Not applicable Not applicable
Usage
reading = bufferVar.readings[N]
reading
The value of the reading in the specified reading buffer
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
Example
reset()
testData = buffer.make(50)
trigger.model.load("SimpleLoop", 3, 0, testData)
trigger.model.initiate()
waitcomplete()
for x = 1, 3 do printbuffer(x, x, testData.readings, testData.sourcevalues,
testData.relativetimestamps) end
Create a reading buffer named testData, configure the instrument to make three measurements, and store
the readings in the buffer.
Print the three readings in testData, including the measurement, source value, and relative timestamp.
Output:
-9.6420389034124e-12, 2, 0
