Running the Software
Low alarms work the same way. For example, if the wind chill threshold is set for 30 ºF, the alarm begins sounding when the temperature drops to 30.0 º and will continue until the temperature again rises above 30.0º.
If you’re on battery power, the alarm will sound for two minutes only. If you’re using the AC adapter, the alarm will continue as long as the condition exists. The alarm will also sound again for each new alarm.
To silence a sounding alarm, edit the Alarm setup screen to either delete the alarm threshold or to modify the threshold so that the current conditions don’t cause an alarm.
Three special alarms
ET (Evapotranspiration)
ET is updated only once an hour, on the hour. If during a given hour the ET Value exceeds the alarm threshold, the ET alarm sounds at the end of that hour. This is true for daily, monthly, and yearly ET alarms. You must have the optional Solar Radiation Sensor to use this alarm.
Barometric Pressure
The Weather Envoy allows you to set two barometric pressure alarms: a “rise” alarm and a “fall” alarm. You may select any rate of change per hour between
0.01to 0.25 in Hg (0.1 to 6.4 mm Hg, 0.1 to 8.5 hPa/mb); the alarm will sound if the rate of change (in the selected direction) exceeds the threshold you set.
Time
The time alarm is a standard “alarm clock”. It sounds at the set tim. Make sure you choose AM or PM, if you’re in
Auto Download
You may set up the software to automatically download data at specified times each day (the software must be running and a constant connection to the data logger in the Envoy must be made).
