FAQ Diver-NETZ
Diver-NETZ Mobile and Diver-NETZ Static
How do I store and handle the equipment?
Before installation, the equipment should be stored in a safe place. However, it is important to know what the
effects of storage are for the instrument. The Diver-DXT has a built-in battery which cannot be switched off. This
means that the instrument is always active and consumes energy from the battery. The total battery capacity will
be reduced by approximately 4% per year in storage conditions. Another important storage condition is the ambient
temperature. If the instrument is stored for a long period of time (more than one month) it is best to store the
instrument in a dark place at room temperature.
The instrument is tested for transport conditions according to ASTM D 4169-09 DC 2 (transport simulation test). This
globally accepted standard ensures no damage if the instrument is transported under normal conditions in its own
packaging. Keep the instrument in the original packaging until it is installed in the field. The instrument is also tested
according to MIL-STD-810 and ASTM D 3332 (shock and vibration tests). This test simulates the mechanical shocks
and vibrations during installation of the Diver-DXT. Although the equipment can handle these conditions, it is better
to avoid any abnormal shocks and vibrations if possible. The Diver-DXT has sensors which need to be handled with
care.
What is the radio range between the Diver-Gate(M/S) and the Diver-DXT?
The radio technology of the Diver-DXT and the Diver-Gate(M/S) makes use of the ISM (Industrial, Scientific and
Medical) band. Specifically, the 2.4 GHz radio frequency is used. This radio band is unlicensed, which means that
the frequencies are open for public use and require no registration or payment for usage of the frequency. In order
to comply with the regulations, the output power of the devices is regulated. This regulation may cause limited
range of the radio device. Typically, the radio range of the Diver-DXT device is about 500 meters (1,300 ft) line-of-
sight (LOS).
Certain characteristics inherent to the environment where the system is deployed may affect the range of the
radio system. This includes, but is not limited to, rain, snow, fog, large bodies of water, trees, forests, metal well
protective covers, buildings, atmospheric conditions, ambient frequencies, noise, electromagnetic fields and
general conditions of the terrain. Besides, the positioning of the Diver-DXT may affect the range of the radio system
as well.
To maximize the performance of the radio devices, it is recommended to place the Diver-DXT in an area where it is
possible to “see” the device without obstacles in between. This is not mandatory, but improves the performance of
the system. If this condition is not met, the performance of the system may be reduced. We therefore recommend a
site assessment in order to plan and optimize the deployment of devices.
Can I use my existing Diver Data Cables?
Yes, you can use your existing DDC cables. However, the connector of the DDC cable needs to be modified by SWS.
What is the maximum cable length that can be used?
The maximum cable length is 300 meters.
How long does the battery in the Diver-DXT last?
The nominal battery lifespan is 5 years. The battery can be replaced SWS.
