When measuring with the LR in different orientations, such that it is not oriented vertically with respect to gravity, additional compensations should be considered for optimal accuracy. Monument Compensation Model (MCM) calibrations can be used for this purpose. Settings>MCM Database opens a dialog which provides both a list of existing calibrations and offers the ability to record an additional one.
MP/SDK script control is also essential for the MCM process. The following commands are available:
LR APDIS Perform MCM Calibration. Allows a point group to be selected and measured to build a new calibration
LR APDIS Activate MCM Calibration. Provides the ability to set the active calibration when desired.
LR APDIS Get Active MCM Calibration. Provides the ability to check the current MCM calibration in use.
Different LR models come with both different capabilities and licensing restrictions. The current capability of your model can be checked under Instrument>Hardware Capabilities.
There are several automatic measure functions that can be triggered from the Instrument menu within SA. Auto Measure opens a dialog that allows selection, drive and automatic measurement options. Batch commands are much simpler and run through a list of targets in one pass only. These commands exist for both points and vectors. Vectors offer the added benefit of allowing the LR to search the nominal vector for the actual surface intersection point. For more information take a look at the instruments section HERE.
Starting with SA version 2022.2 there is now an Auto-Measure option to process a list of GR-Features. This is currently supported through the MV430/MV450 Gauging Engine (GE). Currently supported geometry types include:
circles
rounded slots
rectangular slots
If the user’s job has a list of GR-Features with predefined nominals, SA can measure this list using the LR’s Gauging Engine capability. See Measure Batch of Features
Nikon Interface Controls
There are GE specific target profiles that can be linked to individual Features in the tree. These profiles can be edited and saved for specific features:
To configure GE target profile / measurement settings on Nikon AP- DIS LR application, use the Gauging Engine section in the Target Manager dialog:
The selected GE Target definition setting show a short description on the bottom from the Nikon GE specifications.
Users can define whether to send to SA a measured geometry and/or scan data in form of a cloud. By default, a measured geometry will be sent automatically to SA.
SA Feature Configuration
You can optionally assign a predefined measurement profile to a feature. If this step is skipped, measurement defaults will be used.
To assign a specific measurement profile to a feature, R-click in SA tree on geometry relationship and select the Trapping Controls >>Configure Instrument
You can select a measurement profile for a feature from a list of available GE settings received from LR interface Target Manager:
The same dialog allows you to apply the same settings to selected features or reset to defaults.
Triggering the Measurement Process
To start the measurement process, navigate to the Instrument tab of the SA ribbon and select Auto Measure >> Measure Batch of Features.
SA application prompts you to select a list of GR-Features to measure and then sends this list to the LR for measurement using Gauging Engine.
On completion of each measurement, SA receives a measurement result (geometry and / or scan data) and immediately associates it with the geometry relationship.
Each measured object (geometry and / or cloud) lists the measurement settings details in the job units.
A list of MP command strings can be found in the interface under Help>Help Topics>Measurement Plans (MP). This dialog offers a full list of strings that can be used with the Set Instrument Measurement Mode/ Profile and Instrument Operational Check commands.
