INFO to the spot size: The size of the laser point does not match to the spot size, spot sizes
are given in the spot size tables (see 5.6 ).
CAUTION, Laser Radiation, Laser Class 2:

Never look into the direct or reflected laser beam.

Do not point the laser to anyone.

If laser radiation hits the eye, the eyes must be intentionally closed and the head immedi-
ately moved out of the beam.
Turn on / off: Via the targeting light button on rear panel or via software
SensorTools (see 7.2.2 Control window ).
(the targeting light will automatically switched off after 3 minutes if it is not
switched off manually. Adjustable via software under
7.2.3 Device Set-
tings

Laser targeting light settings ).
INFO: The laser targeting light is turned off at a device tem-
perature above 65°C (M3 devices) or 60°C (H3 devices)
If the targeting light does not turn on, probably the device's inter-
nal temperature is too high. In this case, the place of installation
of the pyrometer should be checked (excessive heat radiated
from the measuring object). If the temperature falls below the
switch-off value, the laser will work again.
5.4.2 Alignment with the Through Lens Sighting / View Finder
The view finder provides upright imagery so that the target under
measurement can be viewed visually. A target circle shows the
measuring spot when the target is in focus.
Devices with temperature range above 1400°C are equipped with a
continuously adjustable eye protection filter in the eyepiece to reduce
glare at high measurement temperatures. Rotating the eyepiece will
change the brightness.
INFO: The size of the target circle does not match to the spot
size, spot sizes are given in the spot size tables (see 5.6 ).
CAUTION, Danger of eye damage at measuring temperatures above 1400°C!
To protect the eyes at high measuring temperatures, first, before alignment, the eyepiece
must be adjusted to the darkest position, a safe method is the adjustment by looking at a
replacement light source, e.g. a lamp.
5.4.3 Alignment with the Camera Module (only M3)
Pyrometers with a color camera module provide
a composite video output that can be connected
to a TV or monitor or PC via converter. The py-
rometer is focused and aligned via a target cir-
cle on the TV screen.
About the field of view of approximately 3.6% x
2.7% of the measured distance also the meas-
urement events can be observed. About the PC
software, image overlays and camera settings can be configured (see under
7.2.2 Control window

camera settings ).
INFO about the target circle size: The size of the target circle does not match to the spot size,
spot sizes are given in the spot size tables (see 5.6 ).
