Study Notes
Meteorological Elements Measured by Pocket Weather Tracker
- Measures wind direction and speed
- Records cross wind, head wind, and tail wind
- Tracks dry bulb and dew point temperatures
- Calculates wind chill effects
- Assesses relative humidity levels
- Evaluates heat stress conditions
- Monitors barometric pressure
- Measures altitude and density altitude
Setting up the Pocket Weather Tracker
- Insert batteries securely using plastic shim to hold them in place
- Set date and time during first use or battery replacement
- Calibrate the digital compass after each battery replacement to ensure accurate readings:
- Power on and select compass calibration
- Hold upright and rotate slowly three times
- Calibration confirmation displayed
- Set barometric pressure and altitude:
- Use station pressure to calculate altitude and adjust for accurate readings
- Input QNH or altitude as a reference for pressure calculations
- After setups, system readiness confirmed.
Operating Procedure
- Remove cover of wind impeller before use
- Stand windward for three minutes to gather data effectively
- Use up/down buttons to view different element readings
Data Downloading Procedure
- Insert PWT into Interface and secure with rubber band
- Connect RS-232 cable to computer's USB port
- Start the computer and select the Kestrel Communicator program, installing from CD if necessary
- Monitor uploading progress → takes approximately 2½ minutes
- Save uploaded data on the computer for future reference and add remarks if needed
Loading and Clearing Data
- Previously saved remarks displayed while loading saved data
- Clear the Kestrel Tracker memory with confirmation request
Observations at Operational Location
- Met Assistant uses Pocket Weather Tracker for current weather observations where conventional observatories are unavailable
- Data is either downloaded directly to a computer or stored within the device
- Regular maintenance recommended: clean with a soft cloth and check battery voltage frequently
