Operating instructions CellaCast PX 8x
8 Focussing
If the pyrometer is mounted in a cooling or protective housing, remove the pyrome-
ter from the protective fitting� For easier focusing, hold the pyrometer parallel to the
cooling or protective fitting�
Pyrometer with through-lens sighting
When aiming the pyrometer with through-the-lens sighting to a target, both the
targeted object and the target marker (distinctly marked circled or rectangle spot in
the viewfinder) must appear in sharp focus simultaneously�
Pyromter with camera
The models PX xx AF xx /C features an integrated camera� When aiming the
pyrometer focus the sensing head until the video images is sharp�
Pyrometer with laser sighting
The pyrometer models PX xx AF xx /L feature a laser spot light which can be
activated to facilitate instrument alignment to the target spot� To activate the laser,
press the MODE button on the rear panel for 2 seconds� Alternatively, the laser
can be switched on with the IO-Link interface�
To focus, rotate the optics until the pilot light is projected as a sharp, round light
spot on the object to be measured�
Pyrometer with fibre optic
The pyrometers have a laser that can be activated to align the sensing head to the
target spot� To activate the laser, press the MODE button in the real panel for 2
seconds� Alternatively, the laser can be switched on via the IO-Link interface
For focal adjustment loosen the shown socket screw (hexagon socket screw DIN
916) with a wrench (DIN 911) and shift the internal body of the tube towards the
lens tube� Due to the O-ring sealing between the internal body of the tube and the
lens tube the focal adjustment must be carried out very slowly so that the air pres-
sure in the space between lens and internal body of the tube can be equalised�
