Pressure threshold setting   

The pressure threshold (the negative or positive rate of change of pressure signifying a change in the 
weather) can be adjusted by the user from level 2 to level 4 (default level 2 mbar/hour).   
 
The  lower  the  level  pressure  threshold  setting,  the  higher  sensitivity  for  weather  forecast  changes. 
Locations  that  experience  frequent  changes  in  air  pressure  require  a  higher  setting  compared  to 
locations where the air pressure is typically stagnant.

Pressure Graph 

Note: 

The  weather  station  bar  graph  flashes  from  right  to  left  to  prevent  screen  burn  in.  This 

feature cannot be turned off. 
 
The pressure graph displays the barometric pressure for the last 24 hours.    Each bar represents three 
hours.

Restoring Lost Outdoor Temperature and Humidity Sensor 

If the signal is lost between the remote sensor (or transmitter) and the display console (or the receiver), 
to  resynchronize,  while  in  normal  mode,  press  and  hold  the 

+

  key  for  10  seconds.  The  transmitter 

search icon will appear in the outdoor temperature and humidity section.    Please wait several minutes 

for  the  search  icon 

  to  turn  off  and  the  remote  sensor  reports  in.  Do  not  touch  any  buttons until 

synchronization is complete.

Glossary of Terms 

 

Term 

Definition 

Absolute Barometric 
Pressure 

Relative barometric pressure, corrected to sea-level.    To compare 
pressure conditions from one location to another, meteorologists correct 
pressure to sea-level conditions. Because the air pressure decreases as 
you rise in altitude, the sea-level corrected pressure (the pressure your 
location would be at if located at sea-level) is generally higher than your 
measured pressure. 

Accuracy 

Accuracy is defined as the ability of a measurement to match the actual 
value of the quantity being measured. 

HectoPascals (hPa) 

Pressure units in SI (international system) units of measurement. Same 
as millibars (1 hPa = 1 mbar) 

Hygrometer 

A hygrometer is a device that measures relative humidity.    Relative 
humidity is a term used to describe the amount or percentage of water
