 9 Replacing the reference filter
1 Screw on circuit board
2 O-ring
3 Reference filter
4 Lamp holder
1. Remove both screws (item 1), and release the circuit board from the lamp holder (item
4).
2. Turn over the lamp holder and allow the filter (item 3) to fall into your hand.
3. Insert the new filter. In doing so, make sure that the "reflective" side is facing towards
the light source. Use the correct filter (reference filter) from the spare parts kit!
4. Fit the circuit board back on and tighten the screws slightly.
5. Reassemble the lamp module and mount it back on the assembly.
You must then recalibrate/readjust the measuring system.
