This command initiates a Drift Check operation. It allows a reference group to be measured for comparison and drift analysis through the use of the Drift Check dialog.
0 |
Collection Instrument ID |
Instrument ID |
The instrument ID of the instrument to perform the drift check. |
1 |
Collection Object Name |
Reference Group Name |
The name of the reference point group. |
2 |
Collection Object Name |
Actuals Group (to be measured) |
The group into which measurements should be placed. |
3 |
Double |
Tolerance |
An allowable tolerance for each individual point being checked. |
4 |
Integer |
Minimum Point Count |
Required number of measurements - enter 0 to disable this requirement. |
5 |
Boolean |
Use Closest Reference Point |
True will enable this option. |
6 |
Double |
Max Error |
The Max error in the drift check |
3 |
Double |
RMS Error |
The RMS error for the drift check |
4 |
Boolean |
Instrument Added? |
True indicates a new instrument was added. |
5 |
Collection Instrument ID |
New Instrument |
Name of the newly added instrument. |
SUCCESS |
The measurements were completed successfully and tolerances were not exceeded. |
PARTIAL SUCCESS |
Some or all points out of tolerance, or new station added. |
FAILURE |
The instrument or reference group was not found, minimum point count was not met, or the operation was manually cancelled. |
The instrument must be in the active collection, and its interface must be running. Also, silent mode will not block the dialog display but will cause the multipoint measurement sequence to start when the dialog opens.
Additional notes:
The “Tolerance” value effects the colorization of the “dMag” column in the dialog as well as the Step Status Result. The return status will be Partial Success if any points are over tolerance, even if the operator chooses “Finished--Drift Acceptable”.
The “Finished – Drift Acceptable” button will be unavailable until minimum point count is met. Counts less than three are allowed for interim Drift Checks, but transform options are displayed only after the minimum point count and at least three points are measured.
If “Use Closest Reference Point” is TRUE, the operator can measure the points in any order and the incoming measurement will be associated with the closest nominal point.
