HYSTERESIS
To compensate for fluctuation of the measured data, which
may cause the weather alarm to sound constantly if the
measured reading is close to your set level, a hysteresis
function has been implemented for each weather alarm.
For example, if the high temperature alarm is set to +77°F
and the current value moves to +77°F, the alarm will be
activated (if it has been enabled).
Now when the temperature drops to +76.8°F or below and
thereafter again increases to 77°F, the data will
be blinking, but no alarm will be activated. It has to drop to
below +75.2°F (with a pre-set hysteresis of 1.8°F) so that
the alarm can be produced again. Hysteresis values for the various weather data types
are given in the table.
Note:
The temperature or humidity data will keep flashing even after a key has been
pressed to stop the alarm or buzzer has been switched off to indicate that the current
weather condition is out of the pre-set limit(s)
