To optimize your dimensioning performance, follow these recommended tips.
Minimum Range
It is recommended that the distance to a parcel be at least 40 cm (16 in.).
This is important when dimensioning small boxes. If aiming top-down at close range there may be too much IR glare directed at the dimensioning device. It is visible on the display as a light colored area.
When this happens, tilt the dimensioning device slightly to move the glare off of the parcel's top surface.
The glare spot is easily visible in the first image below. The second image shows the result of tilting the dimensioning device leading to a successful dimension in the third image.
Adjust for Glare
Tall Parcels and Countertop Dimensioning
To successfully dimension a parcel, point the on-screen aimer at the top of the parcel. Aim directly above the parcel as much as possible (within 50° of vertical).
If the parcel is very tall or the counter height makes it difficult for the user to fit the entire parcel within the viewfinder, rotate the parcel so that the smallest dimension is the height.
The following figure illustrates turning a box onto its side, allowing the user a better view of the parcel. The user is able to fit the entire parcel on the screen and point the on-screen aimer at the top of the parcel.

Alignment of Parcels within the Viewfinder
The optimal results are obtained when the largest horizontal edge of the parcel is aligned with the largest dimension of the display. This is achieved by using the portrait device orientation when standing next to the smaller side of the parcel and using the landscape device orientation when standing next to the longer side of the parcel.
Parcel Alignment
Dimensioning with Multiple Devices
When using multiple devices to perform dimensioning in close proximity, make sure not to overlap the field-of-views.
As part of the dimensioning process, the ToF camera uses illumination that is not visible to the naked eye. No dimensions are captured when the illumination coming from two or more nearby devices overlaps.

Separated field-of-views
Multiple Parcels in the Field-of-View
When more than one parcel is in the field-of-view, fill the screen as much as possible with the intended target. Ensure that the aimer is centered on top of the intended target during the dimensioning process.
Bounding Lines
Bounding lines that match the edges of the parcel indicate a good result. If bounding lines do not match the edges of the parcel, the user should retry.

Operation in Sunlight
Avoid dimensioning a parcel where the sun is directly in front of you. Dimension with the sun at your back, place the parcel in the shade, or use a top-down view.
Distance to Other Objects
Make sure there is a minimum of 20 cm (7.9 in.) between the target parcel and walls or objects the same height or taller. For large parcels that require an angled view, the time-of-flight signal may be impacted by an adjacent wall or object that is too close to the target parcel.
