Series 2600 System SourceMeters Reference Manual
• This attribute is used to read or write to the measurement 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 257 is returned for the register. The binary equivalent is
0000000100000001. This value indicates that bit B1(VLMT) and bit B8 (BAV) are set.
• The used bits of the measurement registers are described as follows:
• Bit B0, VLMT – Set bit indicates that the voltage limit was exceeded. This bit will
be updated only when a measurement is taken or
invoked.
• Bit B1, ILMT – Set bit indicates that the current limit was exceeded. This bit will be
updated only when a measurement is taken or
invoked.
• Bit B7, ROF – Set bit indicates that an overflow reading has been detected.
• Bit B8, BAV – Set bit indicates that there is at least one reading stored in either or
both of the non-volatile reading buffers.
• Bit B11, OE – Set bit indicates that output enable has been asserted.
• Bit B13, INST – Set bit indicates that a bit in the measurement instrument
summary register is set.
Details See "Measurement Event
Example Sets the BAV bit of the measurement enable register:
status.measurement.enable = status.measurement.BAV
