Which color indicates caution range on the data display label?

• A. Yellow
• B. Red
• C. Green
• D. Blue

Answer: (A)

Yellow indicates caution. It signals that a parameter is approaching its limits and deserves attention, but it isn’t an immediate emergency. The display uses color to convey status at a glance: green means normal, yellow means caution, red means a fault or hazardous condition, and blue often denotes informational or standby status. So when you see yellow on the data display label, you should monitor the parameter closely and be prepared to adjust or verify as needed before it worsens.
