CWT Data Recording & Reporting 4 — Questions and Answers
Question 1: An automated truck scale system prints a ticket with a weight of 0 lbs due to a sensor fault. The operator should:
- File the ticket as-is and note 'sensor issue' in the margin
- Void the ticket, remove the vehicle, resolve the fault, and reweigh (Correct answer)
- Manually write in the expected weight based on prior deliveries
- Average the last three weights and use that value
Correct answer: Void the ticket, remove the vehicle, resolve the fault, and reweigh
A zero-weight reading due to a sensor fault indicates an equipment failure that must be corrected before any valid record can be produced.
Question 2: In a chain-of-custody weighing scenario, why is an unbroken sequence of transaction numbers important?
- It helps the printer conserve ink
- It detects missing, inserted, or altered records in the transaction log (Correct answer)
- It allows customers to predict future ticket numbers
- It reduces the time needed to close out daily reports
Correct answer: It detects missing, inserted, or altered records in the transaction log
Sequential transaction numbers create an auditable trail; gaps or duplicates indicate potential tampering, lost records, or system errors.
Question 3: Which of the following data elements is NOT typically required on a standard commercial weight ticket?
- Date and time of weighing
- Net weight
- Driver's personal home address (Correct answer)
- Scale identification number
Correct answer: Driver's personal home address
A driver's personal home address is not a required element on commercial weight tickets; date/time, net weight, and scale ID are standard required fields.
Question 4: A facility uses both US customary (lb) and metric (kg) scales. When generating a summary report combining data from both, the operator must:
- List all weights as recorded without conversion and note the mixed units
- Convert all weights to a single consistent unit before totaling (Correct answer)
- Report lb weights and kg weights in separate columns with no combined total
- Use whichever unit appears most frequently in the dataset
Correct answer: Convert all weights to a single consistent unit before totaling
Combining weights from different unit systems without conversion produces arithmetically invalid totals; all values must first be converted to a common unit.
Question 5: When a digital indicator displays a weight with the letter 'E' preceding the value, this typically indicates:
- The weight has been electronically certified
- An error condition exists and the weight should not be recorded (Correct answer)
- The reading is in metric units
- The scale has entered energy-saving mode
Correct answer: An error condition exists and the weight should not be recorded
An 'E' prefix on a digital indicator display signifies an error condition, meaning the displayed value is unreliable and must not be used for recording.
Question 6: What is the purpose of the 'tare memory' function on a weighing terminal in data recording?
- To store customer billing information
- To recall a previously stored container weight, eliminating the need to reweigh the empty container each time (Correct answer)
- To back up weight data to an external server
- To lock the scale from unauthorized use
Correct answer: To recall a previously stored container weight, eliminating the need to reweigh the empty container each time
Tare memory stores known container or vehicle weights so operators can instantly subtract them without requiring a physical empty weigh-in each transaction.
Question 7: A daily scale report shows total gross weight of 850,000 lb, total tare weight of 320,000 lb, and total net weight of 532,000 lb. This data contains:
- No errors; the figures are internally consistent
- An arithmetic error; net should be 530,000 lb (Correct answer)
- An arithmetic error; net should be 1,170,000 lb
- A tare error; tare exceeds allowable limits
Correct answer: An arithmetic error; net should be 530,000 lb
850,000 − 320,000 = 530,000 lb, not 532,000 lb; the reported net weight contains a 2,000 lb arithmetic discrepancy that must be investigated.
