Under NIST Handbook 44, what is the maximum permissible error (MPE) classification for a Class III scale used in commercial grain weighing at 10,000 lb?
Answer: The MPE is determined by scale division value and number of scale divisions at the applied load
NIST Handbook 44 defines MPE for Class III scales based on scale division (d) value and the number of divisions encompassed by the test load.
When preparing a shift-end weighing report, the operator discovers two transaction numbers are missing from the sequential log. The correct action is to:
Answer: Document the missing numbers in the report and initiate an investigation
Missing transaction numbers must be documented and investigated to determine whether records were lost, suppressed, or indicate equipment malfunction.
In electronic weight recording systems, what is the function of a 'data audit trail'?
Answer: It creates an immutable log of all recorded transactions, edits, and operator actions with timestamps
An electronic data audit trail records every transaction and system event with timestamps and operator IDs, providing an immutable record for compliance and dispute resolution.
A weighing facility reports weights to a grain elevator in bushels, but the scale measures in pounds. For corn at 56 lb/bushel, a net weight of 112,000 lb equals how many bushels?
Answer: 2,000 bushels
112,000 lb ÷ 56 lb/bushel = 2,000 bushels; the standard bushel weight for corn is 56 pounds.
Which practice best protects the integrity of electronic weight records against unauthorized alteration?
Answer: Using password-protected access controls and cryptographic checksums on stored records
Password-protected access combined with cryptographic checksums prevents unauthorized edits and detects any tampering with stored electronic records.
A weighmaster issues a certificate for 45,600 lb net weight. The applicable commodity requires reporting to the nearest 100 lb. How should the net weight be reported?
Answer: 45,600 lb (no rounding needed)
45,600 lb is already an exact multiple of 100 lb, so no rounding is necessary and the value is reported as-is.
What distinguishes a 'weighmaster certificate' from a standard commercial weight ticket in US legal-for-trade weighing?
Answer: A weighmaster certificate is issued by a licensed or bonded individual whose signature carries legal authority for the stated weight
A weighmaster certificate is signed by a licensed or bonded weighmaster whose official signature gives the document legal standing as prima facie evidence of the stated weight.
