of emitted signal (providing the object’s temperature) and unwanted reflected (and for transparent
objects: transmitted) signals from objects (such as walls) in the environment.
For example, under standard (lab) conditions, the walls have nearly the same temperature as the
air, which is surrounding the pyrometer. In this case, the ambient compensation setting is set to
“auto.” The pyrometer senses the environment as ambient air temperature and can compensate for
this influence.
The measurement might be falsified (probably too high) if you place the measured object in an area
with a higher wall temperature than the air temperature around the pyrometer. InfraWin allows
for some pyrometer models to switch to "manual" compensation. In this case, you will need to
enter the average temperature of the walls surrounding the measurement object and perform the
compensation with the value you entered.
Attention: This method only improves the results if the ambient temperature surrounding
the measured object is always constant and the emissivity is well known.
3.2.17 Basic Range
The Basic Range automatically displays the total range of the pyrometer. The values for the Basic
Range cannot be changed.
3.2.18 Sub Range
You have the opportunity to choose a sub range within the basic measuring range of the
pyrometer. Example: Temperature Range 700...1800 °C, Sub range 925...975 °C.
This sub range corresponds to the analog output. Reduction of the temperature range increases the
accuracy of the analog output.
In addition to setting the sub range, it is also possible to fulfill the requirements of the “auto” clear
mode of the maximum value storage.
3.2.19 Laser
If the pyrometer is equipped with a laser targeting light, the laser icon should be visible. You can
activate and deactivate the laser targeting light through the InfraWin software by clicking on the
laser targeting light icon.
The laser targeting light can also be activated and deactivated by pressing the laser targeting
button located on the back of the pyrometer.
After approximately two minutes, the laser targeting light is switched off automatically.
Attention: 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. Never look directly into the
laser beam. The beam and spot can be watched safely from the side. Also make sure that
the beam will not be reflected into others’ eyes by mirrors or shiny surface.
3.2.20 1-Channel Temp / Ratio Temp
The standard operation mode for 2-color pyrometers is Ratio temp. If 1-channel temp is selected,
the pyrometer can be used like a conventional single- channel pyrometer.
3.2.21 LED targeting light
When the pyrometer is supplied with power, the LED targeting light is automatically active.
InfraWin allows you to change the power-on status of the LED to inactive. Independent of the LED
setting, the targeting light can be switched on or off at this point using the targeting icon. ).
