Meade Instruments TE688W - Manual (Page 10)

OPERATION
Once the main unit is powered, the display will show all
available LCD segments for a moment.
IMPORTANT: All of the display functions will be locked,
allowing setting of your local altitude and pressure parameters
by pressing the UP (? ) or DOWN (? ) and MODE buttons.
The locked display will show the pressure icon and abbreviation
“inHg” flashing in the Weather Forecast/ Pressure Window,
default time in Clock Window and channel 1’s temperature and
humidity readings in Temperature/ Humidity Window.
If pressure and altitude are not configured during this time, the
unit will self-calibrate in a few minutes and show the default
settings for the pressure and altitude (sea level) and all remote
weather sensors readings.
GETTING STARTED
WEATHER FORECAST
This unit is capable of detecting the atmospheric pressure
changes. Based on collected weather data, it forecasts the
weather for the next 12 to 24 hours.
When the
display
shows...
Forecast is... Sunny Cloudy Rainy
Heavy
Rainy
Snowy
Heavy
Snowy Partly
Cloudy
NOTE: The weather forecast accuracy is approximately 70%.
The main unit display shows forecasted (predicted) not
current conditions. The SUNNY icon indicates clear weather,
even when displayed during the nighttime.
PRESSURE OPERATION
The pressure window displays: current barometric pressure, sea
level pressure, and weather forecast. The information contains a
number of historical statistics: pressure/ temperature/ humidity
history bar-chart for the past 24 hours
Pressure can be measured in inHg, hPa/mBar or mmHg, and
altitude is determined in either meters or feet.
IMPORTANT: There are three viewing options available:
barometric pressure SEA LEVEL or LOCAL and ALTITUDE.
Local pressure is a measured value (can’t be adjusted) while
Sea Level & Altitude are variables that you can enter. It is
advisable to select and program only one of the variables and to
allow the unit to calculate the third value.
