CWT Data Recording & Reporting 5

Question 1

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?

Accepted Answer

The MPE is determined by scale division value and number of scale divisions at the applied load

Answer

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.

Question 2

When preparing a shift-end weighing report, the operator discovers two transaction numbers are missing from the sequential log. The correct action is to:

Accepted Answer

Document the missing numbers in the report and initiate an investigation

Answer

Missing transaction numbers must be documented and investigated to determine whether records were lost, suppressed, or indicate equipment malfunction.

Question 3

In electronic weight recording systems, what is the function of a 'data audit trail'?

Accepted Answer

It creates an immutable log of all recorded transactions, edits, and operator actions with timestamps

Answer

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.

Question 4

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?

Accepted Answer

2,000 bushels

Answer

112,000 lb ÷ 56 lb/bushel = 2,000 bushels; the standard bushel weight for corn is 56 pounds.

Question 5

Which practice best protects the integrity of electronic weight records against unauthorized alteration?

Accepted Answer

Using password-protected access controls and cryptographic checksums on stored records

Answer

Password-protected access combined with cryptographic checksums prevents unauthorized edits and detects any tampering with stored electronic records.
