A coverage test is considered correct if any of the SFs available on the network are able to deliver at
least half the packages sent. A coverage test is considered to be successful if the SF allowed in the
radio region receives an average of at least one third of the messages sent, and one of them should
receive at least half of the messages sent.
Note that performing the Radio signal coverage test takes approximately two minutes.
Note also that Radio Australia 500MHz works differently. See the wireless radio section in the
Gateway User Guide.
Safely closing the laser node
This is a very important step to ensure water tightness and durability of the laser node. Close the
cover by tightening the indicated 2 Nm torque.
The WI-SOS 480 Laser Distance Meter Node has undergone watertightness testing by an external
laboratory and is rated IP67 (One meter for 30 minutes) and IP68 for extended immersion (One
meter for seven days).
To guarantee watertightness, you must ensure that:
●
The box is closed in a cross-shaped order after sensor connection. All the screws must first
be inserted and screwed in until they are connected to the box and then adjusted using the
torque wrench. If these steps are not followed, the base faces and cover may not be parallel,
screwing may become more difficult and the screw threads or the Helicoil inserts may be
damaged. Moreover, the toric joint (seal) may not be properly sealed and the degree of
protection against water intrusion (IP) could not be guaranteed
●
The box is screwed at 2 Nm using a torque screwdriver (e.g. Ref. 1227107 from WERA)
●
The antenna is mounted. If it is not, the antenna connector should be covered with a cap
●
The sealing ring has not been manipulated either physically or chemically
●
The sealing cap USB connector is coiled
If any of these conditions are not met, or if one or several components (e.g. Gore valve) are
damaged, IP67 and IP68 ratings cannot be guaranteed.
Should the laser node need further sealing due to placement in an extreme environment or in a
floodable manhole, additional sealants will be required to close the box (e.g. Sikaflex products).
