Troubleshooting and Maintenance

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

• ISS is 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 dehumidifier.

Check calibration number and adjust if necessary. If inside

humidity is low, and inside temperature is too high, see

temperature, below. Turn off the console backlight.

Wind

Wind speed reading

seems too low.

Remove wind cups and check for friction sources. Check the ISS

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 wind cups. Test by spinning. Check

the corresponding wind fields in the diagnostic screens and call

technical support. (See “Screen 1: Statistical Diagnostic Screen”

on page 39.)

Wind reading is dashed

out

Check reception. See Reception Problems below.

Dew

Dew Point reading

seems too high or too

low

Check calibration numbers for temperature. Dew point depends on

outside temperature and humidity. Make sure both sensors are

working.
