Introduction
The Ambient Weather YG315 is a classic three-in-one weather station designed to provide accurate readings of temperature, humidity, and barometric pressure. Housed in a solid wood base with a cherry lacquer finish, this traditional instrument is suitable for indoor use and offers a timeless aesthetic while delivering essential weather data.
Product Overview
The YG315 weather station integrates three key instruments:
- Thermometer: Measures ambient air temperature in Fahrenheit.
- Hygrometer: Measures relative humidity.
- Barometer: Measures atmospheric pressure, indicating weather trends.
Each dial measures 2.5 inches in diameter, ensuring clear readability. The unit can be mounted either horizontally or vertically to suit your space.

Setup
1. Unpacking
Carefully remove the weather station from its packaging. Inspect the unit for any signs of damage. Retain packaging for future transport or storage.
2. Placement
For accurate readings, place the weather station indoors in a location that is:
- Away from direct sunlight.
- Away from heat sources (e.g., radiators, vents, appliances).
- In an area with good air circulation.
- Not near windows or doors that are frequently opened, as this can cause sudden temperature and humidity fluctuations.
The unit can be hung on a wall using the keyhole slot on the back. It supports both horizontal and vertical orientations.
3. Barometer Calibration
The barometer requires initial calibration to your local atmospheric pressure for accurate readings. This is a one-time adjustment unless the unit is moved to a significantly different altitude.
- Obtain the current barometric pressure for your exact location from a reliable source. This can be a local weather service, airport weather report, or another accurately calibrated barometer.
- Locate the small adjustment screw on the back of the barometer dial.
- Using a small flat-head screwdriver, carefully turn the adjustment screw until the barometer needle points to your local barometric pressure reading. Turn clockwise to increase the reading and counter-clockwise to decrease it. Avoid applying excessive force.
- Tap the glass face of the barometer gently a few times to allow the mechanism to settle. Re-check the reading and adjust if needed.
Allow the thermometer and hygrometer approximately 1-2 hours to acclimate to the room's conditions before taking readings.
Operating Instructions
1. Thermometer

Image: Detailed view of the thermometer dial, displaying temperature in degrees Fahrenheit from -40°F to 140°F.
The thermometer measures the ambient air temperature in degrees Fahrenheit. The needle indicates the current temperature. For accurate readings, ensure the unit is not exposed to direct heat sources or drafts.
2. Hygrometer

Image: Detailed view of the hygrometer dial, indicating relative humidity from 0% to 100% with a "NORMAL" range marked.
The hygrometer measures the relative humidity in the air, expressed as a percentage. The needle points to the current humidity level. Optimal indoor humidity levels typically fall within the "NORMAL" range indicated on the dial.
3. Barometer

The barometer measures atmospheric pressure. Changes in pressure indicate changes in weather patterns. A rising barometer generally suggests improving weather, while a falling barometer often indicates approaching stormy or unsettled weather. The dial includes small weather icons to help interpret these trends.
- Rising Pressure: Indicates fair or clearing weather.
- Falling Pressure: Indicates approaching unsettled or stormy weather.
- Steady Pressure: Indicates stable weather conditions.
Maintenance
- Cleaning: Wipe the unit with a soft, dry cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish and instrument dials.
- Location: Periodically check the placement of your weather station to ensure it remains in an optimal environment for accurate readings.
- No User Serviceable Parts: The internal mechanisms of the thermometer, hygrometer, and barometer are not designed for user maintenance. Do not attempt to disassemble the unit.
Troubleshooting
Inaccurate Barometer Reading
If the barometer reading appears inaccurate, it likely requires re-calibration. Refer to the "Barometer Calibration" section under Setup. Ensure you are using a reliable local pressure source for comparison. Remember to gently tap the glass after adjustment to allow the needle to settle.
Inaccurate Thermometer or Hygrometer Reading
Allow the unit sufficient time (1-2 hours) to acclimate to its environment. Ensure the weather station is placed away from direct sunlight, heat sources, or strong drafts, which can affect readings.
