Moon Phases Pressure Readings
History Graph:
• Read from left to right, your Pressure History Graph indicates
the rise and fall in air pressure over the past 24 hours.
• The numbers below represent the hour in which the
reading was taken. The “0h” is the current pressure level.
“-3h” was the reading taken three hours ago, compared to
current pressure.
•The graph will scroll continually. This cannot be turned o.
Your station provides Relative Barometric Pressure in:
• Numbers-programmable in the settings menu
• History Graph- provides pressure trend for the past 24 hours
Pressure number:
• Your station will acclimate to the correct pressure without
setting it yourself.
• You also have the option of setting the pressure number to
match your local reporting station by using the settings
menu.
• In the settings menu you can also select the pressure unit of
Inches of Mercury (inHg default) or Hecto Pascal (hPa).
•Your weather station will change to reflect the seasons.
• The trees and foliage will change to give you a fresh look.
• The dates are programmed into your weather station for an
automatic foliage change.

5 seconds to restart the station.
Position TX141TH-Bv3 Sensor
• To mount the sensor, use the hole at the top to either
hang it from the back using a nail, or insert one
mounting screw through the front of your sensor.
• Mount the TX141TH-Bv3 sensor on a north-facing
wall or in any shaded area. Under an eave or deck rail
is preferred.
• The maximum wireless transmission range to your
weather station is over 330 feet (100 meters) in open air,
not including walls or floors.
• Be sure the sensor is mounted vertically, to allow
moisture to drain out properly.
• Watch sensor mounting video:
http://bit.ly/TH_SensorMounting
Position Weather Station
• Pull out the stand and place on a flat surface.
• Or use the hanging holes on the back to mount on a wall.
• Choose a location 6 feet or more away from electronics
such as cordless phones, gaming systems, televisions,
microwaves, routers, etc.
• Place within range of the outdoor sensors (330 ft, 100m
open air).
• Obstacles such as walls, windows, stucco, concrete, and
large metal objects can reduce the range.
