readings.
The Omni Tilt & Distance Sensor Nodes must be oriented with at least one axis marked on the label parallel to the
horizontal plane, so that the tilting angle data can be easily recognized and interpreted.
6. General Maintenance and Notification
1) Once an Omni Tilt & Distance Sensor Node is installed in the field, please minimise any man-made
disturbance so that data quality can be maintained;
2) Radio communication will be impaired if the antenna is covered by metal or very moist soil material;
3) Please do take special notice on Laser Radiation matter with this lase node. Do NOT start into beam.
4) Due to the discharge characteristics of the recommended battery, a battery replacement should be carried out
when a node reported voltage reaches 2.7V, at which point you have approximately 3 weeks to change the
battery;
5) Our product will use all the possible capacity in a battery down to a stop (minimum) voltage, which has been
specified in the Features table. When this occurs, our WISENMESHNET protocol will send you a warning then it
will enter a deep sleep mode until a new battery is installed;
6) If the data from nodes are shown unexpected results or are not being sent back to the Wisen gateway, then please
carry out investigation using the following two stage procedure:
A. Remote Inspection of historical data, to identify the following:
a) Whether the heart-beat message has been sent back successfully at each time interval;
b) Whether the battery voltage is too low, if yes, please change the battery unit;
c) Whether the signal strength has become significantly weaker than it was previously. If yes, please
check the antenna has been screwed on firmly.
B. On-site Inspection: If all the above are good, please arrange an on-site inspection to check:
a) Whether the Omni Tilt & Distance Sensor Node has visible external damage;
