What percentage threshold triggers the RSVR LOW caution?

• A. 60%
• B. 40%
• C. 80%
• D. 20%

Answer: (A)

This question tests how threshold levels are used to flag abnormal readings. RSVR LOW appears when the RSVR value drops to a defined fraction of its normal/reference level. The chosen threshold is 60%, so when the RSVR reading falls to 60% of its nominal value, the system triggers the caution to alert you that the subsystem is operating well below its expected performance.

Why 60% works as the trigger: it gives a timely warning of a meaningful degradation without sounding alarms for minor variations. If the value stays above 60%, you’re generally within acceptable limits and no action is required. If it drops much further (say to 40% or 20%), that would typically correspond to a more serious condition or a different caution level, which is not what this particular warning is designed to signal.

In short, 60% is the designed point at which a drop becomes significant enough to alert you to inspect the RSVR system, while higher values stay in the normal range and lower values would trigger other, more severe indications.
