2.1.4. Displayed frame rate
Off
The display frame rate corresponds to the device frame rate of the camera.
Skipping
It skips so many pictures that the set display frame rate results.
Average
The pixels are averaged out of a sequence of images. This weakens the detector noise.
Minimum
From a sequence of images, the smallest value is displayed for each pixel.
Maximum
From a sequence of images, the highest value is displayed for each pixel.
Ext.
Averaging
Is a combination of average and skipping and is used at very low display rates. The
averaging time indicates how many percent of the set frame time should be averaged.
In the remaining time, the frames are skipped (e.g., if the display frequency is 1 Hz and
the averaging time is 10%, then 100 ms is averaged and 900 ms are skipped).
The option Reduce displayed frames defines what
frame rate is used to display the image. Typically, the
specification is in Hertz (Hz, images per second). The
maximum frame rate of the imager depends on the
camera model you’re using. It is recommended to
use the default parameters of 20 Hz.
The camera supplies the software with all images at the whole time. When you using a lower display
framerate you have to decide what should happen with the rest of the pictures. Under Mode you have
several options:
optris PIX Connect – E2018-03-A
21
Note
A reduced frame rate means a less loaded computer in terms of data processing. Therefore,
please adjust the displayed frame rate according to your application as well as to the performance
of your computer.
2.1.5. Change of title bar
The Application title bar option enables the individual
setting for an own title name.
The setting Default displays the standard software
name „PIX Connect“. Using the setting User defined
you can specify an individual name. The option Instance name is important if starting several cameras and

2.1.6. Optimization of software
The display of the thermal image in the main window of the software can
be adjusted according to the performance of the computer. Choosing
the option Quality and High-speed temperature calculation the
display will be enlarged to the highest resolution, but requires a higher
computing power. Using a slow computer, it is recommended to choose
the option Performance. Is the bar placed in the middle, you get a compromise between quality and
performance.
If Keep Aspect Ratio is selected the aspect ratio will be
maintained.
The option Prevent screensaver is suppressing the
screensaver functionality of your computer.

2.4. Imager configuration
2.4.1. Calibration files
The menu Tools, Extended and Load calibration data enables to boot the calibration data for the currently
connected imager.
2.4.2. Correction of camera calibration
Due to the thermal drift of bolometers all measuring IR cameras need an offset correction every few minutes.
This correction is done by a motor driven motion of a blackened metal piece (so called flag) in the front of the
image sensor. In this way each image element is referenced with the same temperature. During those offset
calibrations thermal cameras do not measure (time is dependent on model and video mode). In order to
minimize this disturbing effect the offset correction can be initiated manually or by an external control pin at a
suitable point of time.
In the Devices and Refresh flag menu or via the Icon on the toolbar the
Flag (Shutter) can be refreshed manually.
The automatic correction of camera can also be set by defining minimum
or maximum intervals via the menuTools, Configuration and Device.
The options Flag automatic and Min. Interval control that the flag will not
be released before a given time period even though it might be required
by the imager. If the Max. Interval is defined the flag will always be
released after a certain time period even if not required by the imager.
optris PIX Connect – E2018-03-A
31
Using the option Flag operation while recording and Use flag the correction is activated even if the
Note
The manual or automatic flag functionality is not available if the flag is externally controlled, e.g. via
the process interface input (please also see 2.5).
Note
The flag can be also used to protect the detector from potentially dangerous radiation (for example
laser radiation).
Note
The detector heating (Chip temperature mode) setting is only available for the PI series because
there is no chip heater integrated for the Xi series.
camera is recording. If Avoid flag is chosen the camera will not be corrected while recording. The option
Use flag whileskipped frames is suitable at slow data capturing (3 Hz or less) as the correction will take
place automatically between two recorded images (correction time app. 250 ms).
2.4.3. Detector heating (Chip temperature mode)
The bolometer chip temperature can be set under Configuration
and Device. Standard (Floating) means that the chip heater is
off. The chip temperature results from the ambient temperature.
With Automatic, a predefined temperature is set. And a fixed chip
temperature can be set with Fixed value.
optris PIX Connect – E2018-03-A
32
2.4.4. Emissivity, transmissivity, ambient temperature
Note
In case that the emissivity and / or the ambient temperature values are controlled through the
Process Interface (PIF) the here defined values will be ignored (please also see 2.5). The display
of actual values will be shown in the status bar.
Using the menu Tools, Configuration and Device the
Emissivity and the Transmissivity (IR-window compensation)
can be set. The transmissivity is referring to the loss of radiation
if an object’s surface is measured by looking through a suitable
window.
Knowing the Ambient temperature is inevitable for a correct
temperature measurement. The ambient temperature value is
delivered by the camera’s internal sensor by default.
Alternatively, the value can be set as a fixed value.
Alternatively, the emissivity can also be changed via
the status bar in the PIX Connect software window. To do this, make a right-click on emissivity.
2.4.5. Reference temperature
The detector of the thermal imager has a thermal drift
over the time and must be corrected by self referencing.
At applications where a high measurement accuracy is
needed, the thermal image can be corrected permanently
by setting a reference temperature. Using the menu
Tools, Configuration, Device and Reference
optris PIX Connect – E2018-03-A
33
temperature several options for manual or automatic correction can be set.
Auto
The software is choosing the best way of correcting the image (offset or gain).
Offset
This kind of correction is recommended if there are big temperature differences
between the reference temperature value and the thermal image.
Gain
This kind of correction is recommended if there are small temperature differences
between the reference temperature value and the thermal image.
If there is an area within a thermal image having a constant temperature value (e.g. black body) the Source
can be defined as a Fixed value. By the option Compare with measuring area the area with constant
temperatures can be determined. The known reference value can be set within Fixed value. If the
temperatures are changing slightly within the defined area due to a thermal drift, the whole image will be
corrected by a certain factor.
Alternatively, the correction can be done by an external value (e.g. via connected pyrometer) by choosing the
process interface PIF in (please also see 2.5).
There are several Fitting modes to adjust the thermal image:
The option Consider flagis decreasing the influence of the camera’s correction (high temperature steps)
onto the display of the reference temperature. It is recommended to activate this option.
optris PIX Connect – E2018-03-A
34
2.4.6. Changing the optics (only PI)
Using the menu Tools, Configuration and Device the Optics
depending on the camera configuration must be chosen. As a
standard the camera can be delivered with different type of
lenses. If the camera is ordered with several additional lenses
the currently used optics must be chosen in this menu (only PI).
With the help of the menu point Radial Distortion Correction, the camera image can be corrected in such a
way that the image distortion is compensated by the optics (barrel distortion). It can be selected between Off,
Normal and Wide.
2.4.7. Changing the temperature range
Using the menu Tools, Configuration and Device the most
suitable Temperature range for the process can be set. The
imager features different temperature ranges depending on
the device.
Alternatively, the temperature range can also be changed via the
status bar in the PIX Connect software window. To do this, make a
right-click on the temperature range.
A useful function is the adjustable, extended temperature range under Extended.
The temperature range 150 °C ... 900 °C can be extended from 20 °C. The
accuracy between 20 °C ... 150 °C is no longer exact. This function is used to
optris PIX Connect – E2018-03-A
35
display an IR image with or without temperatures between 20 °C ... 150 °C. This is especially useful if an IR

The extended temperature range is usable for all PI 160 /2xx /4xx /640 cameras, calibrated from
March 2017 onwards and for all Xi cameras.
image is to be displayed between the hot processes.
With High resolution temperatures (if available), the temperature display has two decimal places instead
of one decimal place. This function is only available for certain camera models.
2.4.8. Video formats (Device framerate)
The cameras have different framerates. To change this, go to Tools, Configuration and
Device in the menu.
Alternatively, the device framerate can also be
changed via the status bar in the PIX Connect
software window. To do this, click on the device
framerate with the right mouse button.
With the camera PI 1M/ 05M, the user has the possibility to choose the
1 kHz mode. If this is selected, a window appears with the information
that the clipped format will be changed and the position of the section
itself can be set.

2.5. Imager interfaces for PI and Xi 400 camera
2.5.1. General
The imager is equipped with a process interface (cable with integrated electronics and terminal block), which
can be programmed via the software as an Analog Input (AI) and Digital Input (DI) in order to control the
camera or as an Analog Output (AO) in order to control the process. The signal level is always 0-10 V. The
process interface can be activated choosing the following options:
Analog Input (AI): Emissivity, Ambient temperature, Reference temperature, Uncommitted value, Flag
Analog Output (AO): Main measure area, Measure area, Internal temperature, Flag Status, Alarm, Frame
sync, Fail-safe, External Communication
Digital Input (DI): Flag Control, Triggered Snapshots, Triggered Recording, Triggered Linescanner,
Triggered event grabber, Reset Peak-/Valley-Hold
Configuration Process Interface (PIF)
Frame synchronization: In this function, a needle pulse is output for synchronization with fast processes at
the beginning of each frame.
optris PIX Connect – E2018-03-A

2.5.2. Process interface (PIF)
If you configure an analog value an
additional window will show up if you press
the Setup button. In this window you can
scale the in- or output:
Using Tools, Configuration and Device PIF menu you can configure a PIF which is connected to the
camera. The number of in- and outputs can vary depending on the connected PIF (Standard-PIF or Industrial
PIF). An available in- or output will be marked with a green checkmark (). A not available in- or output will
be marked with a red x. With Set number of ports like connected device, only the available inputs/outputs
are displayed.
optris PIX Connect – E2018-03-A

The recording frame rate corresponds to the device frame rate of the camera.
Skipping
It skips so many pictures that the set display frame rate results.
Average
The pixels are averaged out of a sequence of images. This weakens the detector noise.
Minimum
From a sequence of image, the smallest value is displayed for each pixel.
Maximum
From a sequence of image, the highest value is displayed for each pixel.
Ext.
Averaging
Is a combination of average and skipping and is used at very low frame rates. The
averaging time indicates how many percent of the set frame time should be averaged.
In the remaining time, the frames are skipped (e.g., if the frame rate is 1 Hz and the
averaging time is 100 ms, then 100 ms is averaged and 900 ms is skipped).
3.4.1. Setting the recording frame rate
The camera’s maximum frame rate depends on the camera model you’re
using and can be reduced. Using Tools, Configuration, Recording and
Recording framerate the speed of the data capturing can be set. Typically,
the specification is in Hertz (Hz, images per second).
The software gets the full frame rate from camera. That is why you need to define what to do with the images
which are left if choosing a reduced frame rate. There are several alternatives to set in the Mode option:

4.1.2. Calculated Objects
Off
The operation is off.
Difference
Calculates the difference temperature of
two selected measuring areas (Operand 1
and Operand 2).
Absolute difference
The result is a positive number which
results from the formation of the difference
between two selected measuring areas
(Operand 1 and Operand 2).
Average
In this mode an arithmetic algorithm will be performed to smoothen the signal.
The Averaging time [sec] is the time constant. This function can be combined
with all other post processing functions. If activated (Smart averaging [°C]), a
dynamic average adaptation at high signal edges is active.
Peak Hold
This function keeps the respective signal maximum. When the temperature
drops, the algorithm keeps the signal level for the set Hold time [sec]. After the
hold time the signal will drop down to the second highest value or will descend
by 1/8 of the difference between the previous peak and the minimum value
Calculated objects allow you to select various operations that offer a
signal processing. The name for the created object can be changed in
the field Name. Furthermore, in the field Show in digital display group, you can decide whether the object is to be displayed in the
digital display group or not. Under Operation, you can choose between
the following operations:

during the hold time. This value will be held again for the specified time. After
this the signal will drop down with slow time constant and will follow the current
object temperature. Therefore, if periodic events will be measured (bottles on a
conveyor e.g.) this peak hold function avoids a drop down of the signal to the
conveyor temperature in-between 2 events.
Valley Hold
With this function the respective signal minimum is held. If the signal ascends
the algorithm maintains the previous signal valley for the specified Hold time [sec]. The definition of the algorithm is according to the peak hold algorithm
(inverted).
Adv. Peak Hold
This algorithm searches for local maximum values. Peak values which are lower
than their predecessors will only be taken over if the temperature has fallen
below the Threshold [°C] value beforehand. If Hysteresis [°C] is activated a
peak in addition must decrease by the value of the hysteresis before the
algorithm takes it as a new peak value.
Adv. Valley Hold
This function behaves inverted to the extended maximum search. This algorithm
searches for local minimum values. Minimum values which are higher than their
predecessors will only be taken over if the temperature has exceeded the
Threshold [°C] value beforehand. If Hysteresis [°C] is activated a minima in
addition must increase by the value of the hysteresis before the algorithm takes
it as a new minimum value.

value is not taking values below or above the set limits into account.
For hot/cold spots localization determines that all pixels with the defined values are excluded from search.
For </> temperature ranging means that all pixels with the respective temperature do not influence e.g. the
automatic scaling of temperature-time-diagram.

4.8. Alarms
Note
The background color of the window for the digital display of the
main measuring field also changes when the alarm value is below
or exceeded, in light blue or blue (low alarm) or orange or red (high
alarm).
In the Tools, Configuration and Alarms menu you
can define an alarm and pre-alarm for each
configured measure area as well as for the
predefined values (please also see 2.2.4). Prealarms can be useful as an advance warning.
The alarm values can be displayed as figures in the
digital display or in a graphical way as a bar. For the
latter you need to activate the option GraphBar. Regarding the bar you can
define via Display ranges the Min. and Max. value (temperature borders).
With Alarms the Low and High thresholds can be set which finally defines
the displayed color.
If the high alarm value is reached or exceeded the color of bar changes to
red, for pre-alarm orange. If the measured temperature reaches or goes
below the lower alarm value the color of bar changes to blue, for pre-alarm
light blue. Temperatures in between the defined thresholds are displayed
green.

optris PIX Connect – E2018-03-A
If a temperature value shall be used as an pre-alarm, you need to tag the Pre-alarms option.
Note
If activating the Alarm Appl., a red alarm button on the toolbar appears. You can
deactivate the visual and acoustic alarm by clicking on the alarm button. The alarm will
stay deactivate until the alarm value is reached again.
The alarm can also be put out via the Process Interface (PIF) using the Alarm to PIF option.
In the Alarm configuration window you can set an Audible alarm.
In the Interval [sec] input box you can specify the time
interval the sound appears. Via the Path to sound file
you can Browse an individual *.wav file
The acoustic alarm signalization can be repeated in
defined intervals setting the Interval [sec].
Using the option Recording on alarm you can specify a
Delay [sec]. The recording starts after the delay time is
over. In the Duration [sec] box the recording time of the
video sequence can be set.
optris PIX Connect – E2018-03-A
83
Furthermore, a recording can be stopped via Abort recording if alarm condition drops out. If this option is
not chosen the recording will be finished based on the time in the duration box.
With the Snapshot on alarm option you can set a Delay [sec] time before an
alarm will trigger the storage of an image.
4.9. 3D display of thermal image
Thermal images can be displayed in real time as
3 dimensional images. The 3D Chart is displayed in a
separate window. To add the software window please
use the menu item View, Windows and 3D Chart or
the Icon on the toolbar
optris PIX Connect – E2018-03-A
84
4.10. Event grabber
Batch processes are easy to handle thanks to the event grabber. In the case of fast-paced recurring
processes, a snapshot is created when an alarm condition occurs, in order to be able to analyze critical
areas.
The settings can be found under the menu Tools, Configuration and Event grabber.
Under Trigger mode you can select between Self-triggered (on alarm of a measure area) and External triggered (on PIF).
In the case of Self-triggered (on alarm of a measure area), the event
is triggered by the set application alarm. At first the Triggering measure area has to be selected at which the set alarm condition is to
be triggered.
At External triggered (on PIF), the event is
triggered by the process interface (PIF). For this, a
Trigger input must first be selected. The available
inputs depend on the PIF which is used.
On trigger hold, the following items can be selected:
3D Chart: The 3D diagram is held in case of an alarm condition.
Temperature Time Diagram: The Temperature Time Diagram is
held in case of an alarm condition.
Temperature Profile: The Temperature Profiles are held in case of
optris PIX Connect – E2018-03-A
85
an alarm condition.
Histogram: The Histogram is held in case of an alarm condition.
Under Extended settings, a Holdoff time can be entered. A new
alarm condition is not taken into account during this set time.
If the checkmark is enabled by Allow event grabbing (and alarm)
while playing, the event grabber is considered when playing a Ravi.
Create snapshot on event will create a snapshot after every event
which will appear in the snapshot history and in the event grabber
(frozen image) window.
The triggered snapshot for the event grabber can be found under menu View, Windows and Event grabber (frozen Image).
Measurement areas can be created and arranged in the live IR image as well as in the event grabber (frozen
image). If you want to add an measurement area in the event grabber (frozen image), this must be set under
the Configuration menu and Measure areas. Under Measure area, the check
mark Use in event grabber must be selected.
As a template for the event grabber, you can use the sample layout Event grabber.

5. Xi camera
Note
Imager interfaces for Xi 400, please see chapter 2.5
5.1. Focus setting
The special feature of the Xi camera is the motorized focus
adjustment. This can be found under menu View, Windows
and Distance. Here you can change the position of the focus by
moving the gray slider. The black slider marks the current
position of the engine. With the arrow keys you can also change
the position in different stages. An adjustment to the left leads to the focus setting "near" and an adjustment
to the right to the focus setting "infinite".
5.2. Imager interfaces for Xi 80
5.2.1. General
The Xi 80 has a direct analog input (AI) / digital input (DI) for camera control and a direct analog output (AO)
for process control. These can be connected to the supplied terminal block. In addition, there is an RS485
interface. When using the RS485 interface, the direct outputs and inputs are not available. The signal level is
0 10 V for AI and 0/4-20 mA for AO. The interfaces can be set up by the software with the following
functionality:
Analog Input (AI): Emissivity, Ambient temperature, Reference temperature, Uncommitted value, Flag
Analog Output (AO): Main measure area, Measure area, Internal temperature, Flag Status, Alarm, Frame
sync, Fail-safe, External Communication
Configuration Process Interface (PIF)
Frame synchronization: In this function, a needle pulse is output for synchronization with fast processes at
the beginning of each frame.
5.2.2. Process interface (PIF)
Using Tools, Configuration and Device PIF menu you can configure a PIF which is connected to the
camera. The number of in- and outputs can vary depending on the connected PIF type (internal PIF or
stackable PIF). An available in- or output will be marked with a green checkmark (). A not available in- or
output will be marked with a red x. With Set number of ports like connected device, only the available
inputs/outputs are displayed.
optris PIX Connect – E2018-03-A
89
If you configure an analog value an
additional window will show up if you press
the Setup button. In this window you can
scale the in- or output:
Note
You can use the analog inputs, outputs and the digital input of the PIF simultaneously.
On the analog inputs you can select each function only once (exception: Uncommitted value).
On the analog outputs also each function can only be selected once (exception: Measurement area; Alarm).
optris PIX Connect – E2018-03-A
90
The settings for the stackable PIF are similar to those for the internal PIF. Under PIF type, Stackable PIF
must first be selected. Furthermore, the number of PIFs used must be specified under Devices. The device
number must be identical to the RS485 address set on the device. Now the existing inputs and outputs can
be assigned with corresponding functions.
The numbering of the individual inputs and outputs is structured as follows: The first number refers to the
device and the second to the port (for example AI2.3: Analog input from PIF No. 2 and Port No. 3).
optris PIX Connect – E2018-03-A
91
If you activate the function Alarm on an analog output you need to assign also in the Alarms tab the desired
measurement area to the desired PIF output.
The industrial PIF has a maximum of three analog outputs. To use more outputs, you can cascade up to
three PIFs, allowing you to use up to 9 analog or alarm outputs in total.
For more information on the settings for alarms, see section 4.8 Alarms.

The failsafe function can be activated in the tab Device (PIF) under FS.
The industrial PIF has a separate failsafe relay.
Alternatively you can activate this function also on the analog outputs.
The checkbox Stop fail-safe pulse on alarm must be activated, if the
analog output should be used in addition as an alarm output for a
temperature alarm. In case of an alarm the alternating fail-safe pulse
signal will stop and the set voltage level will be given out as constant
value (stackable PIF only).

5.3. IP settings Xi 80
The Xi 80 has a direct Ethernet interface (see Xi manual). To make the
appropriate address settings, go to Tools, Extended and TCP/IP Settings.
The address for the device is assigned under Device address. This must
have a different address to the other participant (Send to address).
5.4. Autonomous operation Xi 80
A special feature of the Xi 80 is the autonomous operation. There is no need for a permanent connection to
the PIX Connect software. Only a few settings must be set in advance in the software.
Proceed as described in chapter 5.2.2. Select an output and press
Setup. Here you have to put the check in using autonomously by
device.
A @ sign will appear next to the output used in the
configuration menu Device (PIF). Whenever this
sign is visible, the function can run in autonomous
operation.

6. Visual Camera (only PI200/230)
6.1. Enabling the visual camera
The PI200/230 thermal imager features a visual camera. With the help of BISPECTRAL technology, the visual image (VIS) can be combined with a
thermal image (IR). Both can be finally captured time synchronously. The
visual camera can be enabled in the Tools, Configuration and General
menu under VIS camera via the option Use (if available).
The menu Tools, Configuration and Device displays the Video formatsdepending on the current imager’s configuration.
The thermal image (160 x 120 pixels) will be shown with 96 images per
second (96 Hz), the visual image (640 x 480 pixels) with 32 Hz. In the
second mode, the thermal image is displayed at 160 x 120 pixels with a
speed of 128 Hz and the visual image with a resolution of 596 x 447 pixels with 32 Hz.
6.2. Monitoring mode
The monitoring mode is used to have an easy orientation at
the point of measurement. In this mode the visual image is
displayed in a separate window.
To add the separate software window please use the menu
item View, Windows and Video from VIS camera or the
Icon on the toolbar.
optris PIX Connect – E2018-03-A

Note
The rectangle within the visual image shows the area covered by the thermal image. In order to
cover a big area the wide-angle lens is used, to cover a smaller area the telephoto lens.
In the View, Image Information and IR rectangle menu it is possible to hide the displayed
rectangle.
Note
The area covered by the thermal image within the visual image is limited by a rectangle. In order to
hide the frame of the rectangle, use the View, Image Information and IR rectangle menu.
6.3. Cross-fading mode
6.3.1. General
The cross-fading mode is used in order to highlight critical temperatures at the point
of measurement. In this mode the thermal image is faded into the visual image.
The cross-fading mode can be enabled in the Tools, Configuration and General menu via the option
IR/VIS fusion. Alternatively, you can use the menu item View and IR/VIS fusion or the Icon on the toolbar.
The function Distance is used in the cross-fading mode to perform the
parallax correction between IR and VIS image.

7.1. General information
The PIX Connect software comes with a line scanner function. The
line scanner mode is generally used for continuous processes with
moving objects under test, such as measurement of rotary kilns or
measurement of great lots at conveyor belts (batch process).
Overview of the advantages:
Simple monitoring of process with limited optical access Indirect visualization of heat distribution within ovens via
camera installation at the oven exit
Extension of number of pixel through the use of the picture
diagonal (e.g. PI 160)
Very fast data recording of unlimited lines which-in
turn can produce thermal images of any resolution
Huge FOV as a line for detailed process analysis such as
at wide conveyor belts (e.g. PI 160 with an 72° optic)
