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.

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.

3 Controls and Installation
12-pin connector
Pin assignment
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 8, Reference numbers).
Attention:
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.
When connecting the power supply, ensure the polarity is correct.

*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.

3.2 Sighting
Viewfinder Adjustment Ring
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.
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:
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.
The instrument is equipped with a class II laser

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.
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.

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.
IGA 6/23 Advanced Manual Controls and Installation · 20
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: 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.
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 5, Software InfraWin).
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.

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 (t90)
The response time t90 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.
°C
°C
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

4.6.1 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
is set to AUTO.
clear
Double Storage
Mode:
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.
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.

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.
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.
0 … 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.

4.9 Device Address
Settings:
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: 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
Settings:
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
placed in an area with a higher wall temperature (e.g. inside a furnace), the measurement might
be falsified (probably too high temperature indication). This influence can be compensated by
presetting the ambient temperature of the object (presetting within the measuring range of the
instrument). After switching over to “man” the corresponding data field T
is activated so that
amb
the ambient temperature value can be entered.
Attention: It has to be considered that this method only improves the results if the
ambient temperature at the place of the measured object is always constant and the
emissivity is well known.

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.

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%)

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.
