Details
This read-only buffer recall attribute is like an array (a Lua table) of the status values for all the readings in the
buffer. The status values are floating-point numbers that encode the status value; see the following table for
values.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the reading buffer
is saved to nonvolatile memory.
Buffer status bits
Bit Name Hex value Description
B1
Overtemp
0x02
Over temperature condition
B2
AutoRangeMeas
0x04
Measure range was autoranged
B3
AutoRangeSrc
0x08
Source range was autoranged
B4
4Wire
0x10
4-wire (remote) sense mode enabled
B5
Rel
0x20
Relative offset applied to reading
B6
Compliance
0x40
Source function was limited because
the complementary function would be
over the compliance limit
B7
Filtered
0x80
Reading was filtered
