Measurement Event Reading Overflow Summary
This summary register set feeds to ROF bit B7 of the Measurement Event Register. Used
summary bits for this register include B1 (SMUA) and B2 (SMUB). A set bit indicates that a reading
overflow has occurred for a SMU (A or B).
Measurement Event Buffer Available Summary
This summary register set feeds to BAV bit B8 of the Measurement Event Register. Used summary
bits for this register include B1 (SMUA) and B2 (SMUB). A set bit indicates that a buffer is available
for a SMU (A or B).
Measurement Event SMU A Summary Register
This SMU summary register set feeds to bit B1 (SMUA) of the Measurement Status Instrument
Summary Register. Used summary bits for this register include B0 (VLMT), B1 (ILMT), B7 (ROF)
and B8 (BAV). A set bit indicates that the corresponding measurement event for SMU A has
occurred.
Measurement Event SMU B Summary Register
This SMU summary register set feeds to bit B2 (SMUB) of the Measurement Status Instrument
Summary Register. Used summary bits for this register include B0 (VLMT), B1 (ILMT), B7 (ROF)
and B8 (BAV). A set bit indicates that the corresponding measurement event for SMU B has
occurred.
Measurement Event Instrument Summary Register
This summary register is fed from the SMU summary registers and then feeds to bit B13 (INST) of
the Measurement Event Summary Register. Used summary bits for this register include B1
(SMUA) and B2 (SMUB). A set bit indicates that an measurement event has occurred for SMU A
and/or SMU B.

Command
To set register bits:
status.measurement.* = status.measurement.VOLTAGE_LIMIT
status.measurement.* = status.measurement.VLMT
status.measurement.* = status.measurement.CURRENT_LIMIT
status.measurement.* = status.measurement.ILMT
status.measurement.* = status.measurement.READING_OVERFLOW
status.measurement.* = status.measurement.ROF
status.measurement.* = status.measurement.BUFFER_AVAILABLE
status.measurement.* = status.measurement.BAV
status.measurement.* = status.measurement.OUTPUT_ENABLE
status.measurement.* = status.measurement.OE
status.measurement.* = status.measurement.INSTRUMENT_SUMMARY
status.measurement.* = status.measurement.INST
To read registers:
print(status.measurement.*)
print(status.measurement.condition)
print(status.measurement.event)
