CLEANING THE PROBE SENSOR LENS
Dust and other minute particles of environmental debris can build up on
the probe sensor lens during normal use of the 9020.
The probe sensor lens should always be shiny and clear. Inspect the
lens frequently and clean as necessary. The lens should also be cleaned
as routine maintenance according to the two cleaning methods below.
NOTE: A dirty lens will affect the accuracy of temperature readings.
METHOD 1: REMOVING LIGHT DUST
(RECOMMENDED DAILY)
1. Advance the slide to extend the probe tip.
2. Leave the probe cover in place. Using a dry cotton swab, gently press
the probe cover against the sensor lens (Figure C). Loose debris on
the lens will adhere to the probe cover.
3. Move the slide back to its original position to remove the probe cover
and retract the probe tip. The 9020 is now ready for use.
