Exchanging the

 

sensor cap

To exchange the sensor cap, proceed as follows:

Removing the

sensor cap

Mounting the

sensor cap

Before removing the sensor cap, observe the general mainte-
nance instructions in section 3.1.

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 
remove it by pulling it away from the sensor in a straight upward 
direction.

Caution:
Do not push any tools or other sharp objects between the sealing sur-
faces. This would damage the sealing surfaces and sealing ring.

6.

Check the front surface of the sensor for absolute cleanness and 
clean it if necessary (see section 3.3.2).

7.

Thoroughly clean the thread of the protective hood.

8.

Check the sealing ring for intactness and correct position.
The sealing ring has to be replaced if it is damaged.

9.

Aim the sensor head upwards and place the new sensor cap on the 
sensor. The locking device on the sensor head must be inserted into 
the receptacle on the inside of the sensor cap (see figure on the left).

10.

Put the protective hood on the sensor head and screw it tight by hand 
as far as it will go. A gap of approx. 0.8 mm remains between the pro-
tective hood and sensor.
The sensor is immediately ready to measure.
