Vantage Vue Troubleshooting Guide

37

While we have tested the Vantage Vue radio extensively, each site and each 
installation presents its own issues and challenges. Obstructions, particularly metallic 
ones, can cut down your station’s reception distance. Be sure to test reception 
between the console and ISS in the locations you intend to install them before 
permanently mounting your ISS.
The console’s reception status displays as an antenna icon above the graph portion of 
the console screen
• The antenna icon displays with waves flashing around it when the 

console is receiving data from the ISS.

• The antenna icon displays alone when the console is trying to re-

establish a lost connection. When no data packets have been received 
for 10 minutes, the console dashes-out any missing sensor readings.

• The antenna icon disappears when the connection between the ISS and console is 

lost. The console tries for 10 minutes to re-establish a connection, then stops trying 
to connect with the ISS for 15 minutes, and then redisplays the antenna alone 

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.

Temperature

Outside temperature 
reading seems too high

Check calibration number and adjust if necessary. The ISS may 
need to be relocated away from radiant heat sources. See the ISS 
Installation manual.

Inside temperature 
sensor reading seems 
too high

Move the console out of direct sunlight. Make sure the console or 
sensor is not in contact with an exterior wall that heats up in 
sunlight or when outside temperature rises. Make sure the console 
or sensor is not near a heater or other internal heat source (lamps, 
appliances, etc.). Check calibration number and adjust if 
necessary.

Outside temperature 
seems too low

Check calibration number and adjust if necessary. Sprinklers may 
be hitting the ISS radiation shield. Relocate. See ISS manual.

Inside temperature 
sensor reading seems 
too low

Make sure the console temperature sensor is not in contact with 
an exterior wall that cools down when outside temperature drops. 
Make sure the console temperature sensor is not near an air con-
ditioning vent. Check calibration number and adjust if necessary. 

Chill

Wind chill reading 
seems too high or too 
low

Check calibration numbers for temperature. Wind chill depends on 
temperature and wind speed. Make sure they’re working.

Heat

Heat Index reading 
seems too high or too 
low

Check calibration numbers for temperature. The heat index 
depends on temperature and outside humidity. Make sure the sen-
sors are working.

Rain

No rain readings

Make sure the rain funnel is not clogged with debris. See the ISS 
manual. 

Time

Incorrect times for 
sunrise and sunset

Check your latitude, longitude, time zone, and daylight saving time 
settings. Sunrise and sunset times are calculated from the console 
using all of these settings.
