Last Performed Check Status
Every time you get a tracker at hand, you need to get to know its performance and usage status, such as which accuracy it can achieve, if it needs to perform checks before measuring, or it is ready for use because all checks are good.
To give you a quick overview of the status of a tracker, SFx Asset Management introduces the last performed check status for laser trackers. You can get a glimpse of the tracker status by the indicator of the last performed check status in the Asset Dashboard.
Left: Card View / Right: Table View
Note
Currently, the last performed check only refers to the Field Checks, including two types of checks: Two Face Check and Scale Bar Check. See Field Checks for details.
This status has nothing to do with the operational status or overall status of a tracker. This is an independent status to help you get to know if a tracker is ready for the next use even if it's offline and not connected to SFx Asset Management.
Worst Check
To comprehend the last performed check status, you need to know what the worst check is.
The worst check depends on the latest performed check of the two types of field checks: Two Face Check and Scale Bar Check based on the availability of each check type.
If both of the latest performed checks are OK, the worst check is OK.
For example, when only the Two Face Check is available, and the latest performed check of this check type is OK, then the worst check is OK.
If one of the latest performed checks is Not OK, then the worst check is Not OK.
For example, when the latest performed check of the Two Face Check is OK, but the latest performed check of the Scale Bar Check is Not OK, then the worst check of this tracker is Not OK.
How to determine if a performed check is OK or not?
When the Tolerance Used <= Acceptance Level, then the performed check is OK.
When the Tolerance Used > Acceptance Level, then the performed check is Not OK.
Last Performed Check
The last performed check status combines the worst check result with the period of validity of the last performed check.
Note
If the period of validity is not set, then the last performed check equals the worst check.
The table below describes the icons of different last performed check statuses.
Icon | Description |
|---|---|
| The green shield indicates the worst check is OK, and the last performed check is OK either because the period of validity is not set or within the preset time period. In this case, at least one check is available for the tracker. |
| The yellow shield indicates the worst check is OK, but the last performed check is Not OK because the period of validity of the last performed check exceeds the preset time period. In this case, at least one check is available for the tracker but the time when the check was performed last time passed too long, and a new check is needed. TipTo set up a period of validity for the last performed check, see Tracker Settings for details. |
| The red shield indicates the worst check is Not OK, and the last performed check is Not OK. In this case, no matter whether the period of validity is set or not, the last performed check keeps in the Not OK state. That is, the tracker can't be used directly. |
| The grey shield indicates no check is available. This status usually happens to new trackers because no check is performed yet since a tracker has been onboarded to SFx Asset Management. |
Tracker Settings
When you consider a new check for the tracker is necessary after a period of time, you can set up a period of validity for the last performed check. When the time approaches, the status icon of the last performed check becomes yellow to remind you that a new check is needed.
Follow these steps to set up a period of validity for the last performed check.

On the Edit this Asset screen, scroll down to Tracker Settings, and select a time period from the drop-down list.
