V(XXX, YYY):
Voltage across point XXX and YYY.
I(JXX(YYY)):
Current going out from the YYY terminal of jack XX.
Jxx(BBB):
Terminal or pin BBB of jack xx
Jxx ON :
Internal jumper Jxx terminals are shorted
Jxx OFF:
Internal jumper Jxx terminals are open
Jxx (-YY-) ON:
Internal jumper Jxx adjacent terminals marked as YY are shorted
Measure:
→
A,B Check specified parameters A, B. If measured values are not within specified limits, the
unit under test has failed.
Observe:
→
A,B Observe if A, B occur. If they do not occur, the unit under test has failed.
