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. 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
measuring 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
3.6
Key panel operation) or by using an external contact (see
3.2 Pin assignment
for the connector on the bottom side of the pyrometer) or via PC and the
software InfraWin. 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 be switched on
again, if the internal temperature is lower than 55 °C)!
