### Leica Feature Parameters in Offline Mode

When using a Leica Tracker in online mode to generate feature commands, PC-DMIS automatically inserts the following information into the Edit window inside those feature commands:

- RMS: Root Mean Squared value of each hit.

- Probe Type: The type of probe used to measure the feature.

- Time Stamp: The time the feature was executed or learned. PC-DMIS only updates this when it actually measures a feature in online mode.

- Environmental Conditions: Information such as temperature, pressure, and humidity.

In offline mode PC-DMIS behaves differently. These Leica Tracker items only appear after you select the Show tracker parameters in offline check box on the General tab of the Setup Options dialog box. These parameters will only appear for new feature commands inserted into the part program after you have selected this option. Previously measured features will remain unaffected except for a permanent structure change adding in an empty Tracker Parameter group into each feature command.

Note: Selecting this check box performs a permanent change to your part program structure for inserted feature commands regardless of whether or not you later clear this check box. For example, if you clear this check box after you've already used it for some features, newly inserted features will still contain a Tracker Parameter group; although that group will not contain any group items.
