6.2.2 Lamp Cleaning and Changing
1.
Remove 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. It may help to use fine
tweezers; if so, do this very carefully so as not to damage 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 replace the
sensor cap and VOXI cover.
6.
Always re-calibrate the PID after cleaning the lamp and/or sensor.
