What information is typically required on a printed weight ticket from a legal-for-trade scale system?
Answer: Date, time, gross weight, tare weight, net weight, and transaction identifier
A standard legal-for-trade weight ticket includes date, time, gross weight, tare weight, net weight, and often operator or transaction identifiers to serve as a verifiable legal record.
What is 'alibi memory' in a certified scale indicator?
Answer: A secure internal log that records every weighing transaction for audit purposes
Alibi memory is a secure, tamper-evident internal record of all weighing transactions stored in the indicator, used to verify or dispute weight readings after the fact.
What is the primary purpose of a remote display in a retail scale installation?
Answer: To show the weight reading to a customer or operator at a location separate from the main indicator
A remote display repeats the weight reading from the main indicator so it can be seen by a customer at a checkout counter or an operator positioned away from the scale.
What does a 'checkweigher' automatically do in a production line scale system?
Answer: Weighs products on a conveyor and accepts or rejects them based on weight tolerance limits
A checkweigher automatically weighs products moving on a conveyor and activates accept or reject mechanisms based on whether each item falls within pre-set weight tolerance limits.
What does 'weigh-in-motion' (WIM) mean in a truck scale installation?
Answer: A vehicle is weighed while traveling across the scale platform without coming to a complete stop
Weigh-in-motion technology captures the weight of a vehicle as it drives across the scale at reduced speed, eliminating the need for the truck to stop completely.
What scale indicator feature records and retains calibration parameters so they can be restored after a power failure?
Answer: Non-volatile memory (EEPROM or flash) that retains calibration data without power
Scale indicators use non-volatile memory such as EEPROM or flash storage to retain calibration parameters, so the scale does not need to be recalibrated every time power is cycled.
