Troubleshooting
No Readings or Inaccurate Readings
• Is there power to the WeatherStation Instrument?
• Are all the connections tight?
• Is the cable-run free of kinks?
• Is the wiring correct?
• Are there any obstructions in the wind channel?
Keep it free of spider webs, insects, dirt, and other debris.
Be careful not to puncture the waterproof film or scratch the reflector plate.
• Are the temperature and humidity sensors clean?
• Is there ice on the WeatherStation Instrument?
No GPS Fix
• Does the WeatherStation Instrument have a clear view of the sky?
Wind Readings Are Too Low
• Is the WeatherStation Instrument mounted forward and low on the boat/vehicle’s
hardtop in dead air?
Move the WeatherStation instrument farther back and higher (see Figure 12).
Rain Sensor Not Working
The rain sensor functions by detecting individual rain drops. To check whether the
rain sensor is working, use a gentle spray from a nozzled garden hose. This
should produce a reading which indicates that the sensor is active, but the reading
will not be calibrated. The sensor is calibrated only for true raindrops falling from a
cloud. Do not pour water on the sensor to check whether it is working. The sensor
depends on individual drops and will not respond properly to a stream of water.
