The options for
<bufferElements>
are described in the following table.
Option Description
DATE The date when the data point was measured
FORMatted The measured value as it appears on the front panel
FRACtional The fractional seconds for the data point when the data point was measured
READing
The measurement reading based on the
[:SENSe[1]]:FUNCtion[:ON]
setting; if
no buffer elements are defined, this option is used
RELative The relative time when the data point was measured
SEConds
The seconds in UTC (Coordinated Universal Time) format when the data point was
measured
SOURce The source value; if readback is ON, then it is the readback value, otherwise it is the
programmed source value (see
:SOURce[1]:<function>:READ:BACK (on page
12-84))
SOURFORMatted
The source value as it appears on the display
SOURSTATus The status information associated with sourcing. The values returned indicate the
status of the following conditions:

Overvoltage protection was active

Measured source value was read

Overtemperature condition existed

Source function level was limited

Four-wire sense was used

Output was on
SOURUNIT
The unit of value associated with the source value
STATus The status information associated with the measurement; see the "Buffer status bits
for sense measurements" table below
TIME The time for the data point
TSTamp The timestamp for the data point
UNIT
The unit of measure associated with the measurement
The
STATus
buffer element returns status values for the readings in the buffer. The status values are
integers that encode the status value. Refer to the following table for values.
Buffer status bits for sense measurements
Bit (hex) Name Decimal Description
0x0001 STAT_QUESTIONABLE
1 Measure status questionable
0x0006 STAT_ORIGIN 6 A/D converter from which reading originated; for the
2470, this will always be 0 (main)
0x0008 STAT_TERMINAL
8 Measure terminal, front is 1, rear is 0
0x0010 STAT_LIMIT2_LOW 16 Measure status limit 2 low
0x0020 STAT_LIMIT2_HIGH 32 Measure status limit 2 high
0x0040 STAT_LIMIT1_LOW
64 Measure status limit 1 low
0x0080 STAT_LIMIT1_HIGH 128 Measure status limit 1 high
0x0100 STAT_START_GROUP 256 First reading in a group
