External voltage supply name (VADP, VBT, VSBT)
External load name (LOADR, LOADI)
Voltage at internal test point TPyyy. For example, V(TP12) means the voltage at
TP12.
Voltage at jack terminal Jxx
Voltage at test point "XXX". For example, V(ACDET) means the voltage at the test
point which is marked as "ACDET".
Voltage across point XXX and YYY.
Current going out from the YYY terminal of jack XX.
Terminal or pin BBB of jack xx
Internal jumper Jxx terminals are shorted
Internal jumper Jxx terminals are open
ON: Internal jumper Jxx adjacent terminals marked as "YY" are shorted
Check specified parameters A, B. If measured values are not within specified limits
the unit under test has failed.
Observe if A, B occur. If they do not occur, the unit under test has failed.
