WX 200 Weather Station
(630-1015)             Using Rainfall Rate/Amount     Faxback Doc. # 38348


The WX 200's rain gauge measures rain as it falls and automatically
calculates the rate of rainfall per hour.  To view the current rainfall
rate, repeatedly press < or > until the selection bar appears beneath the
RAIN symbol on the display.

NOTES:  The WX 200 is preset to display the rainfall rate in/h (inches
        per hour), but you can set it to measure in mm/h (millimeters
        per hour).

        If the current rate of rainfall is outside the weather station's
        operating measurement range (see "Specifications," Faxback Doc.
        # 38352), O.R. (out of range) appears on the display.

        We recommend you regularly check for and remove any debris that
        might have fallen into the rain gauge's cylinder.  Otherwise, rain
        might not properly drain into the gauge.

        To remove  the screen for easy cleaning, simply pull up on the
        string attached to the screen.  When you finish, place the screen
        back in the cylinder and press it down into place.


VIEWING THE DAILY AND CUMULATIVE RAINFALL RECORDS

To view the daily (yesterday's) rainfall amount, select the RAIN mode,
then press MEMORY so MEMORY appears on the display.

To view the cumulative amount of rainfall recorded in memory since the
last memory reset, press MEMORY again so TOTAL appears on the display.

To view the date and time that the cumulative rainfall memory was last
reset, press DOWN ARROW.  To recall the cumulative rainfall record, press
UP ARROW.


RESETTING THE CUMULATIVE RAINFALL RECORD

To reset the cumulative rainfall record in memory and record new data
beginning with the current condition, select that memory record then hold
down CLEAR for about 2 seconds until the weather station beeps.


USING THE HIGH RAINFALL RATE ALARM

You can set the weather station to sound an alarm when the rainfall rate
meets or exceeds a set condition (such as 1. in/h).  Each time rain falls
and meets or exceeds the set alarm condition, ALARM and HIGH flash on the
display and the weather station sounds an alarm steadily for 1 minute,
then once for about 5 seconds every minute until the rainfall rate no
longer meets the set condition.  To silence the alarm sooner, press any
key except LIGHT.

NOTES:  If you are using a mode other than RAIN when the high rainfall
        rate alarm sounds, a bar flashes beneath the RAIN symbol on the
        display but ALARM and HIGH do not appear.

        If you press a key to silence the alarm, the alarm stops sounding
        but the symbol bar (or ALARM and HIGH) continue to flash until the
        alarm condition is no longer met.

To view the current high rainfall rate alarm setting, select the RAIN
mode then press ALARM.  Press it again to recall the current rainfall
rate.

NOTE:  ---- appears when no alarm condition is set.


Setting the High Rainfall Rate Alarm

To set the high rainfall rate alarm to sound using the last set alarm
condition, select the RAIN mode and press ALARM so ALARM appears on the
display, then press CLEAR.  The last set alarm condition appears on the
display.

NOTE:  The first time you set the high rainfall rate alarm after you
       connect power or press RESET, the WX 200 selects a default alarm 
       condition of 0.00 in/hr (0 mm/hr).  If you use the default 
       condition, the WX 200 alerts you when any amount of rain falls.

To set a different condition for the high rainfall rate alarm, follow
these steps.

1.  If necessary, repeatedly press < or > to select the RAIN mode.

2.  Press ALARM so ALARM appears on the display.

3.  Hold down SET for about 2 seconds until the weather station beeps.
    The last set alarm condition flashes.

4.  Repeatedly press UP ARROW to increase the setting or DOWN ARROW
    to decrease it, then press SET to store it.

    NOTES:  If you do not press any button for about 60 seconds, the
            weather station beeps, stores the changes you have entered
            so far, then displays the current alarm condition.  If this
            happens, repeat Step 3 then try again.

            To rapidly increase or decrease the setting, hold down UP
            ARROW or DOWN ARROW.


Clearing the High Rainfall Rate Alarm Setting

To clear the high rainfall rate alarm condition so the alarm does not
sound, select the RAIN mode then press ALARM so ALARM appears on the
display, then press CLEAR.  ---- appears.
