2. Clean the TDL
(a) Wrap a NEW Kimwipe around the end of the spatula and
moisten it with cleaning solution.
(b) WASH — Swipe the moistened Kimwipe across the TDL
emitter and detector lense once. (A single swipe is usually
sufficient to remove contaminants.)
(c) RINSE — Repeat steps a through b using new Kimwipes
moistened with deionized water instead of cleaning solu-
tion.
(d) DRY — Repeat steps a through b using a new, dry Kimwipes
to help remove any moisture remaining from the cleaning.
(e) Visually inspect the components for cleanliness. Clean
again if necessary.
3. Clean the IR Sensor
(a) Wrap a new Kimwipe around the end of the spatula and
moisten it with cleaning solution.
(b) WASH — Swipe the moistened Kimwipe across IR Sensor.
(A single swipe across the sensor is usually sufficient to
remove contaminants.)
(c) RINSE — Repeat steps a through b using new Kimwipes
moistened with deionized water instead of cleaning solu-
tion.
(d) DRY — Repeat steps a through b but use a new, dry
Kimwipe to help remove any moisture remaining from the

(e) Visually inspect the IR Sensor for cleanliness. Clean again
if necessary.
4. Additional Drying Time
