Important:  When selecting a scale for Package Checking, make sure that it meets Handbook 133 Scale Requirements (2.2.1.).  The fact that the scale listed above may be compatible with WinWam, it does not  mean that the particular model meets Handbook 133 requirements.

NIST Handbook 133    2.2.1    Scale Requirements:

Use a scale (for this handbook the term “scale” includes balances) that has at least 100 scale divisions.  It must have a load-receiving element of sufficient size and capacity to hold the packages during weighing.  It also requires a scale division no larger than 1/6 of the Maximum Allowable Variation (MAV See MAXIMUM ALLOWABLE VARIATION) for the package size being weighed.  The MAV See MAXIMUM ALLOWABLE VARIATION/6 requirement ensures that the scale has adequate resolution to determine the net contents of the packages.  Subsequent references to product test results requiring the agreement to within one scale division are based on scale divisions that are equal to or only slightly smaller than the MAV See MAXIMUM ALLOWABLE VARIATION/6.  (See Appendix A, Table 2‑5. “Maximum Allowable Variations (MAVs) for Packages Labeled by Weight.”)
