Which of the following is NOT a requirement for a retail motor fuel dispenser?

A retail motor fuel dispenser commonly must meet specific requirements to ensure accurate and transparent service to consumers. Among these, the expectation of displaying totalizer readings is crucial, as it allows customers to see the cumulative volume of fuel dispensed, maintaining clarity about what they are purchasing.

Another requirement is that dispensers are equipped with a functional test measure, often referred to as a calibration check. This ensures that the device is measuring fuel accurately, which is essential for compliance with regulatory standards and consumer trust.

The option referencing non-resettable dispensers highlights the necessity for consumers to see a continuous count of the total amount dispensed without the ability to alter or reset it. This characteristic helps discourage tampering and enhances transparency in transactions.

Conversely, the requirement to show min and max capacities on the badge is less common in practice. While having this information might be helpful for consumers, it is not a standard requirement. Thus, this distinguishes it from the other three elements, which are fundamental and necessary for the operation of the retail fuel dispensers.
