5.4.3 Alignment with the Camera Module
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
Control window
).
INFO:
The size of the target circle does not match to the spot size, spot sizes are given in the
INFO:
The camera module of M3 devices is turned off at a device temperature above 55°C.
If the camera module does not turn on, probably the device's internal temperature is too high. In
this case, the place of installation of the pyrometer should be checked (excessive heat radiated
from the measuring object). When temperature falls below 55°C the camera module is working
again.

Setting the Measuring / Focus Distance
The focal distance is the distance at which the lens has the smallest spot size. In most cases, this dis-
tance is also the required measuring distance.
With focusable optics the focus distance can be changed continuously within a predetermined range,
so the smallest possible spot size is always achieved.
5.5.1 Manually Focusable Optics
Release optics turn counterclockwise
Move optics in or out until the measured distance is found (see
Alignment onto the measuring object or via the optics pull-out in the
Spot Size Tables
, section
- Pulled optics: short measuring distance
- Inserted optics: long distance measurement
Lock optics turn clockwise (hand-screwed, without tools).
5.5.2 Motorized Focus Optics
(only M3)
The distance only can be set via software (see
SensorTools Software
)
