Setting the Vario optic
Adjust the necessary measuring distance with the help of the vario optic as follows:
1. If necessary switch on the pilot light by pressing the push button at the rear side.
2. Loosen the ring nut (item 1, Fig. 10) by turning it in a counter-clockwise direction.
3. Move the vario optic (item 2, Fig. 10) forwards and/or backwards, in order to adjust
the pyrometer to the required measuring distance.
Note:
eration of the pyrometer
The size of the pilot light is identical to the size of the measuring field. The measuring
field may not be larger than the object to be measured at the adjusted distance!
4. After adjusting the measuring distance, lock the annular nut by turning it in a
clockwise direction.
The vario optic is thus adjusted to the required measuring distance.
