USS Merlin :: Wiki - Diagnostics Levels

Diagnostics are Engineering and Operations analysis programs used on Starfleet vessels and facilities that are intended to permit an automated analysis of any malfunctions in ship systems. Most key systems have 5 diagnostic levels, where 5 is the quickest and most simplistic and 1 is the longest and most thorough.

Level	Diagnostic Information


LEVEL 5	Extremely quick superficial general maintenance scan. Time: 5 -10 Seconds Note: The system in question is to remain on-line during this test.


LEVEL 4	A little slower, more of a complete scan. Normally used during a shift change in order to generate an accurate report for the duty officer. Time: 30 Seconds to 1 Minute Note: The system in question is to remain on-line during this test.


LEVEL 3	Very complete scan. This scan is used on computer systems only. Time: 2 - 10 minutes Note: The system in question can remain on-line during this test.


LEVEL 2	This is a combination of a computer scans which must then be verified by an engineer. Not an exhaustive scan and it is subject to errors. Time: 1.5 - 2 hours Note: The system in question should be shut down before this test can be performed.


LEVEL 1	The most comprehensive diagnostic. Extremely through computer diagnostic all followed up by an engineering team's visual diagnosis. Exhaustive testing. Time: 2 - 3 hours Note: The system in question must be offline during this test.
