In Incremental Mode, alarms and warnings occur when the difference between two consecutive measurement values is less than
the minimum threshold value or greater than the maximum threshold value. This difference means the alarm threshold is a slope
instead of a fixed value.
The example shows three incidents labeled A, B, and C.
Incident A
: An SMS alarm is sent on the third consecutive set of measurements where the delta exceeds the alarm threshold
(reading no. 6-7, 7-8, 8-9).
Incident B
: No SMS alarm is sent. Only one consecutive set of measurements exceed the alarm threshold, while the requirement
set above is 3 consecutive measurements.
Incident C
: No SMS alarm is sent. Only one consecutive set of measurements exceed the alarm threshold, while the requirement
set above is 3 consecutive measurements.
In this scenario, SMS alarms are disabled for the rest of the day after the third SMS message is sent.
