The Rearm is used to prevent the sensor from flickering between two
states. For example if the Warning High threshold for the temperature
sensor is set to 80 degrees and the sensor were to vary between 79 and
80 you could be faced with a very large number of emails, traps, and
events logged. The Rearm parameter prevents this by forcing the
temperature to drop by the Rearm before changing the state back to
normal. In this example if Rearm is set to 2 then the sensor would have
to drop from 80 down to 77 before the status would change from
Warning High back to normal.
Trap/Email Filter
Send Trap/Email On Normal Disable Feature: If not needed this
feature can be disabled by choosing 'disable' in the choice box, some
people may not want messages to signify normal conditions. Certain
applications and special projects may warrant messages being
generated when the sensor returns to a normal condition.
Delay Before Sending Trap/Email On Normal: There is also a delay
before sending Trap/Email on normal and is set in the same manner as
above. In this case the sensor is in the error state and will ignore
momentary fluctuations into the normal state.
Continuous time sensor is normal to report: This is for the elimination
of unnecessary messages during minor fluctuations. Enter the time in
seconds and press the set button. The amount of time that can be
entered is between 0 and 65535 seconds, which equals approximately
18 hours.
Example: an airflow or water flow sensor may have temporary drops in
readings that are normal operating characteristics, a logical time limit is
set to show abnormal conditions.
Minimum time between each Trap/Email: This is the time in minutes
between each Trap/Email. This is to prevent sending of multiple
Traps/Email, for a same event over a period of time.
Day of week Filter: With this option you can either enable or disable
the time period at which the ServSensor JR should send emails or
Traps. The time limit schedule can be configured so that the
ServSensor JR can send Mails/Traps during a fixed time interval. The
