Attribute Measurement voltage limit event register set.
Usage Reads condition, enable, event, NTR and PTR registers:
measreg = status.measurement.voltage_limit.condition
measreg = status.measurement.voltage_limit.enable
measreg = status.measurement.voltage_limit.event
measreg = status.measurement.voltage_limit.ntr
measreg = status.measurement.voltage_limit.ptr
Writes to enable, NTR and PTR registers:
status.measurement.voltage_limit.enable = measreg
status.measurement.voltage_limit.ntr = measreg
status.measurement.voltage_limit.ptr = measreg

• This attribute is used to read or write to the measurement voltage limit registers.
Remarks
• Reading a status register returns a value. The binary equivalent of the returned value
indicates which register bits are set. The least significant bit of the binary number is
bit 0, and the most significant bit is bit 15.
For example, assume value 6 is returned for the enable register. The binary
equivalent is 0000000000000110. This value indicates that bit B1(SMUA) and bit B2
(SMUB) are set.
• The used bits of the measurement voltage limit registers are described as follows:
• Bit B1, SMUA – Set bit indicates the enabled VLMT bit for the SMU A
measurement register is set.
• Bit B2, SMUB – Set bit indicates the enabled VLMT bit for the SMU B
measurement register is set.
Details See "Measurement Event
Example Sets the SMUA bit of the measurement voltage limit enable register:
