In some cases, you might delete gauges to make the gauge dropdown list smaller, without worrying about losing the specific information related to that gauge. You can easily restore that gauge.
1. Select Administration from the navigation menu, and then select Gauges.
2. On the Manage Tester's Gauges page, click Reactivate Gauge next to the gauge you want to restore.
3. When the popup message appears, click OK.
The deleted gauge is moved back to the active Gauge List.
