Is there a way to group multiple assets that need to be calibrated?
Yes. You can use the "Loop Calibration" feature in the Locations (Cal) application to achieve this. To start, go to the Locations (Cal) application and bring up the location that you want to associate your assets to.
Once the location is displayed, check the box labeled "Loop Calibration". This designates the location as part of a loop calibration.
After updating the location, you can then associate assets with this location via the Assets (Cal) application.
