1  Introduction

The probe thermometer allows you to measure the temperature inside a refrigerator or freezer, while 
mounting the display on the outside of the refrigerator/freezer. 
Wireless signals cannot pass through a metal barrier. If your refrigerator/freezer is constructed of 
metal, the probe will have to be placed inside the refrigerator/freezer and the display/transmitter 
outside the refrigerator/freezer. 
In addition to the refrigerator/freezer application, the probe thermometer can be placed in any medium 
where temperature is required, including ground temperature, air temperature and water temperature. 
2  Getting Started 
Note:  The  power  up  sequence  must  be  performed  in  the  order  shown  in  this  section  (insert 
batteries in the remote transmitter(s) first, Display Console second). 
The WS-09 weather station consists of a display console (receiver), and two probe thermometers for 
the refrigerator/freezer.
