Vantage Pro2 Troubleshooting Guide

self. If you need help, please see "One Year Limited Warranty" on page 40.

ABLE ROUBLESHOOTING
Unit is not receiving power. Check the power adapter connections
and/or replace batteries.
• ISS not plugged in (cabled station). See ISS manual.
• Sensors not transmitting (wireless station). See ISS (or other
transmitter) manual.
• Console not receiving (wireless station) - See "Troubleshooting
Reception Problems" on page 35.
• A reading has exceeded the limits indicated in the specifica-
tions table.
• Calibration numbers may be causing readings to exceed dis-
play limits. Check calibration number and adjust if necessary.
The console and display may not work below 32º F (0º C). Use an
External Temperature sensor in low-temperature locations or install
the console indoors.
If the console "locks up", reset the console by removing AC and bat-
tery power then restoring power. If this occurs frequently in an AC-
powered console, plug the AC power-adapter into a surge suppres-
sor.
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.
For low readings, remove the 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.
The problem may be with the anemometer. Test anemometer by
spinning wind cups. Check fields one-b and two-b on diagnostic
screen and call technical support.
Check calibration numbers for temperature. Remember, dew point
depends on temperature and outside humidity. Make sure they're
working.
