2.1 Appropriate use

The IMPAC ISR 6 pyrometer is a stationary, digital pyrometer for non-contact temperature
measurement metals, ceramics, graphite, etc. in ranges between 600 and 3000 °C.

The pyrometer measures in 2-color mode (ratio principle) in which two adjacent wavelengths
are used to calculate the temperature. This technique offers the following advantages when
compared with standard one-color pyrometers:

· The temperature measurement is independent of the emissivity of the object in wide
ranges.

· The measuring object can be smaller than the spot size.

· Measurements are unaffected by dust and other “grey” contaminants in the field of

view or by dirty viewing windows.

The pyrometer can also be switched to 1-color mode and used like a conventional pyrometer.

2.2 Scope of delivery

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.

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.

M orange

don’t connect to the
switchboard

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
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 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).

dropdown

clear

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. 3 826 720).

ISR 6 Advanced Manual Controls and Installation · 16

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).

Connection Schematic for Analyzing Devices

ISR 6 Advanced Manual Controls and Installation · 17

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.

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.

Examples of Spot Sizes in Relation to Measuring Distance

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 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 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 e 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 = e1 / e2) 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

ISR 6 Advanced Manual Settings / parameter descriptions · 21

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 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 = e1 / e2) 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,
e1 / e2= 1 and stays constant regardless of the target temperature. When a target deviates from
this, that is when e1 / e2 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 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 20%.

Note: Transmittance t Settings: 5% to 100% in steps of 1/1000 (1-color mode)

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.

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 t90 : min, 0.01 s; 0.05 s; 0.25 s; 1 s; 3 s; 10 s

4.6 Clear Peak Memory (t

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.

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:

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.

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 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.

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 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.

EXTERN

ISR 6 Advanced Manual Settings / parameter descriptions · 24

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.

AUTO 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.

HOLD 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.

ISR 6 Advanced Manual Settings / parameter descriptions · 25

Note: Settings for Minimum Intensity Switch-Off Level: 2% to 50%

Ratio pyrometers are able to measure temperatures correctly even with very low signals. If the
signal is too low for a correct measurement, the pyrometer interrupts the measurement and
displays 1 °C below of beginning of the temperature range.

Although the factory default is set to 10%, switch-off limit can be adjusted between 2 and 50%,
depending on the application.

Note: The smaller the value, the higher the chance that daylight or reflections will
affect a correct temperature measurement.

4.11 Operating Modes

Ratio (2-color) mode is the factory default operating mode for the ISR 6 pyrometer. However,
the device can be set to mono (1-color) mode using the InfraWin software or by using the UPP
Data Format commands.

With 1-color mode, the device adjustments are simplified by
sending the emissivity corrected one channel temperature to the
analog output.

For a correct measurement in the 1-color mode, it is necessary to
adjust the emissivity using the InfraWin software or by using the
UPP Data Format commands. This emissivity is the relationship
between the emission of a real object and the emission of a
blackbody radiation source (this is an object which absorbs all
incoming rays and has an emissivity of 100%) at the same
temperature.

4.12 Sub Range

You have the opportunity to choose a sub range (minimum span 50 °C) within the basic
measuring range of the pyrometer. This sub range corresponds to the analog output.

Example: Range 700…1800 °C, Sub Range 925…975 °C.

The sub range setting also affects the maximum value storage when the Clear Peak Memory
t

is set to AUTO. For more information on the t

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

ISR 6 Advanced Manual Settings / parameter descriptions · 26

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).

4.14 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.

further temperature measurement.

5.5 Relative Signal

The relative signal bar graph provides and indication of the signal strength.

InfraWin Software Relative Signal Indicator

In the above image, the relative signal bar indicates a signal intensity of 25.2%. This can be
caused by the object’s emissivity, contamination of the optics or viewing window, dust in the
field of view, or a small measuring object.

Normally, this bar graph is used to monitor if the signal level due to contamination of optics or
window decreases over time. It shows the measured intensity compared to the intensity a
blackbody radiation source would have at the determined ratio temperature of the pyrometer.

The shown relative signal depends on the entered emissivity slope K (a wrong adjustment results
in relative signals above 100%).

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 signal becomes too low. When this happens, the built-in indicator of the
pyrometer starts blinking, but will continue the measurement.

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 the function external
clearing of maximum value storage or external hold, when one of them is activated.

The switch-off level is a function used to avoid measuring errors caused by too low signals.
Ratio pyrometers are able to measure temperatures correctly even with very low signals. For
example, through a dirty viewing window, or if dust exists in the field of view, or if the spot is
not filled by the measuring object.

If the signal is too low for a correct measurement, the pyrometer interrupts the measurement
and displays 1° below the beginning of the temperature range. Although the factory default is
set at 10%, the switch-off limit can be adjusted between 2% and 50%, depending on the
application.

5.7 Emissivity Slope K: AutoFind

InfraWin also offers an input field K for the emissivity slope. If the emissivity is changed, the
temperature change connected with this can be directly affected.

If the true temperature of the measured object is known, you can calculate the emissivity slope
of the measured object using the K: AutoFind function:

A measured temperature is displayed with
the current set emissivity slope. In this
example, the emissivity slope is set at 1.000
and the resulting temperature reading is

845.2 °C.

If you press the K: Autofind button, a
window will open which allows you to
enter the true temperature.

In this example, we have entered a
temperature of 870 °C.

Once you enter the temperature value, you
can press the OK button to set the
temperature value and close the
temperature window.

ISR 6 Advanced Manual Software InfraWin · 32

Once the temperature entry has been entered
and confirmed with OK, InfraWin will then
calculate the emissivity slope. The new
emissivity slope will immediately appear along
with the new temperature, which can be used
for further temperature measurement.

5.8 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 699 and 713 °C. The final temperature (at the end of the reading) is

699.0 °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.

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.

5.9 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 5.9 PC sampling rates). As

ISR 6 Advanced Manual Software InfraWin · 33

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.

5.10 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).

5.11 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.

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.

5.12 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.

5.13 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.

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.

ISR 6 Advanced Manual Data format UPPÒ· 37

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.

Information on this topic can be found in Section 3.3 Optics and Section 4.14 Focused
Distance.

· Obscured window: Refer to Cleaning ISR 6 Window, Section 6.1.1.

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.
