6 Optics
The pyrometer is equipped ex works with a 10:1 optics. The lens is focusing to a distance of 400 mm, i.e. in
this distance the lens achieves its smallest spot size in relation to the measuring distance. The spot size will
change in any other distance (shorter or longer) corresponding to the following drawing. Please notice that
the measuring object must be as least as big as the spot size.
6.1
Aligning to the measuring object
For exact measurement of the object temperature the pyrometer must be aligned correctly onto the object.
The instruments are not equipped with a sighting so that the aligning must be done thermally. When measur-
ing a hot object in front of a cooler background, it usually suffices to align the pyrometer to achieve the
highest temperature reading.
7 Parameter descriptions / settings
The pyrometer is equipped with a wide range of settings for optimal adaptation to the required measuring
condition and to measure the temperature correct.
All settings can be read and set only in the pyrometer parameters
window of the software InfraWin (via the optional USB adapter), at
the instrument no setting is possible (detailed description of the
software see section 8, 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.
