Number of Elements - This field specifies the number of elements to check. Gaps in element types and
addresses are automatically handled until a quantity of physical elements equal to this number has been
checked. If this field is 0, the range checked will start with the Starting Element Address and continue
through all remaining elements. This field is ignored if the Range field is 0.
No Barcode Labels (NBL) – A value of 0 indicates that the specified elements will be checked for all
relevant status, including bar code labels. A value of 1 indicates that elements will be checked for media
presence only (no bar code labels).
