Call up the main menu (Figure 3, Page 9) on the display terminal by pressing "m" two
times Press "2" for Output Format. Then press "1" for observation display (Figure 4,
Page 9).
Obtain current values for temperature and humidity from the nearest airport or weather
service facility, and see that the values shown on the main display agree approximately
with them.
To simulate a change in temperature and humidity, lean close to the sensor (or to the
solar shield) and breathe onto the sensor until you see a corresponding change in the
displayed temperature and humidity values.
2.4.5 Rain Gauge
Connect the rain gauge cable to the terminal strip on the data acquisition module. This
sensor has a two conductor cable. Connect one conductor to a GROUND terminal and
the other conductor to terminal P3.
While watching the observation display, manually tip the bucket or add a tablespoon or
two of water into the funnel until the bucket tips. If the rainfall amount displayed on the
screen increases by the expected increment (usually 0.01" or 0.254 mm) each time you
tip the bucket, your rain gauge is working properly.
3.0 OPERATION
The WS-16-A Weather Station collects and logs data automatically, requiring little user
input. Ultimate control, however, is provided by the interactive user interface, which
allows the user to direct the WS-16-A to perform certain specific functions by choosing
one of the six options offered on the main menu (Figure 3, Page 9).
3.1 Software
The firmware in the WS-16-A contains all of the programs required to use the weather
station with a PC operating in communications mode (such as HyperTerminal in
Windows). The WS-16-A and the PC communicate through the RS232 serial interface
cable installed between the data acquisition module and a serial port of the computer
(usually Com 1 or Com 2). To help you get started if you are using Windows
98/2000/XP, we have provided a quick start disk that automatically opens the
HyperTerminal program with all the proper settings for communicating with the
WS-16-A using Com 1 or Com 2.
