1.Important instructions prior to use
Please read these instructions carefully and ensure that the required conditions specified
in this document are met before using the product. Each of our edge devices includes this
information inside the packaging
General warnings
●
Follow these precautions to avoid a battery explosion or leakage of flammable liquid or gas:
○
Use the correct battery type. Dispose of the batteries according to instructions. Do not
dispose of the batteries by throwing them into a fire or a hot oven, or mechanically crush or cut
them.
○
Do not leave the batteries in an extremely high-temperature environment.
○
Do not subject the batteries to extremely low air pressure. It may result in an explosion or
leakage of flammable liquid or gas.
○
Do not short circuit the batteries. This will blow the protection fuse.
●
Batteries and equipment to be connected via the data port must meet IEC 62368-1 ES1 and PS1
requirements.
●
Equipment to be installed in restricted access areas.

Description
Caution. Do not proceed until the instructions are clearly understood and all required
conditions are met.
Read the instructions for use carefully before using.
Caution, hot surface.
According to the European Union WEEE Directive 2012/19/EU, this product and its batteries
should not be discarded as unsorted waste.
Please send them to separate collection facilities for recovery and recycling.
It is your responsibility to dispose of your waste equipment and batteries properly. The
correct disposal of your old equipment and batteries will help prevent potential negative
consequences for the environment and human health.

2.Device Overview
This user guide explains how to configure and operate Worldsensing’s Loadsensing Wireless
Tiltmeter90. Further technical descriptions are available in the datasheets .
The Loadsensing Wireless Tilt90 is a long-range, low-power wireless data logger with a 3
axes tiltmeter. It measures 3-axis inclination with respect to gravity’s direction and reports
the two axes of rotation from the horizontal plane in any orientation.
There are two models of Tilt90, the one with an external antenna (LS-G6-TIL90-X) and the
one with an internal antenna (LS-G6-TIL90-I), which dier from specifications (see the
specifications on next chapter). Model LS-G6-TIL90-I will be released shortly.
The wireless tilt90 can be used connected to the CMT or as a standalone logger for manual
monitoring, and can be easily configured by connecting it to an Android phone with a USB
cable.
Tiltmeters for monitoring applications provide measurements of changes from the vertical
level, either on the ground or in structures. This makes them key sensors to monitor
inclinations, movements and dierential settlements of slopes or infrastructures.
Tiltmeters have been extensively used in landslides, embankments and mines monitoring
to control the stability of the slopes.

Vibration resistance
Do not subject the device to
accelerations that exceed
higher levels of accelerations
than +-8g. For higher levels
we recommend to use the LS
G6-TIL90 I.
Do not subject the device to
accelerations that exceed higher
levels of accelerations than +-80g.
Test: Random vibration test railroad

Impact resistance*
Drop from 1 meter onto a concrete surface (20 000g).
* The tiltmeter has good impact resistance. However it should be treated carefully like any precision instrument.
