Placement for Maximum Accuracy
AcuRite sensors are sensitive to surrounding environmental conditions. Proper
placement of both the display and outdoor sensor are critical to the accuracy
and performance of this product.
Display Placement
Place the display in a dry area free of dirt and dust. Display
stands upright for tabletop use or is wall-mountable.
Outdoor Sensor Placement
Sensor must be placed outside to observe outdoor conditions.
Sensor is water resistant and is designed for general outdoor
use, however, to extend its life place the sensor in an area
protected from direct weather elements.
Hang the sensor using the integrated hang holes or hanger, or
by using string (not included) to hang it from a suitable location,
like a well covered tree branch. The best location is 4 to 8 feet
above the ground with permanent shade and plenty of fresh air
to circulate around the sensor.
Important Placement Guidelines
• To ensure accurate temperature measurement, place units out of direct
sunlight and away from any heat sources or vents.
• Display and outdoor sensor must be within 330 ft (100 m) of each other.
• To maximize wireless range, place units away from large metallic items, thick
walls, metal surfaces, or other objects that may limit wireless communication.
• To prevent wireless interference, place both units at least 3 ft (.9 m) away
from electronic devices (TV, computer, microwave, radio, etc.).
Setup is Complete
The sensor will now synchronize with the display. It may take a few minutes for
synchronization to complete. Please refer to the troubleshooting section of this
manual if anything appears to be functioning improperly.

OPERATION
Using the Weather Station
Learning Mode
Self-Calibrating Forecasting uses a unique algorithm to analyze changes in
pressure over a time period (called Learning Mode) to determine your altitude.
After 14 days, the Learning Mode icon disappears from the display screen. At
this point, the self-calibrated pressure is tuned in to your location and the unit is
ready for superior weather prediction.
Weather Forecast
AcuRite’s patented Self-Calibrating Forecasting provides your personal forecast
of weather conditions for the next 12 to 24 hours by collecting data from
the sensor in your backyard. It generates a forecast with pinpoint accuracy -
personalized for your exact location.

Barometric Pressure
Subtle variations in barometric pressure greatly affect the weather. This
weather station displays the current pressure with an arrow icon to indicate the
direction the pressure is trending (FALLING, STEADY, or RISING).
