Specification and Alarm

Raise alarm on below lower spec readings – tick this box if you want to activate the low alarm and select
the value in the box immediately to the right. Note if the lower spec value is 0C, then the alarm can be
triggered at -0.1C, not 0.0C as this value is considered within specification.
Raise alarm on above upper spec readings – tick this box if you want to activate the high alarm and
select the value in the box immediately to the right. Note if the upper spec value is 50C, then the alarm
can be triggered at 50.1C, not 50.0C as this value is considered within specification.
Increment - the grouping size used for listing out-of-specification readings.

Alarm Type

This feature allows the user to specify the condition that will trigger an alarm.
Standard Alarm
Number of consecutive out of specification readings – the alarm is triggered if the readings are
consecutively over or under the specified threshold. For instance, if the upper spec is 50C and the value
for the number of consecutive out-of-spec readings is 3 and the logging interval is 10minutes, the readings
will need to be in excess of 50C for 30 minutes before the alarm is triggered. If the readings fluctuate
outside upper and lower threshold temperatures, the same rule applies (providing the appropriate "raise
alarm" box is ticked). Once reading(s) return inside alarm limits, the consecutive alarm is reset.
Total number of out of specification readings (cumulative) – the alarm is triggered if the total number of
out of spec readings equals the entered value. In this case the alarm is NOT reset if readings return to
within the specified parameters, and each out-of-spec reading is added to the previous one until the
number equals the entered value.
Do not set the Total number of out-of-spec readings value to be less than the Consecutive out-of-spec
readings as this will mean that the Consecutive out-of-spec readings alarm will never be triggered.
Degree-Minutes Alarm (Integrator Alarm)
The Degree-Minutes Alarm is a special feature that "integrates" temperature and time parameters into one
value.
