Wrap the strap snugly around the forearm near the elbow and fasten with the Velcro tabs. This can be worn over clothing or lab coats. While holding the instrument, place the cable under the small tubular tab on the arm strap and fasten the tab down. Adjust it so that the length of cable between the strap and your hand is sufficient to allow for comfortable use. Significantly reduce the effort required to manage the instrument with this simple device.
