Usage
statusInformation = bufferVar .sourcestatuses[ N ]
statusInformation The status value when reading
N
of the specified buffer was acquired;
Source status values are:

Overvoltage protection was active:
buffer.STAT_PROTECTION

Measured source value was read:
buffer.STAT_READBACK

Overtemperature condition was active:
buffer.STAT_OVER_TEMP

Source function level was limited:
buffer.STAT_LIMIT

Four-wire sense was used:
buffer.STAT_SENSE

Output was on:
buffer.STAT_OUTPUT
bufferVar The name of the reading buffer, which may be a default buffer (
defbuffer1
or
defbuffer2
) or a user-defined buffer
N
The reading number
N
; can be any value from 1 to the number of readings in the
buffer; use the
bufferVar. n
command to determine the number of readings in
the buffer
Details
This buffer recall attribute holds 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 for each
measurement made. See the following table for values.
Buffer status bits for source function when reading was acquired
Bit Name Decimal value Description
2 STAT_PROTECTION 4 Overvoltage protection was active
3 STAT_READBACK 8 Measured source value was read
4 STAT_OVER_TEMP 16 Overtemperature condition was active
5 STAT_LIMIT 32 Source function level was limited
6 STAT_SENSE 64 Four-wire sense was used
7 STAT_OUTPUT 128 Output was on
