6.2.2 Optical head type II, focusable
For adjustment of the correct distance, untighten the fixing
nut and vary the length of the optical head by turning the lens
tube. In the correctly focused distance the laser has its small-
est spot size (sharpest image). After adjustment tighten the
fixing nut.

Laser targeting light
For easy alignment to the measuring object the pyrometers are equipped with a laser
targeting light. The laser marks the center of the measuring spot and corresponds to the
spot size. With the IGAR 12-LO the measurement is not effected by the laser targeting
light. As the laser targeting light influences the measurement of the ISR 12-LO the last
measured value is hold in the analog output. The display shows during this time the intensity of the relative
signal (see also 10.8 Measurement color bar). In mono mode the display shows a blinking “8000”. The
laser targeting light is switched off automatically after approx. 2 min or after a further push of the PL key.
Note: The smallest diameter of the laser spot indicates the correctly focused meas-
uring distance. The diameter corresponds to the spot size!
The laser targeting light can be switched on and off either by pressing the button at the housing (see also
section 8.1 Key panel operation) or by using an external contact (see 4.1 Pin assignment for the connec-
tor on the bottom side of the pyrometer) or via PC and the software InfraWin (see section 10, Settings
via interface and software). After two minutes the laser targeting light is switched off automatically.
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.
Note: The laser warning signs on the pyrometer should be easily viewable at all
times, even after it has been installed.
Note: To prevent the damage of the laser, the pilot light switches off automatically if
the internal temperature of the device exceeds approx. 55°C (it can switched-
on again, if the internal temperature is lower than 55°C)!
8 Instrument settings
Certain settings have to be done for use of the entire specifications of the pyrometer. The most settings can
be done at the instrument directly, a few (e.g. setting of contamination level) only via software InfraWin (see
section 10, Settings via interface and software).
After removing the cover of the housing, the setting keys of the pyrometer are accessible.
Note: Please make sure that the pyrometer is not contaminated while open.
