Measurement Profiles

Clicking the Measure button initiates the currently selected measurement profile, and it concludes when the profile is completed. The current selected Measurement Profile is shown as the selected item in the drop-down list. This selection can also be adjusted by clicking on one of the 4 predefined quick selects.

Measurement profiles define both:

 

How a Measurement Profile Works

The properties of the selected measurement profile can be edited with this button:

The Single Pt. To SA measurement profile is the most basic laser tracker measurement profile. It defines how a single "Discrete Point" measurement is taken.

  1. In this case the Acquisition builds a single "Discrete Point" made 50 sample taken at a rate of 100Hz or a 1/2 second averaged measurement and returns the best point.

  2. The Operation of the measurement profile then is to send this single averaged or discrete Measurement to SA to be saved in the tree.

 

The specifics for this Discrete Point's Acquisition profile are as follows: 

 

Spatial Scan is another common example of a different acquisition mode.

Spatial Scan measures points spaced by a specified distance. Each time the reflector moves the prescribed distance from the previous measurement, another measurement is triggered. Be aware that this distance will not be perfect, as hardware sampling rate, reflector speed, computer clock speed, network latency, and other factors introduce lag between when the prescribed increment is detected by the instrument interface and when a measurement is taken.

In the above example a button press will start a "stable" measurement profile that will monitor the reflector until it becomes stable and then start measuring. It will then measure at 100Hz (typically modern trackers measure at maximum speed) checking to see if the reflector has moved 0.25" and when it has, it will record a point. This will continue until the beam break.

 

Measurement Profile Customization

The Save and Save As buttons provide the ability to edit the existing measurement profile and save it with new name as needed.

The Iterate this Profile [ ] times option offers the ability to include an automatic repeat. The measurement would then only need to be triggered once and could be executed multiple times one ofter another. This can be quite helpful in repeated part inspections such as inspecting a series of bolt hole patterns for an example.

Additionally, the Acquisition and Operations are selections within a drop-down lists. A new Acquisition or Operation can be selected to modify either the measurement or data recording aspects of the profile.

 

Current list of Measurement Profiles

SA provides a default list of measurement profiles. Measurement profiles can be added and edited and are saved in the persistence file for the particular instrument model. This is typically found in the C:\Analyzer Data\Persistence directory and can be copied between computers as needed. To access the measurement profiles press the folder icon:

These measurement profiles can be sorted by clicking on the column header by name, Acquisition, and Operation used. The Quick Select column shows the 4 designated profiles displayed on the interface for quick access, and the Show column offers the ability to reduce the number of profiles displayed in the measurement profile drop-down list.
