ENVIRONMENT / OPERATING CONDITIONS
The End Device and Meter are designed to be fixed mounted and operated in a
clean and dry environment. Care should be taken to prevent the components of
your wireless system from being exposed to moisture, toxic chemicals, extreme
cold or hot temperature that are outside the specification listed in this manual.
The following is a list of basic good practice you should apply when operating
this Wireless System.
1. Do not operate the wireless meter in flammable or explosive
environments.
2. Do not use the wireless meter in medical, nuclear or other critical
application where failure can cause damage or harm.
3. Always operate the wireless meter within the recommended
environmental limits specified in the manual.
4. Do not operate the wireless meter with a battery or AC adapter other than
what’s supplied or specified in this manual or on the battery compartment
label.
5. Keep each wireless meter at least 8 inches (20 cm) from other radio
transmitters, antennas, and people.
6. The FCC approval for this meter specifies the specific antenna supplied
with this meter.
5.1 General Deployment Guidelines
1. Position Meter in a central location. When multiple End Devices are in
operation, position your Meter in a central space if possible in equal
distance to each End Device.
2. Test your system before permanent mounting. Try to move the devices to
different location around and mounting angles to determine what
installation achieves the best signal strength before permanently
mounting the End Device.
3. Move your system components higher off the floor and away from exterior
walls. The closer the End Device and Meter are, the greater the
interference and lose of signal strength will be. ????
4. Maintain a line-of-sight between antennas and keep Fresnel zone free of
obstruction. See Figure 5.2.
5. Maintain a constant ambient temperature environment. Exposing your
system components to extreme cold or hot temperatures, or sudden
changes in ambient conditions will have an effect on the performance of
your system.
6. As a general rule in buildings, head height or above is preferred. On the
other hand, an End Device which stays close to the floor may have its
range reduced by 50% to 90%.
