What are the AIP's two modes of operation?

• A. Normal Display Mode, User Data Entry Mode
• B. Display Only Mode, Config Mode
• C. Measurement Mode, Diagnostic Mode
• D. Automatic Mode, Manual Mode

Answer: (A)

The device operates in two modes: Normal Display Mode and User Data Entry Mode. Normal Display Mode is where you monitor live readings, system status, alarms, and trends—it's focused on viewing information quickly and clearly. User Data Entry Mode is where you input or adjust information—calibrations, parameters, or logged data—so you can configure how the system behaves or records information.

This separation is helpful because it makes watching and configuring distinct tasks, reducing the chance of accidental changes during normal monitoring. When you just need to observe, you stay in Normal Display Mode; when you need to set values or log data, you switch to User Data Entry Mode. The other pairings describe modes that don’t capture this clear division between displaying information and entering data, or they describe different concepts like diagnostic, measurement, or automatic/manual control, which aren’t the same two-mode pairing described here.
