Effects of positive transitions on the Measurement Event Register:
Positive transition effect on
Measurement event Measurement Event Register
Reading overflow Sets B0 when reading exceeds range limits.
Low limit 1 Sets B1 when reading is less than the low limit 1 setting.
High limit 1 Sets B2 when reading is greater than the low limit 1 setting.
Low limit 2 Sets B3 when reading is less than the low limit 2 setting.
High limit 2 Sets B4 when reading is greater than the high limit 2 setting.
Reading available Sets B5 after a reading is taken and processed.
Reading underflow Sets B6 when an ohms reading is below the lower range limit.
Buffer available Sets B7 when the trace buffer has at least two readings.
Buffer half full Sets B8 when the trace buffer becomes half full.
Buffer full Sets B9 when the trace buffer becomes full.
Sequence reading available Sets B10 when an Alternating Polarity test sequence reading
becomes available.
Buffer pretriggered Sets B11 when the trace buffer pretrigger event occurs.
Out of Limits Sets B12 when a noise spike occurs.
Fixture lid closed Sets B13 when fixture lid is closed.
V-source compliance Sets B14 when V-source goes in compliance.
