Measurement Location Nodes in Policy Designer

The Properties window for a Measurement Location node contains the items that are described in the following table.

Item	Description
Primary Record check box	Specifies whether or not the node represents a primary record.
Trigger check box	Specifies whether or not changes to the record that is associated with the node will result in policy execution.

The following example illustrates how you can use the Measurement Location node with successor nodes to evaluate fields in a Measurement Location record and the collection of readings associated with a Measurement Location record. Consider the following nodes and connections.

In this example, the Measurement Location node is connected to a Max Calculation node and an Equal Condition node.

As shown in the following image, you can use the Properties window for the Max node to select the Measurement Location node and the Readings option. When this option is selected, the Max node evaluates the readings that are associated with the Measurement Location record and returns the reading with the highest value.

You can also select a field from the Measurement Location family as an input for a successor node. As shown in the following image, you can use the Properties window for the Equal node to select the ML Type field in the Measurement Location family. This node evaluates whether or not the ML Type field contains the exact value Numeric.
