Continuous ATG tests gather data during which times?

Continuous ATG tests gather data during which times?

• A. Automatically during the dispensing events
• B. Manually by the operator
• C. Randomly at irregular intervals
• D. Automatically during the quiet intervals between dispensing/delivery events

Answer: (D)

Continuous ATG tests are meant to monitor inventory without interrupting operations, so measurements should be taken when the tank is not actively dispensing or receiving fuel. During the quiet intervals between dispensing and delivery events, the fuel is more stable, with less movement, temperature shifts, or pressure changes that could skew readings. Automatic data collection ensures consistent, unbiased data without relying on an operator to initiate measurements, and avoids gaps that would come from random or manual timing. Choosing this timing keeps the data reliable and representative of the tank’s true level.
