Vantage Vue Troubleshooting Guide
While your Vantage Vue weather station is designed to provide years of trouble-free
operation, occasional problems may arise. If you are having a problem with your
station, please consult this troubleshooting guide before calling Davis technical
support. You may be able to quickly solve the problem yourself. Please see
“Contacting Davis Technical Support” on page 52.
Note: Refer to the ISS Installation Manual for additional troubleshooting information.
TABLE 4-1: TROUBLESHOOTING GUIDE
Problem Solution
Display
Display is blank
Unit is not receiving power. Check the power adapter connections
and/or replace batteries.
Display shows dashes
in place of weather data
• Station not transmitting. See ISS manual.
• Console not receiving - See “Troubleshooting Reception
Problems” on page 37.
• A reading has exceeded the limits indicated in the
specifications table.Calibration numbers may be causing
readings to exceed display limits. Check calibration number
and adjust if necessary.
Console is sluggish or
does not work at low
temperatures
The console and display may not work below 32° F (0° C). Use an
external temperature sensor in low-temperature locations or install
the console indoors.
Display “locks up”
Reset the console by removing AC and battery power then
restoring power. If this occurs frequently in an AC-powered
console, plug the AC power adapter into a surge suppressor, or
use batteries. (They will last up to a year.)
Humidity
Inside humidity seems
too high or too low
Make sure the console is not near a humidifier or de-humidifier.
Check calibration number and adjust if necessary. If inside
humidity is low, and inside temperature is too high, see “inside
temp” below. Also make sure the console backlight is not on.
Wind Speed
Wind speed reading
seems too high or too
low.
For low readings, remove wind cups and check for friction sources.
Check the anemometer location. Is it sheltered from the wind? See
ISS manual for additional wind speed troubleshooting information.
Wind speed reads 0
either all the time or
intermittently
The problem may be with the anemometer. Test anemometer by
spinning wind cups. Check the corresponding wind fields in the
diagnostic screens and call technical support.
Wind Direction
Wind direction reading
is dashed out
Check reception. See Reception Problems below.
Wind direction always
says north
Could be an ISS problem, especially if outside temperature is
dashed out as well. See the ISS manual for troubleshooting
information
