7.1 LAMP CLEANING AND CHANGING

1. Unscrew the Sensor Cap and pull the sensor straight
out, using a slight rocking motion if necessary.
2. Put on finger gloves and pull out the lamp. Insert
a new lamp, or clean the existing lamp as described
below.
3. Use a cotton swab wetted with methanol to clean
the flat window surface of the lamp. If greasy dirt is
hard to remove using methanol, the window can be
polished using fine alumina powder polishing paste.
4. Use a clean tissue to wipe the lamp window again.
5. Re-insert the cleaned lamp, plug in the sensor and
screw on the sensor cap.
Note: Always re-calibrate the PID after cleaning the lamp and/or sensor.
