A sticker marks the setting.

4.6.1 When the probe alignment has to be set
● The measuring gap must be aligned in sample gas flow direction.
● The SR-unit must be fitted vertically.
Rotate the device flange to align the probe.
To change the measuring probe alignment:
1 Loosen the 4 screws on the mounting ring, (see Fig. 13).
2 Rotate the device flange:
– The measuring gap must point in flow direction.
– The device flange must be positioned so that the SR-unit can be fitted in a vertical
position.
3 Tighten the screws on the mounting ring again to fasten the device flange in this
position.
