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.
