Installation
Das The pyrometer should be mounted, where it is not unnecessarily ex-
EN posed to smoke, heat or steam. Contamination of the lens leads to a
lower display of the measuring value. Therefore, make sure, that the lens
is always clean. The field of view of the pyrometer must remain free.
Any interference by objects can cause measurement errors.
1. Select a suitable location for the pyrometer. The following criteria
must be observed:
 The lens and the field of view of the pyrometer must be free of dirt,
smoke and steam. Otherwise, an air purge must be installed to pro-
tect the pyrometer from contamination.

The permissible operating temperature is 0 - 65 °C. At temperature
above 65 °C, a cooling jacket must be used. As cooling medium,
air or water are possible.
2. Check that the lens is clean. Assemble the pyrometer in the pro-
vided bracket and align the pyrometer to the measuring object. If
necessary, check the cooling medium and the maximum operating
temperature.
3. The pyrometer should be installed at 90 ° to the measured object,
if possible. The angle should not be less than 45 ° from the verti-
cal. The spot must be completely filled by the measured object.
4. Turn on the power supply of the pyrometer.
5. Focus the pyrometer
Pyrometer with through-lens sighting:
Focus the lens until the target and the target marker (distinctly
marked circled spot in the viewfinder) are both clearly visible.
Pyrometer with laser sighting:
Activate the laser spot light by pressing the mode button for 3 s.
Observe the laser safety instruction. Focus the lens until a clear
and round laser point is visible.
Pyrometer with camera
When aiming the pyrometer focus the sensing head until the video
