ISR 6 Advanced Manual Controls and Installation · 18
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.
