General maintenance instructions

 Dirt and moisture under the sensor cap can affect the functioning and shorten
the service life of the sensor cap. Therefore, make sure the working environ-
ment is clean and dry prior to removing the sensor cap.
 Please do not touch the sensor membrane unnecessarily with your fin-
gers.Touch the sensor cap at the sides only.
 Avoid any great mechanical stress of the sensor membrane (pressure,
scratches).
 Exposure to light, particularly daylight, of the interior of the sensor cap will,
by-and-by, affect the measurement characteristics and shorten the service
life of the sensor cap. Therefore, the interior of the sensor cap should not be
exposed to direct sunlight. Avoid any exposure to light that exceeds the
extent required for necessary maintenance and cleaning activities. Store dis-
mantled sensor caps in a light-protected environment only.
3.2 Exchanging the sensor cap
Note
Before removing the sensor cap, observe the general maintenance instructions
in section 3.1.
To exchange the sensor cap, proceed as follows:
1. Pull the sensor out of the sample.
2. Clean the outside of the sensor (see section 3.3.1).
3. Unscrew the protective hood from the sensor by hand.
4. Thoroughly clean and dry the sensor head once again.
5. Grasp the sensor cap on the sides (arrows in figure on the left) and
unscrew it from the sensor anti-clockwise.
6. Remove the sealing ring.
Caution:
Do not push any tools or other sharp objects between the sealing sur-
faces. This would damage the sealing surfaces and sealing ring.
7. Remove any remaining sealing grease from the seat of the sealing
ring using a dry lens-cleaning towel.
Wipe off any other deposits using a moist lens-cleaning towel.
Wipe dry using a dry lens-cleaning towel.
