Definition
Customer can define a period in the beginning and in the end of shipments where the alarm functionality is inactive. During the ignore period temperature date is still being recorded and will be visible.
Example of use cases
In the beginning of shipments: Product is placed in a truck or package for transport that is not preconditioned.
In the end of shipments: There is a known delay at destination from the time logger is removed from product and until the stop button is pressed on all loggers.
How to set ignore period?
The ignore period is set when creating a new shipment.
When creating a new shipment it is possible to select ignore period for the beginning and end of shipments by selecting value from drop down list.
Alternatively the ignore period can be defined in shipment templates and pre-defined for all shipments created using that template.
How is it displayed to a user?
SCM UI: Single shipment view - Info tab
Ignore periods are shown on the information panel on the left hand side.
SCM UI: Single shipment view - Chart tab
An event is displayed when monitoring starts / ends. There are also no temperature boundaries (dashed lines) on the graph within the ignore period.

How it works
When a shipment is created all of the shipment configuration is sent to the logger - including the ignore period. Therefore, the ignore period works on a logger level rather than on a shipment level.
Once a logger enters shipment mode by selected shipping method (start button, geofence, specify time) the ignore period starts counting. All measurements within the ignore period will not trigger any alerts.
See below an example showing a shipment with 30 minute ignore period in the beginning of shipment.
Ignore period (end)
Ignore period in the end is a bit different from the ignore period in the beginning because it is handled in post processing of the shipment, i.e. after the shipment is delivered.
The logger will send out a notification if an excursion occurs like it normally would as the time of delivery is unknown.
Post processing will check for and clear any excursion from the shipment that occur during ignore period in the end.
Note: The events generated within the ignore period in the end will not be cleared for the event log and excursion boundaries. See below.
Edge case
Measurements that coincide exactly with timestamp of monitoring starts and end are considered to be outside ignore period and will result in excursions if outside temperature boundaries.
See below example
Excursion set to be triggered immediately.
Ignore period: 10 mins
Shipment Start: 1:00 PM
Monitoring Start: 1:10 PM
This results in no measurement being recorded within the 10 minute ignore period.
