The status parameter provides additional information about the reading. The options are shown in
the following table.
Parameter Description
buffer.STAT_LIMIT1_HIGH
Reading is above high limit 1
buffer.STAT_LIMIT1_LOW
Reading is below low limit 1
buffer.STAT_LIMIT2_HIGH
Reading is above high limit 2
buffer.STAT_LIMIT2_LOW
Reading is below high limit 2
buffer.STAT_ORIGIN
A/D converter from which reading
originated; for the 2470, this will always be 0
(main)
buffer.STAT_QUESTIONABLE
Measure status questionable
buffer.STAT_REL
Relative offset
buffer.STAT_SCAN
Scan
buffer.STAT_START_GROUP
First reading in a group
buffer.STAT_TERMINAL
Measure terminal, front is 1, rear is 0
Example 1
extBuffer = buffer.make(100, buffer.STYLE_WRITABLE)
buffer.write.format(extBuffer, buffer.UNIT_WATT, buffer.DIGITS_3_5)
buffer.write.reading(extBuffer, 1)
buffer.write.reading(extBuffer, 2)
buffer.write.reading(extBuffer, 3)
buffer.write.reading(extBuffer, 4)
buffer.write.reading(extBuffer, 5)
buffer.write.reading(extBuffer, 6)
printbuffer(1, 6, extBuffer.readings, extBuffer.units)
Creates a 100-point reading buffer named extBuffer. Style is writable.
Set the data format to show units of watts with 3½ digit resolution.
Write 6 pieces of data into the buffer.
Print the buffer, including the readings and units.
Read the buffer.
Output:
1, Watt DC, 2, Watt DC, 3, Watt DC, 4, Watt DC, 5, Watt DC, 6, Watt DC
Example 2
extBuffer = buffer.make(100, buffer.STYLE_WRITABLE_FULL)
buffer.write.format(extBuffer, buffer.UNIT_WATT, buffer.DIGITS_3_5,
buffer.UNIT_WATT, buffer.DIGITS_3_5)
buffer.write.reading(extBuffer, 1, 7)
buffer.write.reading(extBuffer, 2, 8)
buffer.write.reading(extBuffer, 3, 9)
buffer.write.reading(extBuffer, 4, 10)
buffer.write.reading(extBuffer, 5, 11)
buffer.write.reading(extBuffer, 6, 12)
printbuffer(1, 6, extBuffer.readings, extBuffer.units, extBuffer.extravalues,
extBuffer.units)
Creates a 100-point reading buffer named
extBuffer
. Style is full writable.
Set the data format to show units of watts with 3½ digit resolution for the first value and for the second value in
the buffer index.
Write 12 pieces of data into the buffer.
Print the buffer, including the readings and units.
Read the buffer.
