Pyrometer wire connection
6.2.2 Align pyrometer
The pyrometer is equipped with an LED pilot light for accurate alignment of
the sensor with the object to be measured. Align the pyrometer with the object
to be measured as follows:
1. Switch on the supply voltage to the pyrometer.
2. Allow a starting time of approx. 5 minutes for thermo-stabilization. Than
the pyrometer has stabilised and is ready to work with the given
accuracy.
3. Switch on the pilot light by pressing the push button at the rear side.
Make sure that there is nothing in the path of rays.
Note: In order to avoid measuring errors, the area of the pilot light must
not be larger than the object to be measured
4. If you have a pyrometer with vario optic head, adjust the necessary
measuring distance (see page 18).
Note:
The pyrometer is thus aligned and ready for the temperature
measurement.
