3Safety
This section offers an overview about important safety aspects. Additionally in the several sections
there are concrete safety aspects to avert danger. These aspects are indicated with symbols.
Labels and markings at the instrument have to be observed and kept in a permanent readable
condition.
3.1 General
Each person working with the pyrometer must have read and understood the user manual before
operation. Also this has to be done if the person has already used similar instruments or was
already trained by the manufacturer.
The pyrometer has only to be used for the purpose described in the manual. It is recommended to
use only accessories offered by the manufacturer.
3.2 Laser targeting light
For easy alignment to the measuring object the pyrometers can be equipped with a laser targeting
light. This 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.
Warning: 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 that emits radiation.
Safety regulations:
•Never look directly into the laser beam. The beam and spot can be watched safely from side.
•Make sure that the beam will not be reflected into eyes of people by mirrors or shiny surfaces.

4Commissioning
4.1 Battery insertion
For operating the IGA 15 plus a 9 V
battery or 9 V rechargeable battery
is necessary. For insertion of the
battery remove the locking screw
and the battery case cover.
Now the instrument is ready to use.
4.2 Switch on
The instrument’s push button has
two trigger points.
First trigger point :
The instrument is switched on if the button is pushed to the first trigger point. The measurement
starts after a short self test of approximately 1 second. After releasing the push button the last
measured value will be displayed for 10 seconds (HOLD function) and the sign “HOLD” is shown
on the display. After these 10 seconds the instrument is switched off automatically.
The display indicates “7777” if the measured temperature is below 250°C, it indicates “8888”
above 1800°C.
Second trigger point:
The second trigger point activates the data logger and stores the actual temperature reading. It
can be adjusted if only the actual temperature value is stored or if a continuous storing should be
done as long as the push button is hold on the second trigger point (setting of time interval see
6.10).
The data logger can store up to 750 temperature values. Should the pyrometer be switched to
single value data logging, the data logging is confirmed by a beep and in the display the used
number of the stored value is indicated for a short time (e.g. for the first stored value STO#01 is
shown).
Locking lever: The push button can be locked in the second trigger point position with the locking
lever by pushing the lever upwards. This activates the continuous measuring mode. Pressing the
trigger once again releases the locking and switches off the continuous measuring mode.
4.3 Sighting
For exact aiming to the object the pyrometer is equipped with a laser target-
ing light. The laser shows a red flashing circle at the position of the measur-
ing spot on the object. The size of the circle varies depending on the distance
and has approximately the size of the measuring spot.
If the instrument is in operation, i.e. push button is in first or second trigger point, the laser
targeting light function can be activated or deactivated by pressing the laser key. If this
function is activated the laser targeting light is automatically switched on as long as the
trigger button is pushed.

4.4 Spot size
The size of the measuring spot of the pyrometer and with that the minimum size of the measuring
object is dependent on the distance. The smallest spot size of 4 mm in diameter is achieved only
in a measuring distance of 800 mm. The spot is decreasing if the distance to the measuring object
is decreasing of increasing from 800 mm.
A spot size table is printed on the right side of the pyrometer corresponding to the below shown
spot size diagram.
Smallest objects with only 1.25 mm diameter can be measured with the additional close-up lens
(optional accessory).
Note: The pyrometer can measure objects at any distance but the object has
to be bigger or at least as big as the spot size of the pyrometer in the
measuring distance.
For longer measuring distances than 800 mm the size of measuring spot can
be calculated approximately with the following equation:
M = (0.019 x a) - 11 M = spot size in mm
a = measuring distance in mm
With close-up lens (optional):
If using the close-up lens, the emissivity setting of the instrument (EMI) has to
be corrected with the following factor (emissivity see 6.1):
EMI = 0.92 x EMIobject
For longer measuring distances than 250 mm with the close-up lens the size
of measuring spot can be calculated approximately with the following equa-
tion:
M = (0.05 x a) - 11 M = spot size in mm
a = measuring distance in mm

6Parameter description / adjustments
6.1 EMI (emissivity ε)
For a correct measurement it is necessary to adjust the emissivity. This emissivity is the relation-
ship between the emission of a real object and the emission of a black body radiation source (this
is an object which absorbs all incoming rays and has an emissivity of 100%) at the same tempera-
ture. Different materials have different emissivities ranging between 0% and 100% (settings at the
pyrometer between 10 and 100%). Additionally the emissivity is depending on the surface condi-
tion of the material, the spectral range of the pyrometer and the measuring temperature. The
emissivity setting of the pyrometer has to be adjusted accordingly. Typical emissivity values of
various common materials for the spectral range of the IGA 15 plus are listed below. The tolerance
of the emissivity values for each material is mainly dependent on the surface conditions. Rough
surfaces have higher emissivities.
Measuring object EMI (1.45...1.8 µm) Measuring object EMI (1.45...1.8 µm)
„Black body furnace“ 100% Zinc 45 to 55%
Steel heavily scaled 85 to 90% Nickel 15 to 20%
Steel rolling skin 80 to 88% Gold, Silver, bright 2%
Steel, molten 20 to 25% Porcelain glazed 60%
Slag 80 to 85% Porcelain rough 80 to 90%
Aluminum, bright 10% Graphite 80 to 90%
Chromium, bright 25 to 30% Fireclay 45 to 60%
Brass oxidized 60 to 70% Stoneware, glazed 80 to 90%
Bronze, bright 3% Brick 80 to 90%
Copper, oxidized 70 to 85% Soot 95%
6.2 MAX (maximum value)
The MAX function shows the highest reading taken during a measurement.
This feature is particularly useful for applications with fluctuating object temperatures or for the
measurement of moving objects which are not constantly in the measuring beam of the pyrometer.
With every new measurement the maximum value storage is cleared automatically, i.e. pushing
the trigger again.
Note: The response time of the pyrometer and with that the maximum value
storage function is faster than the update of the display.
6.3 MIN (minimum value)
The MIN function shows the lowest reading taken during a measurement.
Note: The response time of the pyrometer and with that the minimum value
storage function is faster than the update of the display.
6.4 AVG (average function)
The average function always shows the average of the readings of the last 4 seconds.

IMPAC pyrometer IGA 15 plus
11
6.5 DIF (difference temperature function)
If the DIF function is activated, a start temperature value is stored by pushing the trigger and the
temperature difference to the actual reading is indicated. That is why the indication an be positive
or negative.
6.6 HI (hi alarm)
The Hi alarm function is always active. Exceeding the adjusted alarm temperature (ex works
setting 1800°C) activates an intermittent acoustic signal (beep). Exceeding the end of the tem-
perature range (> 1800°C) the frequency will be higher.
6.7 CLR (clearing the stored measured values)
The clear function CLR deletes the complete data storage (data storage see 4.2). If the function is
selected, one of the arrow keys must be used to change the preselected value “no” into “yes”.
Pushing the PAR button within the next 6 seconds will clear the storage. The display shows “run”
until the storage is cleared.
6.8 STO#(determine the storage position)
The STO function determines the storage position number (between 1 and 750) from which the
pyrometer starts to store measured values in the following data recording. The position number
and the stored value of the last data logging will be displayed automatically. If a lower position
number will be selected, all storage positions above this number will be overwritten by new values.
If a higher position number will be selected, lower position numbers remain unused. Maximum 750
temperature values can be stored, then the sign “STO FULL” will be blinking in the display.
6.9 RCL#(recall measured values)
RCL shows the stored measured values. With the arrow keys the values can be displayed sequen-
tially.
6.10 INT (time interval for storage of measured values)
With the INT function it can be selected between single data storage or continuous data logging. In
position single data storage (INT = OFF) only one temperature reading is stored by pushing the
button into the second trigger point. In position continuous data logging (INT = 0.02 … 50) tem-
perature readings are stored continuously as long as the pushbutton is in the second trigger
position. The figures 0.02 … 50 are the time intervals in seconds between two stored values.
Maximum 750 temperature values can be stored, then the sign “STO FULL” will be blinking in the
display.
Position INT = PRT (print) is used only in connection with the optional software PortaWin. In this
position a single temperature reading is stored on a connected PC by pressing the push button
into the second trigger point, without using the built-in data logger of the pyrometer.
6.11 C / F (temperature display in °C or °F)
The temperature can be displayed in °C or °F.

IMPAC pyrometer IGA 15 plus

6.12 Time
The pyrometer is equipped with an integrated clock. Time and date are only used in combination
with the stored values and can only be read out via interface and software PortaWin. On the PC
they are shown additionally to the measured temperatures (see 8.2 software PortaWin).
The clock has its own power supply and is running even if the pyrometer battery is taken out.
Time setting: - pyrometer must be switched off
- press laser targeting light key and parameter key at the same time
- keep them hold and press the push button to switch the instrument on.
- time appears on the display
- the blinking part, hours or minutes can be set with the arrow keys
- switch from minutes to hours and back with the parameter key
- switch back to the measuring mode by pushing the trigger switch
The date can only be changed by PC via software PortaWin, not on the instrument.
7Interface
The pyrometer is equipped with a serial USB inter-
face.
Via serial interface the pyrometer can be connected
to a PC. This allows to read out the stored data and
analyze them graphically or in table form. Also the
instrument can be used in continuous mode in com-
bination with a PC and the data are displayed on the
monitor as an online diagram (for connecting cables
and software see 13,Reference numbers accesso-
ries).
7.1 USB cable
To connect the IGA 15 plus with a PC, a standard
cable USB-A to mini-USB (5-pole) is necessary
(reference numbers see 13, Reference numbers
accessories).
8Accessories

10 Transport, packaging, storage
The instrument can be damaged or destroyed if shipped incorrectly. To transport or store the
instrument, please use the original box or a box padded with sufficient shock-absorbing material.
For storage in humid areas or shipment overseas, the device should be placed in welded foil
(ideally along with silica gel) to protect it from humidity.
The pyrometer is designed for a storage temperature of -20 to 70°C with non-condensing condi-
tions. Other kind of storage can damage or malfunction the pyrometer.
11 Maintenance
The pyrometer does not have any parts which require regular service, only the lens has to be kept
clean. The lens can be cleaned with a soft cloth in combination with alcohol (do not use acid
solutions or dilution). It is also possible to use standard cleaning tissue for glasses or camera
lenses.
It is recommended to send the pyrometer every two years to LumaSense for recalibration.
