperature value up to 90% of the temperature step to a high value when measuring an abrupt increase from said low to said high temperature.
Independently of this, the pyrometer performs a measurement every 10 ms and updates the analog output. Slower response times can be used to achieve a constant temperature reading for measuring objects that have rapidly fluctuating temperatures.
The response time is set using the InfraWin software or by using the UPP Data Format commands. When the setting is set to min., the ISR 6 Advanced operates using a time constant of <2 ms (with dynamic adaption at low signal levels). The response time can be extended to
0.01 s; 0.05 s; 0.25 s; 1 s; 3 s; 10 s.
Note: Settings for Response Time t

: min, 0.01 s; 0.05 s; 0.25 s; 1 s; 3 s; 10 s
4.6 Clear Peak Memory (t
CLEAR
)
The integrated maximum value storage is activated when the parameter tclear is set to something other than “OFF” or “HOLD”.
ISR 6 Advanced Manual Settings / parameter descriptions ∂ 23
If the maximum value storage is switched on, the highest last temperature value will always be displayed and stored. As such, it may be beneficial to periodically clear and reset the stored maximum values in order to obtain new temperature readings.
This storage also has to be cleared at regular intervals when fluctuating object temperatures cause the display or the analog outputs to change too rapidly or when the pyrometer is not constantly viewing an object to be measured.
Note: Settings for Clear Peak Memory t
CLEAR
25.0 s, EXTERN, AUTO, HOLD
: OFF, 0.01 s, 0.05 s, 0.25 s, 1.0 s, 5.0 s,
4.6.1 Single and Double Storage Modes
Depending upon the selected settings, the maximum value storage will either work in single storage mode or in double storage mode.
Single Storage
Mode:
Single storage mode is used when you want to reset the stored value using an external impulse via one contact closure from an external relay (such as between two measured objects). The relay contact is connected directly to the pyrometer between pins J and K. This mode allows a new value to be established after each impulse from the reset signal. Single storage mode also comes into effect when the Clear Peak Memory t clear
is set to AUTO.
Double Storage
Mode:
Double storage mode comes into effect when selecting one of the reset intervals. This mode utilizes two memories. With the first memory, the highest measured value is held and is deleted alternately in the time interval set (clear time). The other memory retains the maximum value throughout the next time interval. The disadvantages of fluctuations in the display with the clock frequency are thereby eliminated.
Note: The maximum value storage setting coincides with adjustments made to the response time.
The response time setting (working like a low-pass filter) is applied first. After that, the maximum storage is processed. So when using both, the maximum storage takes the peak of the signal that was previously smoothed by the response time filter.
So when using both, the maximum storage takes the peak of the signal that was previously smoothed by the response time filter.
4.6.2 Clear Time Settings
The following settings are available through the InfraWin software or by using the UPP data format commands.
OFF When set to OFF, the maximum value storage is switched off and all new temperature values are measured but not stored.
0.01s…25.0s
EXTERN
If the clear time is set between 0.01 s and 25.0 s, the maximum value is held in double storage mode. After the entered time, the value will be cleared alternately from one of the storages, while the value of the other storage is shown.
With the external clearing function, the storage operates in single storage mode. The values are immediately cleared from the storage by contacting the wires connected to pins J and K, if the EXTERN mode was selected.
ISR 6 Advanced Manual Settings / parameter descriptions ∂ 24
AUTO
HOLD
The AUTO mode is used for discontinuous measuring tasks. For example, when objects are being transported on a conveyer belt and pass the measuring beam of the pyrometer only for a few seconds. In this case, the maximum value for each object has to be obtained.
With the AUTO mode, the maximum value is stored until a new hot object appears in the measuring beam. The temperature, which has to be recognized as “hot” is defined by the low limit of the adjusted sub range.
The stored maximum value will be deleted once the temperature of the new hot object exceeds the low limit of the sub range by 1% (transition in positive direction) or by at least 2 °C. This is also valid if the sub range equals the basic range.
The HOLD function allows you to freeze the current temperature reading at any moment. This feature is activated using an external switch that has been connected between connector pins J and K.
The temperature reading will remain frozen as long as the contact remains closed.
4.7 Analog Output
The analog output has to be selected according to the signal input of the connected instrument
(controller, PLC, etc.). If 4 to 20 mA is set, the analog output gives 3.9 mA for temperatures below lower range limit.
Note: Settings for Analog Output : 0 to 20mA or 4 to 20mA
4.8 Relative Signal Strength
Relative signal strength stands for the product of emissivity, surface coverage, and transmission of the material between the object and the pyrometer. Refer to Section 4.8 for more information on Relative Signal.
4.9 “Dirty Window” Warning
The ISR 6 Advanced pyrometers are equipped with a warning level “dirty window” monitoring system. A correct temperature measurement might be impossible if the ratio pyrometer is working at a too low signal level. To avoid these wrong measurements in advance, a warning signal can be set to a certain contamination level. A built-in relay switch can be used to switch to a warning signal when the incoming radiation becomes too low.
The warning level can be set between 0 and 99%. 0% means the “dirty window” warning system is switched off (factory setting) and the relay can perform the function external clearing of maximum value storage, when it is activated (see section 4.6.2 Clear Time Settings).
Note: Settings for “Dirty Window” Warning: 0 (off) to 99%.
4.10 Minimum Intensity Switch-Off Level
The minimum intensity switch-off level is a function that is used to avoid measuring errors caused by signals which are too low. This may e.g. be caused by a dirty viewing window, dust in the field of view, or when the spot is not filled by the measuring object.
Note: Settings for Minimum Intensity Switch-Off Level: 2% to 50%
ISR 6 Advanced Manual Settings / parameter descriptions ∂ 25
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 you to program all pyrometers at the same time, regardless of the addresses that have already been assigned. If the address of a pyrometer is unknown, it is possible to communicate with it using the global Address 99 (connect only one pyrometer).
ISR 6 Advanced Manual Settings / parameter descriptions ∂ 26
4.14 Focused Distance
The focused distance value can be adjusted at all distances between 210 mm and 5000 mm using the Focus Adjustment
Screw on the back of the device.
The LED Distance Indicator Light will turn red and the focused measuring distance in mm will automatically be shown on the Digital Display within a few seconds of making an adjustment using the Focus Adjustment Set
Screw.
The focused distance can be viewed at any time through the InfraWin software or by using the
UPP Data Format commands.
4.15 Baud Rate
The transmission rate of the serial interface in Baud (Bd) is dependent on the length of the cable. A maximum cable length for 19200 Bd with RS485 is 2 km. The baud rate is reduced by
50% if the transmission distance is doubled.
Note: Settings for Baud Rate: 1200, 2400, 4800, 9600, 19200, 38400, 57600, or
115200.
4.16 Pyrometer Internal Temperature
The internal temperature of the pyrometer can be read through the PC interface using the
InfraWin software or by using the UPP Data format commands. It is a few degrees higher than the ambient temperature due to the heat generated by the electronics.
When using the Laser Targeting Light, the targeting light is switched off automatically if the internal temperature of the pyrometer exceeds 55 °C. This safety feature is used to prevent damage to the laser. It can only be used again once the temperature falls below 55 °C.

6 Maintenance
6.1 Cleaning ISR 6 Window
Because there are no moving parts in the ISR 6, the only regular maintenance required is a periodic inspection of the front window for build-up of foreign particles which, in time, can influence the energy received by the instrument. The ISR 6 has a “Dirty Window” warning alarm feature that can measure the current window/optical path transmission and provide a contact closure alert when the window transmission falls below the user set point.
The ISR 6 window is not water soluble and; therefore, can be cleaned with standard lens tissue dampened with a camera-store lens-cleaning solution. A soft blower/brush (also at camera stores) should be used to remove any grit on the window before you rub the lens with lens tissue and solution.
Attention: NEVER CLEAN THE ISR 6 WINDOW WITH A DRY TISSUE OF ANY KIND!
The only time dry lens tissue may be used is to dry a window which has already been cleaned with wet lens tissue.
6.2 Calibration
LumaSense calibrated your pyrometer at the factory and delivered your instrument with a
Works Certificate. Normally we advise against changing the factory set calibration. If you believe that the calibration may have changed, perhaps because your operating environment is severe, an approximate field (on-site) calibration is possible. You have the choice of an on-site calibration or arranging a more precise calibration at the LumaSense factory.
6.2.1 Laboratory Calibration
Contact LumaSense for information about calibration at the LumaSense factory. For most of our customers who do not have large numbers of infrared thermometers in service, we recommend that our laboratory be chosen to do calibration. When you have many infrared thermometers, you may find it most convenient and economical to have your own calibration laboratory.
LumaSense has a variety of blackbody calibration sources including very economical ones.
Among these you may find the source most suitable for your own laboratory.
6.2.2 On-Site Calibration
See the Chapter 9: Troubleshooting in this manual before attempting to perform your own calibration. The instrument was calibrated at the factory to its original accuracy as stated.
Nearly all erroneous temperature readings are caused by application problems such as:
∂
Emissivity factor: Carefully read “Emissivity Slope K” found in section 4.2 of this manual for information on this topic. Also use the InfraWin “K: AutoFind” function as described in the InfraWin manual to determine the actual emissivity ratio of the target.
∂
Reflections: Unexpectedly high readings may be caused by the ISR 6 “seeing” a reflection of another hotter source, especially if the target emissivity is less than 0.8.
∂ Spot Sizes: Ensure the ISR 6 is using a proper focused distance and takes into account the spot size in relation to measuring distance.

∇
∂ 31
In the 1-color (mono) mode, the pyrometer can measure objects at any distance.
However, the object has to be bigger than or at least as big as the spot size of the pyrometer in the measuring distance.
In the 2-color (ratio) mode, the object can be somewhat smaller than the spot diameter.

7 Data format UPP (Universal Pyrometer
Protocol)
Software commands can be exchanged directly with the pyrometer through an interface using suitable communication software or by using the Test function located in the Pyrometer
Parameters window of the InfraWin software package.
The data exchange occurs in ASCII format with the following transmission parameters:
• The data format is: 8 data bits, 1 stop bit, even parity (8,1,e) no handshake;
• The device responds to the entry of a command with output (such as the measuring value) + CR (Carriage Return, ASCII 13), to pure entry commands with ok + CR, or no +
CR.
• Every command starts with the 2-digit device address AA followed by two lower case command letters and finished with CR.
Example Read Command: Entry: “00em“ + CR
The emissivity setting (δ) of the device with the address 00 is returned.
Answer: “0970“ + ;CR= means Emissivity = 0.97 or 97.0%
• The ASCII parameter “X” indicates a change to be made in a parameter. When used, the command contains the new value.
Example Write Command: Entry: “00emXXXX“ + CR
The parameter used for the emissivity setting (δ) with the address 00 is changed.
Answer: “00em0853“ + ;CR= changes the Emissivity to 0.853 or 85.3%
∂
A “?” after the lower case command letters answers with the limits of the respective settings (only at setting commands, not at query commands).
Example Read Limits Command: Entry: “00em?“ + ˜CR!
Answer: Could be 00501000 + <CR>, which means that E can vary between 0.050 and
1.000 (or 5% and 100%)

Additional instruction for the RS485 interface:
Requirements to the master system during half-duplex operation:
1. After an inquiry, the bus should be switched into a transmission time of 3 bits (some older interfaces are not fast enough for this).
2. The pyrometer's response will follow after 5 ms, at the latest.
3. If there is no response, there is a parity or syntax error and the inquiry has to be repeated.
4. After receiving the response, the master has to wait at least 1.5 ms before a new command can be entered.

9 Troubleshooting
Symptom Probable Cause
No analog output even if the display shows a temperature above lower range limit
Temperature reading differs between built-in display and external instrumentation
Reversed leads to ISR 6.
Reversed leads to other instruments in the current loop.
Open circuit in lines connecting all instruments in current loop.
Total burden higher than 500
Ohms
Insufficient supply voltage (See wiring diagram).
Pyrometer output setting differs from external instrument’s input setting
Temperature readings are too low
Target size too small.
Target is not at correct focus distance.
Incorrect alignment of the pyrometer to the object.
Comments
The ISR 6 is diode protected if power leads are reversed.
See Section 3.1.
Check the 0 to 20 mA or
4 to 20 mA on both sides
Check the sub range setting on pyrometer against the range setting on the external instrument
See Section 3.1.1.
With small target/close focus models, aiming may require X-Y positioning table for fine adjustment during aiming.
Realign pyrometer in 1-channel mode (mono) to achieve the maximum temperature signal.
See Sections 4.9 and 6.1
Dirty window or lens.
Target temperature too low.
Target emissivity much lower than expected.
Even 2-Color instruments depend on actual target emissivity to supply sufficient energy to the sensor.
See Sections 4.2, 4.3, 4.4, 4.8, and 6.1
Faulty ISR 6 Contact LumaSense.
See Section 1.5.
ISR 6 Advanced Manual Troubleshooting ∂ 39
Symptom
Temperature readings are too high
Probable Cause
Targets hotter than expected.
(This often happens with first time infrared Pyrometer users).
Comments
Verify target temperature with contact type method.
(Thermocouples may not accurately determine surface temperature due to “heat sink” effect).
Target size is too small
The measurement is influenced by reflections of hot machine parts
If target emissivity is less than 1, reflections from nearby hot objects will influence readings.
Incorrect spectral response for application. ISR 6 may be
“seeing” through target.
Electrical noise in lead wires caused by intense magnetic fields and/or improper selection of interconnecting cable and/or cable run in same conduit as AC power lines.
Lens or window clouding up.
See Section 3.1.1.
Use mechanical accessories to avoid the influence of the interfering radiation.
Block reflection paths to see if readings drop to expected temperature.
See Technicial Specifications
Consult LumaSense for analysis.
See Section 3.1
Increase or decrease air purge rate and/or investigate other cause.
Target leaving field of view or
ISR 6 mount slipping.
Faulty ISR 6.
Contact LumaSense.
See Section 1.5
Improper grounding of cable shield and/or ISR 6 housing (or cooling jacket).
ISR 6 mounting not secure.
ISR 6 Advanced Manual Troubleshooting ∂ 40
Symptom
Noisy readings (fast fluctuations).
Laser Targeting Light fails
Probable Cause
Target moves more than 95% out of field of view. Conveyor type applications will also cause fluctuations as targets move by the field of view.
Target may be changing temperature quickly.
(Thermocouples do not respond as fast as the ISR 6).
Comments
Application may require
Maximum to be stored. Apply t clear
settings. See Section 4.6.2.
Speed of response may be slowed down
Apply t
90
settings.
See Section 4.5.
Target may be reflecting nearby objects that have fluctuating temperatures.
Loose connection in wiring.
Electrical noise lead wires caused by intense magnetic fields, improper selection of interconnecting cable.
Cable run into in same conduit as
AC power lines.
Improper grounding of cable shield and/or ISR 6 housing.
Flame or reflections of flame may be entering the field of view.
Extremely dense steam, smoke, thick dust, personnel or moving machinery intermittently blocking 95% of optical path of
ISR 6.
Non-uniform emissivity of large moving targets.
Faulty ISR 6.
The instrument‘s internal temperature is higher than 55°C.
Slower response speed is required.
Contact LumaSense.
See Section 1.5.
Use cooling jacket.
See Section 2.6.2.
