Troubleshooting Reception Problems
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
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.
Temperature
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
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
Chill
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
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.
Rain
No rain readings
Make sure cable-tie is removed from rain collector. See the ISS
manual.
Time
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.
