3 Controls and Installation
3.1 Electrical Installation
The IGA 6/23 Advanced is powered by a voltage of 24 V DC ± 25% (ripple < 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, switch contact, and external clearing of the maximum value storage via contact and 12-pin connector (see
Chapter
, Reference numbers).
Attention: When connecting the power supply, ensure the polarity is correct.
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.

*The connector pin J can be used for two 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 tclear dropdown menu, pin J is connected for a short time to pin K (power supply voltage) to clear the stored maximum value. The function “external clearing” is triggered when the clear time is set to “extern”.
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).
3.1.2 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
RS485 ó USB converter “USB nano“ (ref. no. 3 852 600).
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. 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. Adjusted values are from 1200 to 115200 Bd.

3.1.4 Connection of Additional Units
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).
Connection of additional units
Other 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).
IGA 6/23 Advanced Manual Controls and Installation · 17
3.2 Sighting
The IGA 6/23 Advanced can be purchased with Through-Lens Sighting (viewfinder) 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 IGA 6/23 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.
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.
Warning: To ensure eye protection, make sure you use the shaded filter when viewing objects with temperatures of 1500 °C or higher.
Viewfinder Adjustment Ring
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.
When you are viewing low temperature objects, turn the viewfinder adjustment ring so the filter will let in more light.
3.2.2 Laser Targeting Light
The IGA 6/23 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.
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.
IGA 6/23 Advanced Manual Controls and Installation · 18
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.
Push button for
Laser Targeting Light
Note: The laser warning signs on the pyrometer should be easily viewable at all times, even after it has been installed.
The laser targeting light can also be switched on and off by using an external contact (see section 3.1.1 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.
3.3 Optics
3.3.1 Spot Sizes
The IGA 6/23 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.
Note: Since these are 1-color (mono) pyrometers, they 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.
IGA 6/23 Advanced Manual Controls and Installation · 19
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: Effective aperture D for all temperature ranges is 13 mm (focused to longest distance) to 15 mm (focused to shortest distance).
Focused spot sizes between the listed distances can be found by linear interpolation between the listed values.
3.3.2 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).
3.3.3 Finding the right 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.
Note: The optics are manually focusable with a measuring distance of a = 210 to
5000 mm.

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.
All settings can be read and set only in the pyrometer parameters window of the software InfraWin. Adjusting the settings at the instrument is not possible (detailed description of the software see Chapter
Selecting the pyrometer parameters window shows the current settings of the pyrometer. Changing a value can either be done by typing a value in an input box or by selecting a preset value from the list field.

4.2 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.
4.3 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 5% and 100% can be established through the InfraWin software or by using the UPP Data Format commands.

4.4 Transmittance t
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 ( t x e
) must not be less than 5%
.
Note: Transmittance t can be set from 5% to 100% in steps of 0.1%
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.
The dynamic exposure time adjustment prolongs the exposure time at the lower range limit.
With the InfraWin software and the UPP Data Format commands it is possible to configure the dynamic exposure time.

Independently of this, the pyrometer performs a measurement every 25 µs 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 IGA 6/23 Advanced operates using a time constant of

4.6 Clear Peak Memory (t
CLEAR
)
The integrated maximum value storage is activated when the parameter t clear is set to something other than “OFF” or “HOLD”.
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.
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:
Double Storage
Mode:
Settings: off

25 s extern auto
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 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.
IGA 6/23 Advanced Manual Settings / parameter descriptions · 25
4.6.2 Clear Time Settings
The following settings are available through the InfraWin software or by using the UPP data format commands.
OFF
10 ms…25,0 s
EXTERN
AUTO
HOLD
When set to OFF, the maximum value storage is switched off and all new temperature values are measured but not stored.
If the clear time is set between 10 ms 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.
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.
Einstellungen:
0 … 20 mA
4 … 20 mA
4.8 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 150…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
.
Note: Settings for Sub Range - any range adjustable within the temperature range with a minimum span of 50 °C.
IGA 6/23 Advanced Manual Settings / parameter descriptions · 26
4.9 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.
Settings:
00
...
97
Note: 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).
4.10 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.
4.11 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.
Baud Rates can be set at 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200.
4.12 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
61 °C. This safety feature is used to prevent damage to the laser. It can only be used again once the temperature falls below 61 °C.
IGA 6/23 Advanced Manual Settings / parameter descriptions · 27
4.13 Ambient Temperature Compensation
The compensation of the ambient temperature can be set for temperatures within the basic measuring range. This compensation is only used for very few special applications. The standard setting of this parameter is “auto", because the temperature of the air around the pyrometer is normally the ambient temperature of the measured object. Should the measured object be instrument). After switching over to “man” the corresponding data field T the ambient temperature value can be entered.

Len indicates the length of the answered data string, incl. Carriage Return (Chr(13)).
IGA 6/23 Advanced Manual Software InfraWin · 30
In the lower part of the window, the connection with the preset baud rate can be checked. Here the command was sent 100 times with 19200 baud. It has taken 1.100 seconds without transmission errors.
Emi: AutoFind: If the true temperature of the measured object is known, you can calculate the emissivity of the measured object using the Emi: AutoFind function:
A measured temperature is displayed with the current set emissivity (in this example
100%) (here: 116 °C).
If you press Emi: Autofind a window will open which allows you to enter the "true" temperature (here 130 °C).
Once the temperature entry has been entered and confirmed with Calculate, InfraWin will then calculate the emissivity which occurs with the new temperature (here 79.0%). This is displayed immediately and can be used for further temperature measurement.
5.5 Measurement online trend
The measurement function allows you to access a number of input tabs located on the left side of the screen. The main or home tab is the Output
Screen. You can toggle the input tabs on and off by clicking them. This window displays:
· temperature as graphical diagram
· internal temperature of the instrument
· current temperature
· quantity of the measured values and file size of the current measurement
The example shows a sample reading over the period of approximately 15 seconds with a temperature range between 400 and 800 °C. The final temperature (at the end of the reading) is
431 °C.
The Mark Zone button allows you to color mark a temperature range for easier recognition.
The Threshold button allows you to set a temperature value as a baseline to prevent recording values above or below the baseline temperature. This allows you to keep the output file size small.
IGA 6/23 Advanced Manual Software InfraWin · 31
The Scaling Trend button allows you to scale temperature trend view.
Note: The measuring values of “measurement online trend” are automatically saved as "standard.i12". Should you need to edit the data later, you need to save the file as another .i12-file because old values are over-written when a new measurement is taken.
Files from older program versions (.i10-files) can be opened and saved as .i12.
5.6 Listing (analyzing)
For analyzing the measured values in this field, all measured data appears in a numeric list.
The column between time and temperature provides a time resolution of milliseconds. The value specifies the time in seconds after midnight (0:00 h). The amount of data depends on the frequency that readings were taken
(settings at 10.9 PC sampling rates).
As the amount of data increases, so does the amount of storage space required to save it. In order to save room, all .i12 data files are stored by a binary code.
5.7 Output .TXT file (analyzing)
The same file as under Output listing may be converted into a text file and can be easily opened, for example with Microsoft Excel. With the standard import settings, Excel automatically formats the columns accordingly (with tabs as separators).
5.8 Trend output (analyzing)
The graph’s curve depicts the temperature change over time within the specified temperature range.
Additionally, other information appears in this window; such as recorded time (x-axis) and temperature in degrees (y-axis) as well as the time and temperature at the vertical cursor line which can be dragged with the mouse.
Selecting the Trend output initially causes all the saved data to be displayed.
If the data exceeds an amount that can be reasonably represented, you may “Zoom“ in on a partial segment using the mouse (such as the segment represented in the example). Under
“Total” you can return to the representation of the entire curve.
IGA 6/23 Advanced Manual Software InfraWin · 32
Note: The last reading is saved in the standard.i12 file and automatically appears in this form upon opening Listing or Trend output.
Selecting file open with another file, the previous file will be overwritten and replaced by the standard.i12 file.
5.9 PC sampling rate (time interval between two measurements)
This function sets a time interval. After each interval, one measured value is stored on the PC. Longer time intervals will result in creating smaller stored file sizes. This function is mainly used for long term measurements.
5.10 Spot size calculator
The InfraWin Spot Size Calculator calculates the data for the nonfocused regions. To calculate data, enter the values of aperture D, focused measurement distance a, and focused measuring field diameter M as found in the documentation relating to the optics supplied with your specific pyrometer.
After entering the aperture and the main spot size, the input of interim values calculates spot sizes in different measuring distances of the fixed optics.
5.11 Search I/O Module
The I/O Module allows accessories to connect to the software and is used to trigger measurement externally or to send a signal
(like a relay) under certain conditions.

6 Maintenance
6.1 Cleaning the front window
Since the device does not contain parts that require regular maintenance, the only regular maintenance required is periodic inspection of the front window for build-up of foreign particiles. If allowed to build up, the particles can influence the energy received by the instrument.
The IGA 6/23 Advanced window is not water soluable and can be cleaned with standard lens tissue dampened with a commercially available glasses or camera lens cleaning solution. Use a soft blower/brush (available in camera stores) to remove any grit on the window before you rub the lens with lens tissue and solution.
Attention: NEVER CLEAN THE IGA 6/23 Advanced 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 IGA 6/23 Advanced 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 Chapter 9 Troubleshooting 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:
· Reflections: Unexpectedly high readings may be caused by the IGA 6/23 Advanced
“seeing” a reflection of another hotter source, especially if the target emissivity is less than 0.8.
·
Spot Sizes: Ensure the IGA 6/23 Advanced is using a proper focused distance and takes into account the spot size in relation to measuring distance. 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.
·
Obscured window: Clean the window. Refer to the cleaning window section 6.1.

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 (e) 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 (e) 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%)

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
No analog output even if the display shows a temperature above lower range limit
Symptom
Temperature reading differs between builtin display and external instrumentation
Temperature readings are too low
Temperature readings are too high
Probable Cause Comments
Reversed leads to IGA 6/23 Advanced The IGA 6/23 Advanced is
Reversed leads to other instruments in the current loop
Open circuit in lines connecting all instruments in current loop diode protected if power leads are reversed.
See section
Total burden higher than 500 Ohms
Insufficient supply voltage (See wiring diagram)
Pyrometer output setting differs from external instrument’s input setting
Target size too small
Target is not at correct focus distance
Incorrect alignment of the pyrometer to the object
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
With small target/close focus models, aiming may require X-
Y positioning table for fine adjustment during aiming
Realign pyrometer to achieve the maximum temperature signal
See Section
Dirty window or lens
Target temperature too low.
Incorrect slope adjustments
Faulty IGA 6/23 Advanced
Targets hotter than expected. (This often happens with first time infrared
Pyrometer users)
The measurement is influenced by reflections of hot machine parts
Contact LumaSense. See section
Verify target temperature with contact type method.
(Thermocouples may not accurately determine surface temperature due to “heat sink” effect)
Use mechanical accessories to avoid the influence of the interfering radiation
If target emissivity is less than 1, reflections from nearby hot objects will influence readings
Incorrect spectral response for application. IGA 6/23 Advanced may be “seeing” through target
Block reflection paths to see if readings drop to expected temperature
See Technicial Specifications
Consult LumaSense for analysis.
IGA 6/23 Advanced Manual Troubleshooting · 43
Symptom
Temperature readings are too high
Noisy readings (fast fluctuations)
Laser Targeting Light fails
Probable Cause
Faulty IGA 6/23 Advanced
Comments
Contact LumaSense. See section
See section
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

Improper grounding of cable shield and/or IGA 6/23 Advanced housing (or cooling jacket)
IGA 6/23 Advanced mounting not secure
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
IGA 6/23 Advanced)
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 inter-connecting cable
Cable run into in same conduit as AC power lines
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 IGA 6/23 Advanced
Non-uniform emissivity of large moving targets
Faulty IGA 6/23 Advanced
The instrument‘s internal temperature is higher than 61 °C
Application may require
Maximum to be stored. Apply t clear
settings. See section
Speed of response may be slowed down
Apply t
90
settings. See section
Slower response speed is required
Contact LumaSense. See section
Use cooling jacket
Note: The wavelength band of the IGA 6/23 reacts at low measuring temperatures
(below 130 °C) to incandescent lamps or very bright daylight (not valid for fluorescent tube). For a correct measurement strong external light to the measured object should be avoided.
