the camera head faces vertically downwards.
Number of degrees
The number of degrees displayed underneath
indicates the downward gradient of the pipe.
Example graphic: - 13° corresponds to a downward grade of 13°.
NOTE!
Example:
Camera head facing vertically upwards: + 90°
Camera head facing vertically downwards: -90°
Camera head is aligned parallel to the ground

13 Guide accessories
This section contains some recommendations based on our experience about the selection of guide accessories for the inspection in tubes and ducts.
As all pipes and chimney systems are different, the user has to decide about the guide
accessory in every single case. For the selection of the correct tool it is important to
consider that the guide accessory has to facilitate the introduction and the extraction of
the camera head, as well as an adequate guidance. The danger of jamming or getting
stuck in the tube has to be avoided.
NOTE!
The information given in this section only refers to the accessories.
Ø 1 ½ " – 2 "
Use the service camera without accessories.
Ø 2 " – 2,8 "
You can use the service camera without accessories. The
lens can be protected by the guidance sleeve. If there is
water and mud in the horizontal part, we recommend to use
the roller guide.
Ø 2,8 " – 3,9 "
The inspection is possible with the roller guide and without
it. Use the guidance weight for the vertical inspection or for
the inspection of downpipes.
Ø 3,9 " – 6,1 "
A centering brush can be used with the roller guide or without it and with the lens protection.
