Measurement Event Register:
Bit B0, Reading Overflow (ROF) – Set bit indicates that the reading exceeds the measure-
ment range of the instrument.
Bit B1, Low Limit1 (LL1) – Set bit indicates that the reading is less than the Low Limit 1
setting.
Bit B2, High Limit1 (HL1) – Set bit indicates that the reading is greater than the High Limit
1 setting.
Bit B3, Low Limit 2 (LL2) – Set bit indicates that the reading is less than the Low Limit 2
setting.
Bit B4, High Limit 2 (HL2) – Set bit indicates that the reading is greater than the High Limit
2 setting.
Bit B5, Reading Available (RAV) – Set bit indicates that a reading was taken and processed.
Bit B6 – Not used.
Bit B7, Buffer Available (BAV) – Set bit indicates that there are at least two readings in the
trace buffer.
Bit B8, Buffer Half Full (BHF) – Set bit indicates that the trace buffer is half full.
Bit B9, Buffer Full (BFL) – Set bit indicates that the trace buffer is full.
