Note 2: Averaging is done using a walking window filter. This means the average
values used to generate alarms may differ from the averaged logged data which uses
simple averaging.
Note 3: The averaging filter is reset at power up and after making sensor setting
adjustments. During the initial period the reading will be an average of a shorter
period than the averaging time. This may result in unwanted alarms.
Note 4: To disable any of the alarm levels set the value to 0.00.
