Vantage Pro2 Troubleshooting Guide

38

While we have tested the Wireless Vantage Pro2 radio extensively, each 
site and each installation presents its own issues and challenges. Obstruc-
tions, particularly metallic ones, will often cut down your station’s recep-
tion distance. Be sure to test reception between the console and ISS, in the 
locations you intend to install them, or before permanently mounting your 
ISS or other transmitter(s).

Dew Point reading seems 

too high or too low

Check calibration numbers for temperature. Remember, dew point 

depends on temperature and outside humidity. Make sure they’re 

working.

Outside temperature sensor 

reading seems too high

Check calibration number and adjust if necessary. ISS or temp sen-

sor may need to be relocated. See ISS or other transmitter manual.

Inside temperature sensor 

reading seems too high

Move the console out of direct sunlight. Make sure that the console 

or sensor is not in contact with an exterior wall that heats up in sun-

light or when outside temperature rises. Make sure the console or 

sensor is not near a heater or other internal heat source (lamps, ap-

pliances, etc.). Also make sure the console backlight is not on. 

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 or other temperature sensor is not in contact 

with an exterior wall that cools down when outside temperature 

drops. Make sure the console or other temperature sensor is not 

near an air conditioning vent. Check calibration number and adjust 

if necessary. 

Wind direction reading is 

dashed out

•

Wireless model - check reception. See Reception Problems 

below.

•

Cabled model - cable may be faulty.

If these steps do not reveal the problem, the anemometer may be 

faulty. Call technical support for return authorization.

Wind direction always says 

north

Usually an ISS problem, especially if outside temperature is dashed 

out as well. See the ISS manual for troubleshooting information

Wind chill reading seems too 

high or too low

Check calibration numbers for temperature. Remember, wind chill 

depends on temperature and wind speed. Make sure they’re work-

ing.

Heat Index reading seems 

too high or too low

Check calibration numbers for temperature. Remember, the heat in-

dex depends on temperature and outside humidity. Make sure 

they’re working.

No rain readings

Make sure cable-tie is removed from rain collector. See the ISS 

manual. 

Incorrect times for sunrise 

and sunset

Check your latitude, longitude, time zone, and daylight savings time 

settings. Sunrise and sunset times are calculated from the console 

using all of these settings.
