Status.node_Enable - Keithley 2651A Reference Manual

Section 7: Command reference
Details
These attributes are used to read or write to the measurement event voltage limit summary registers. 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 B0, and the most significant bit is Bit B15.
For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to

Bit Value
B0 Not used
B1
status.measurement.voltage_limit.SMUA
B2-B15 Not used
As an example, to set bit B1 of the measurement event voltage limit summary enable register, set
status.measurement.voltage_limit.enable = status.measurement.voltage_limit.SMUA.
In addition to the above constant, measurementRegister can be set to the numeric equivalent of the bit to set.
Example
status.measurement.voltage_limit.enable =
status.measurement.voltage_limit.SMUA
